1. Introduction

1.1. Background

Athletic performance is closely connected to a variety of factors, with nutrition being a crucial driver [1]. The importance of food choices in optimizing training regimens and improving recovery has become a prominent focus in sports science [2]. From infancy through adolescence to adulthood, lifestyle factors such as nutrition, exercise, and other habits play a pivotal role in shaping athletic abilities and overall health. Vandoni et al. suggested that optimal nutrition and lifestyle habits during early developmental stages can have long-lasting effects on sports performance and health outcomes later in life [3]. Factors such as breastfeeding duration, introduction to solid foods, and physical activity levels during childhood can influence growth, development, and athletic potential. During adolescence, a critical period marked by rapid growth and development, nutritional intake becomes even more crucial for supporting physical activity and optimizing performance. Adolescents engaging in sports activities may have increased energy and nutrient requirements, necessitating a balanced diet rich in essential nutrients to fuel growth, support muscle development, and enhance recovery [4,5]. Nutrition has the dual purpose of providing energy to the body and maintaining physiological equilibrium. It also plays a vital function in supporting the metabolism of energy and facilitating the body’s response to exercise-induced stress [6]. Athletes face the challenge of managing oxidative stress, a natural byproduct of cellular metabolism and physical exertion while pursuing peak performance [7]. Oxidative stress arises when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to counteract them with antioxidants [8,9]. While moderate levels of oxidative stress are integral to training adaptations, severe or sustained oxidative stress can cause cellular damage, and inflammation, and hinder recovery [10].

The complex interplay between oxidative stress and antioxidant defense mechanisms highlights the intricate connection between exercise and nutrition [11,12]. Athletes and researchers are acknowledging the growing importance of optimizing nutritional techniques to regulate oxidative stress, which can lead to enhanced performance and reduced risk of overtraining-related issues [13]. An observable pattern in modern sports nutrition is the increasing fascination with diets that mostly consist of plant-based foods [14,15]. Plant-based diets are becoming increasingly popular among athletes due to their potential to supply essential nutrients, enhance recovery, and include a wide range of bioactive compounds [16,17]. These bioactive substances comprise a range of phytochemicals, such as flavonoids, phenolic compounds, carotenoids, and other phytochemicals possessing various properties and are present in fruits, vegetables, nuts, seeds, and whole grains. For example, flavonoids are recognized for their anti-inflammatory and anti-oxidant properties, while phenolic compounds support immunological and cardiovascular health [18,19]. Carotene and lycopene as carotenoids are vital for eye health and may prevent chronic illnesses [20]. Cruciferous vegetable phytochemicals like glucosinolates may prevent cancer [21].

2. Antioxidants: An Overview

2.1. Definition and Types of Antioxidants

Antioxidants play a crucial role in sports and nutrition by protecting against oxidative stress caused by intense physical activity [33]. Antioxidants are chemical substances that combat oxidative stress, a condition that can damage cells. They play a crucial role in maintaining cellular resilience [34,35]. Their crucial function is to counteract free radicals, which are extremely reactive molecules that, if not controlled, can initiate a series of harmful effects on cells [36,37]. As athletes strive to exceed their physical capabilities through intense workouts, understanding the significance of antioxidants becomes crucial [38,39]. These compounds function as molecular barriers, reducing the potential damage caused by free radicals and preserving the cells integrity [40,41]. Various physiological processes can be disrupted and oxidative stress, which is characterized by an imbalance between the body’s capacity to neutralize free radicals and their production, can result in cellular injury. Moreover, it contributes to the development of chronic diseases. Cellular components, including DNA, lipids, and proteins, are susceptible to damage from free radicals, which can result in structural and functional impairments that undermine the health and functionality of the cell [42,43]. Therefore, antioxidants provide an important role in maintaining cellular resilience and improving overall health, especially in individuals involved in strenuous exercise such as sports. To comprehend the complexities of oxidative protection in the realm of sports and nutrition, it is crucial to have a clear understanding of the primary categories of antioxidants (

Athletes, coaches, and nutritionists can use this in-depth look into important antioxidants as a starting point for making dietary selections that support optimal cellular health and performance. A better grasp of nature’s intricate defense mechanisms is made possible by the synergistic effects of these antioxidants, which aid athletes in their pursuit of peak performance.

2.2. Importance of Antioxidants in Human Health

Often disregarded despite their critical importance, antioxidants play a pivotal role in human health [87]. They are crucial to cellular health, resilience, and disease prevention, and their significance extends far beyond basic biochemical events [88,89]. The maintenance of the intricate equilibrium between oxidative stress and antioxidant defense mechanisms within the human body is heavily reliant on the presence of antioxidants [90]. Oxidative stress arises from a disparity between the production of reactive oxygen species (ROS) and the body’s ability to counteract them, which can cause damage to cells, inflammation, and the development of various diseases [8]. Antioxidants serve as protectors, counteracting harmful free radicals and protecting cells against oxidative damage. Cellular resilience is augmented through the facilitation of repair mechanisms, modulation of signaling pathways implicated in inflammation and apoptosis, and preservation of cellular structural integrity [91]. As we delve deeper into their importance, we see that antioxidants are more than just dietary components; they are guardians that navigate the intricate paths of human health [92,93]. Antioxidants promote overall wellness by assisting the body’s capacity to adjust to stimuli and maintain functioning at its optimum level [94]. The nuanced game begins with the body’s natural metabolic processes, which lead to the ongoing production of free radicals. Antioxidants are important because they actively seek for and neutralize free radicals, stopping the potential impact caused by oxidative stress [95]. To keep the fine equilibrium needed for optimal cellular activity, antioxidants function as molecular barriers by destroying free radicals [96,97]. Ensuring the safety of biomolecules and cellular structures is the duty of a sentinel during this process, which goes beyond a simple biochemical transaction.

The narrative gets trickier as we learn about the link between oxidative stress and chronic health conditions. One of the main causes of many chronic diseases is oxidative stress, which occurs when the body’s ability to produce free radicals is not proportional to its capacity to neutralize them [34,98,99]. Heart disease, neurological diseases, and even some cancers have this behavior as their root cause [100,101]. By disrupting this delicate equilibrium, antioxidants offer protection against the progressive worsening of chronic diseases [102]. We highlight the antioxidants’ inherent preventive capacity by investigating this connection. When it comes to cellular health—the basis of overall wellness—antioxidants play a pivotal role [103,104]. Beyond its ability to neutralize free radicals, antioxidants exert a wider range of impacts. The intricate regulation of gene expression [105], cellular communication [106], and DNA repair mechanisms [107], all include their active participation. In addition to coordinating and improving the functioning of cellular processes, their capacity to reduce oxidative stress is a key component of their multifaceted function. In this context, the absence of disease is secondary to the vitality and robustness of individual cells.

2.3. Dietary Sources of Antioxidants

The nutritional aspect plays a crucial role in supporting human health through antioxidants, serving as a fundamental element [108]. The aim is to explore and understand the diverse array of foods that are abundant sources of these essential compounds. The most powerful manifestation of antioxidants is not limited to laboratory formulations, but rather can be found in a wide variety of fruits, vegetables, nuts, and seeds that are often consumed [109,110]. By examining these food sources, we discover not only a compilation of essential nutrients, but also a harmonious blend of culinary elements that promote well health.

As we begin this exploration, it is crucial to acknowledge that antioxidants are not difficult to find and are not limited to specialized superfoods. They are present in the regular foods that make up a balanced diet [111]. Fruits, with their vivid colors, are true repositories [112], berries, including blueberries, strawberries, and raspberries, are notable not only for their pleasant flavor but also for their significant amounts of anthocyanins, a powerful group of antioxidants recognized for their ability to protect against oxidative stress (Figure 1) [113,114]. Vegetables, which are essential for a diet rich in nutrients, make a substantial contribution to the collection of antioxidants [115]. Dark, leafy greens such as spinach and kale contain significant amounts of vitamins A, C, and E, making them powerful friends in the fight against free radicals [116]. Moreover, cruciferous vegetables such as broccoli and brussels sprouts contain a significant amount of sulforaphane, a chemical renowned for its antioxidant and anti-inflammatory properties [117,118].

Nuts and seeds, renowned for their nutritious compositions, enhance the narrative surrounding antioxidants [119]. Almonds, walnuts, and sunflower seeds are rich in vitamin E, while brazil nuts are notable for their selenium concentration, which is an essential trace mineral for the production of antioxidant enzymes [120,121]. The array of antioxidants goes beyond the usual, demonstrating that having a diverse diet is not only enjoyable but also a deliberate way to increase antioxidant consumption [122]. By incorporating foods rich in antioxidants into our diet, it becomes clear that a balanced diet is not just a nutritional recommendation, but also an effective method to increase antioxidant levels [123]. The combination of several foods, each providing its distinct combination of antioxidants, creates a comprehensive method to guarantee sufficient consumption [124]. It emphasizes the significance of having a varied diet, encouraging consumers to explore the wide range of natural foods in order to obtain the complete range of antioxidant benefits [125].

3. Sports and Oxidative Stress

3.1. Introduction to Oxidative Stress in Sports

Within the field of sports science, the dynamic relationship between physical activity and oxidative stress is a captivating narrative that influences how players approach their training, recovery, and overall performance [126]. The aim is to explain the notion of oxidative stress in the context of sports, which acts as a physiological stimulus for adaptation and a possible indicator of injury. In this investigation, we examine the complexities of oxidative stress, analyzing its precise meaning, comprehending its occurrence during physical activity, and acknowledging its ambivalent role as both an ally and adversary in the realm of sports. The core of this investigation is around the understanding that oxidative stress is not a detrimental outcome of physical exertion, but rather a fundamental physiological response that is essential to the adaptive processes triggered by sports training [127]. Oxidative stress, in the context of athletics, refers to an imbalance between the generation of reactive oxygen species (ROS) and the body’s capacity to counteract them via antioxidant defenses (Figure 2) [128,129]. The delicate balance is greatly affected by the intensity, duration, and nature of physical activity, which is essential knowledge for both athletes and sports professionals [86,130].

Oxidative stress occurs in sports when the formation of reactive oxygen species (ROS) exceeds the body’s ability to counteract these molecules, potentially causing damage to cellular structures [130,131]. During vigorous physical exercise, athletes experience an elevation in oxygen consumption, which promotes the production of reactive oxygen species (ROS) [132,133]. The increased level of oxidative stress becomes especially apparent during activities that require substantial aerobic metabolism, underscoring the significance of identifying the precise circumstances in which athletes may be more vulnerable to oxidative stress [134,135].

Sports and exercise are inherently characterized by physical exertion, which serves as a stimulant for the production of ROS [128,136]. The generation of free radicals is a result of muscular contractions, heightened oxygen consumption, and metabolic activities that occur during exercise [137]. Although it may be initially seen as a potential threat, it is crucial to emphasize the dual function of oxidative stress in the field of athletics, which goes beyond its reputation as a simple adversary. Oxidative stress, when examined with a sophisticated perspective, unveils its complex and diverse characteristics. It serves as a signaling system that prompts adaptive responses in the body, leading to enhancements in endurance, strength, and overall performance [138]. However, if the body’s ability to adapt is exceeded by oxidative stress, it can become a possible cause of damage. This can lead to muscle fatigue, inflammation, and in the long run, it may compromise sports well-being [139,140]. Achieving this delicate equilibrium requires a combination of skill and knowledge for athletes and their support teams, emphasizing the importance of customized plans that utilize the beneficial effects of oxidative stress while minimizing its potential disadvantages.

3.2. Mechanisms of Oxidative Stress during Physical Activity

The physiological aspects of sports are greatly affected by oxidative stress, a process that happens during physical exertion [141]. Oxidative stress during exercise is not just a common side effect of exercise, it is a potent factor that determines the adaptive responses in the human body (Figure 2). This inquiry aims to analyze the complex biological mechanisms that generate it [142]. To better comprehend the molecular mechanisms, it is crucial to grasp the origin of oxidative stress, which is closely linked to the generation of reactive oxygen species (ROS) [143,144]. An elevated oxygen demand is associated with physical activity, especially that which involves an increase in aerobic metabolism [145,146]. There are pros and downsides to increasing oxygen consumption, as it results in more reactive oxygen species (ROS) being produced [147,148]. These highly reactive molecules, including free radicals such as superoxide anion and hydroxyl radical, are produced naturally as byproducts of cellular respiration and metabolic activities during physical exercise [149].

The effect of oxidative stress varies significantly and is intimately influenced by the three key factors of exercise: intensity, duration, and type [150]. High-intensity activities, which are known for their demanding requirements on energy systems, frequently result in an increased rate of reactive oxygen species (ROS) formation [151]. Engaging in long periods of physical activity, particularly in endurance sports, increases the amount of time that the body is exposed to oxidative stress, which might potentially amplify its impact [152]. In addition, the specific type of exercise, whether it is aerobic or anaerobic, creates unique metabolic requirements that affect the type and degree of oxidative stress that athletes encounter [153,154].

Mitochondria, commonly recognized as the primary source of energy in cells, are revealed to play a crucial role in the story of oxidative stress [155,156]. Although they function as the principal locations for the formation of reactive oxygen species (ROS), they are also equipped with complex defense mechanisms, including antioxidant enzymes, to ensure cellular balance [157,158]. The intricate equilibrium between the production of reactive oxygen species (ROS) in mitochondria and the protective mechanism against oxidative damage plays a crucial role in influencing the adaptive responses triggered by oxidative stress during physical exercise [159,160]. A potent combination of oxidative stress and inflammation, a normal response to tissue damage or stress, is created in the context of exercise-induced physiological changes [135,161]. Chronic inflammation due to persistent oxidative stress poses risks for athletes, even while minor inflammation is thought of as a typical aspect of the body’s adaptive response [10,162]. The complex mechanisms that control the body’s response to exercise can be better understood by delving into the relationship between oxidative stress and inflammation [163,164].

3.3. Impact of Oxidative Stress on Athletic Performance

Athletes’ abilities are greatly affected by an association between exercise and oxidative stress [165]. Starting with the biological foundations and progressing to the tangible outcomes that influence the sports world, this discussion aims to explore the multiple ways in which oxidative stress impacts an athlete’s performance (Figure 2). Athletes’ performance is significantly impacted by oxidative stress, which is a normal response to intense physical exertion [161,163,166,167]. The effects of this oxidative environment on muscle fatigue and recovery are especially noticeable [168]. Athletes risk muscular fatigue due to the persistent generation of reactive oxygen species (ROS) in their pursuit of peak performance. This has an impact on both the short-term performance and the long-term training adaptations. In order to improve performance, strength, and endurance, athletes have to understand the delicate balancing act between oxidative stress and adaptive responses within muscle fibers [169,170].

The narrative takes on new depths when we consider the intricate relationship between oxidative stress and damage. The capacity of exercise to increase strength and resilience is well-known. But the balance could shift in favor of susceptibility if oxidative stress continues. Potential harm could be increased by oxidative damage to tissues along with the subsequent inflammatory response [171,172]. Acknowledging this potential connection is critical because it encourages athletes and their support staff to take a holistic approach that targets both performance improvement and injury prevention using innovative techniques. When considering the effects of oxidative stress on athletic performance, it becomes clear that there is a requirement for efficient methods to control this physiological reaction [173]. Recognizing that oxidative stress is an inherent component of exercise, the attention turns to utilizing its beneficial elements while minimizing potential disadvantages [174]. In order to more effectively protect themselves against oxidative stress, athletes are encouraged to follow specific dietary protocols that include consuming foods rich in antioxidants [175]. Optimizing training routines, ensuring sufficient recovery, and incorporating sophisticated rest intervals are just as important as diet. A complete strategy that helps athletes perform well under conditions of high exertion and oxidative stress must take these into account [72,162,176,177].

4. The Role of Plants in Sports Nutrition

4.1. Plant-Based Diets for Athletes

Plant-based diets have been a central focus in the constantly changing field of sports nutrition. They are not only a food preference, but a holistic lifestyle approach for athletes [178]. The aim is to explore the idea of plant-based nutrition in the context of sports, which goes beyond conventional dietary boundaries and is increasingly popular among athletes who are looking to achieve peak performance and overall well-being. The core of this investigation revolves around the introduction of plant-based diets, which refer to dietary patterns primarily focused on consuming plant-derived foods. The transition towards a plant-based diet represents a deviation from traditional sports nutrition practices, which frequently give preference to protein sources originating from animals [179]. Athletes are encouraged to adopt a new way of thinking that involves embracing the wide range of plant-based foods, such as fruits, vegetables, whole grains, legumes, nuts, and seeds [180,181,182,183].

Plant-based diets include natural adaptability, allowing for the inclusion of diverse dietary preferences and limits [183]. These variations encompass vegetarianism, which excludes animal products except for dairy and eggs, and veganism, which excludes all animal products [184]. Within this range, athletes may choose to follow a flexitarian strategy, which involves including plant-based meals while not completely eliminating animal products [179]. Appreciating this variety is crucial for comprehending the intricate methods by which athletes manage plant-based nutrition to achieve their distinct performance and dietary objectives.

The popularity of plant-based diets among athletes has experienced significant momentum [14,185,186]. In addition to ethical concerns, athletes are attracted to plant-based diets due to their alleged health advantages, environmental sustainability, and potential to improve athletic performance [187]. Athletes from many sports have enthusiastically adopted plant-based diets, highlighting the practicality and benefits of including more plant-based foods in their conventional training routines [187,188,189]. The potential benefits and drawbacks of athletes switching to plant-based diets are covered in this study. Improving cardiovascular health, speeding up recovery due to plant-based diets’ anti-inflammatory properties, and perhaps better weight control are all benefits [190,191]. Sufficient protein consumption, nutritional shortages, and managing the social and practical demands of a plant-based lifestyle with hard training can be challenging [185].

4.2. Nutrient-Rich Plants for Sports Nutrition

Identifying nutrient-rich plants that are necessary for a balanced diet is a major focus in the area of plant-based nutrition for athletes [186]. Researchers need to find plant-based diets that are high in essential nutrients for peak performance on the field. This aims to emphasize the need of strategic fueling that caters to the specific requirements of sports. However, understanding the nutrient composition of non-plant-based sports diets is equally essential in order to provide athletes with a complete understanding of nutritional options. This comparison reference point may facilitate informed decision-making regarding dietary choices for athletes, considering elements such as nutrient adequacy, performance optimization, and overall health outcomes (Table 2) [192]. Central to this investigation is the focus on particular nutrients acknowledged as crucial elements for athletic performance. Protein, which is essential for the repair and growth of muscles, is of utmost importance [193]. Legumes like lentils and chickpeas, nuts such as almonds and walnuts, and soy products like tofu and tempeh are important sources of protein for athletes [194,195]. This examination of protein obtained from plants not only questions traditional beliefs but also emphasizes the wide range of protein-rich choices accessible to anyone adopting a plant-based diet [196].

Iron, an essential element for the transportation and consumption of oxygen, becomes another topic of emphasis [197]. Spinach, lentils, and fortified cereals are plant-based sources of iron that can help athletes fulfill their iron requirements without depending on conventional animal-derived sources [198]. The narrative transitions from perceived constraints to the ample options that enable athletes to create meals rich in nutrients that are in line with their training objectives.

Calcium, which is crucial for maintaining strong bones and proper muscle function, is found in plant-based sources such as fortified plant milks, leafy greens like kale and bok choy, and tofu made with calcium sulfate [199,200]. This investigation not only questions the traditional story that links calcium solely with dairy, but also emphasizes the flexibility and variability of plant-based sources.

Omega-3 fatty acids, known for their ability to reduce inflammation and promote heart health, are the subject of attention [201,202]. Athletes can get appropriate omega-3 consumption without relying on fish-derived options by consuming plant-based sources such as flaxseeds, chia seeds, hemp seeds, and walnuts [202,203,204,205]. This shift in perspective emphasizes the nutritional knowledge inherent in plant-based diets and their ability to meet the complex requirements of athletes.

The main message goes beyond listing nutrient-rich plants—it emphasizes the significance of a well-balanced plant-based diet as a strategic approach to fulfill nutritional requirements. This nutritional approach not only debunks misconceptions about nutrient inadequacies but also promotes the concept that a thoughtfully chosen assortment of plant-based foods may provide athletes with a strong basis for achieving peak performance.

4.3. Plant Compounds and Their Potential Benefits in Sports

Further investigating the connection between plant-based nutrition and athletic performance, the analysis extends to include the diverse range of bioactive chemicals naturally found in plants [226]. The aim is to explore the potential advantages of plant compounds for athletes, by shifting the attention from just the nutritional value to the complex network of phytochemicals, antioxidants, and anti-inflammatory compounds. These elements contribute to improved recovery and resilience in the field of sports. The main focus of this investigation is the examination of phytochemicals, which are plant components that provide health benefits beyond basic nutrients [227]. Athletes, in their pursuit of peak performance, may discover valuable support in these bioactive substances [228]. Phytochemicals, specifically flavonoids present in berries, citrus fruits, and tea, have been linked to anti-inflammatory and antioxidant characteristics [180,229]. Berries like strawberries and blueberries, for example, include flavonoids called anthocyanins and flavonols that have been associated with potent antioxidant effects [230]. Similarly,, flavonoids found in citrus fruits like oranges and lemons, such as hesperidin and naringenin, have anti-inflammatory properties and contribute to overall health [231]. Furthermore, catechins like epigallocatechin gallate (EGCG), which are well-known for their anti-inflammatory and antioxidant properties, are rich in tea, especially green tea [232]. This discovery broadens the range of tools available to athletes, going beyond traditional nutrition, and encouraging them to utilize the potential advantages of these substances produced from plants. Antioxidants, highly regarded for their capacity to counteract free radicals and address oxidative stress, are recognized as significant contributors in the discussion surrounding plant compounds [233]. Athletes who are facing the challenges of rigorous training might seek assistance from plant-based foods that are rich in antioxidants, such as vibrant fruits and vegetables, as well as nuts and seeds [14,234]. The study goes beyond simply listing antioxidants and delves into a detailed examination of how these substances can impact an athlete’s physiological environment, perhaps improving recovery and strengthening the body against the demands of training.

The presence of anti-inflammatory substances in plant-based diets is crucial in the field of sports nutrition [235]. The primary cause of the diet’s anti-inflammatory effects is the presence of nutrients and bioactive compounds that alter the body’s inflammatory pathways. For example, certain antioxidants found in plant-based diets, such as polyphenols and flavonoids, can prevent the production of pro-inflammatory cytokines including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) [236,237]. Furthermore, by competing with omega-6 fatty acids for enzymatic conversion into pro-inflammatory eicosanoids, omega-3 fatty acids—which are abundant in foods like flaxseeds, walnuts, and fatty fish—execute anti-inflammatory effects [238]. Additionally, eating a diet high in fiber, such as fruits, vegetables, and whole grains, encourages the growth of beneficial gut bacteria which produce short-chain fatty acids that help regulate immune responses and reduce inflammation [239]. The innate inflammatory response elicited by physical activity is an integral aspect of adaptation, however, persistent inflammation presents hazards to athletes [240]. The narrative emphasizes the presence of plant chemicals, such as curcumin in turmeric, quercetin in onions and apples, and resveratrol in grapes, which are known for their potential anti-inflammatory properties [241,242]. Athletes are encouraged to view these substances not only as supplements, but also as essential elements of a comprehensive strategy for reducing inflammation and enhancing recovery.

The narrative goes beyond the biochemical aspects to discuss the physiological consequences that athletes should expect, using specific plant chemicals as examples [243,244]. Resveratrol, which is present in red grapes, has been linked to better cardiovascular health and increased endurance [245]. The narrative presented here surpasses the reductionist perspective, encouraging athletes to not only focus on the nutritional value, but also to recognize the comprehensive advantages inherent in the wide range of plant chemicals. The focal topic of this investigation is the examination of how plant chemicals can potentially enhance recovery and resilience. The narrative invites athletes to consider plant-based nutrition as more than just a dietary choice, but as a comprehensive strategy that strengthens the body against oxidative stress, promotes anti-inflammatory responses, and enhances general resilience in the face of athletic obstacles.

5. Antioxidants in Plant-Based Foods

5.1. Overview of Antioxidants in Plants

The narrative that emerges from looking into the antioxidant content of plant-based diets extends beyond the usual nutrition debates [74]. The goal is to get individuals to pay attention to the wide variety of antioxidants that plants contain. Collectively, these antioxidants enhance overall health like a symphony of defensive mechanisms (Figure 3). The examination of antioxidants in plants offers a comprehensive exploration of the diverse array of phytonutrients, each fulfilling a unique function in enhancing well-being [246]. Plants contain a variety of antioxidants, such as flavonoids in berries and carotenoids in colorful vegetables, that go beyond the usual nutrient classifications [180,247,248]. In its complex web of effects, plant-based diets involve a wide variety of chemicals, and this study casts emphasis on the idea of a single antioxidant hero.

Highlighting the wide range of antioxidants present in plants is crucial for changing the way we think about consuming antioxidants (Table 3) [249]. The conventional method frequently focuses on a limited number of well-established antioxidants, but the plant-based viewpoint expands the scope to include other lesser-known yet equally powerful antioxidants [250]. This variety encourages athletes to explore a diverse and vibrant range of plant-based foods, each providing its own combination of antioxidants to promote overall health (Figure 3).

This study explores and explains the differences in the functioning of antioxidants obtained from plant sources compared to those obtained from other dietary sources [248]. Although antioxidants obtained from supplements or animal-derived sources have a role to play, the distinct bioavailability and synergistic interactions shown in plant-based antioxidants provide a strong argument [196]. Plant-derived bioactive compounds frequently demonstrate a range of functions, such as anti-inflammatory and anti-cancer capabilities. These chemicals provide athletes with a comprehensive approach to supporting their health, which goes beyond the conventional antioxidant concept [251]. The core focus is on the synergy between various antioxidants found in plant-based meals, highlighting that their cumulative impact is more significant than the individual chemicals alone [252]. The study goes beyond simplistic viewpoints, encouraging athletes to perceive their dietary choices not as separate decisions but as contributions to a balanced symphony of health-enhancing chemicals [228,252]. This comprehensive approach encourages athletes to embrace the combined advantages inherent in entire, plant-based meals, acknowledging that the total effect is higher than the individual antioxidant components [175,178].

5.2. Specific Antioxidants Found in Common Plant Foods

In order to comprehend the vast array of health-promoting compounds contained in staple plant foods including fruits, vegetables, grains, and legumes, it is necessary to do in-depth research on the specific antioxidants present in these meals. We delve into the complex understanding of antioxidants, their potential health benefits, and the wide range of antioxidant profiles found in different plant-based sources, going beyond just listing them. Within the domain of fruits, the array of antioxidants is extensive and varied [112]. Vitamin C, which is plentiful in citrus fruits, strawberries, and kiwi, is a powerful antioxidant that enhances the immune system [111,182]. Additionally, the anthocyanins included in berries, such as blueberries and raspberries, provide both their vivid colors and valuable properties that reduce inflammation and protect the nervous system [267,268]. In addition to common antioxidants, the narrative delves into less well-known compounds, including the apple quercetin and grape resveratrol, which each have their own unique health benefits [269,270].

Vegetables, which are essential for a diet rich in nutrients, provide a wide variety of antioxidants [181,271,272]. Carotenoids, such as beta-carotene found in carrots and sweet potatoes, lutein present in spinach, and lycopene found in tomatoes, demonstrate the wide range of antioxidants present in this food group [273,274]. These chemicals have multiple benefits, including enhancing pigmentation and playing important roles in maintaining eye health, protecting the skin, and promoting cardiovascular well-being [275]. Furthermore, cruciferous vegetables, such as broccoli and brussels sprouts, provide sulforaphane to the collection of antioxidants, which may provide anti-cancer advantages [276,277].

Grains, which are sometimes undervalued for their antioxidant content, offer a captivating variety of chemicals [278,279]. The phenolic acids present in whole grains, such as oats and brown rice, have antioxidant and anti-inflammatory properties [278,280]. Flavonoids, commonly found in fruits, also have a positive impact on grains such as buckwheat and quinoa, providing a wide range of health advantages [281,282]. This discovery challenges the traditional belief that antioxidants are only found in colored fruits and vegetables. It encourages athletes to recognize the nutritional value present in whole grains.

Legumes, which are known for their high protein content in plant-based diets, also serve as sources of antioxidants [183,283]. Soybeans include isoflavones, which have both hormonal balancing effects and antioxidant capabilities [284,285]. In addition, the polyphenols found in lentils and chickpeas enhance the antioxidant activity in legumes, providing a diverse and comprehensive approach to promoting health [286,287]. This narrative goes beyond the protein-focused perspective on legumes, urging athletes to acknowledge the comprehensive nutritional benefits of these plant-based sources of strength.

An essential aspect of our investigation involves providing detailed information about the potential health advantages linked to each antioxidant. Vitamin E, present in nuts and seeds, acts as an antioxidant and promotes skin health and immunological function [58,288]. The catechins included in green tea, which is made from the leaves of the Camellia sinensis plant, contribute to antioxidant and anti-inflammatory actions, potentially improving cardiovascular health [289,290]. Displaying the range of antioxidant compositions in various plant-based diets offers a visually engaging exploration of the wide spectrum of nutritional variations. The colors of berries, leafy vegetables, and turmeric represent different antioxidants, each with its own specific health benefits [1,31,190,228].

5.3. Synergistic Effects of Antioxidants in Plants

To better understand the intricate relationship between various plant antioxidants and how they synergistically boost each other’s efficacy, research into plant-based nutrition has focused on the concept of antioxidant synergy (Figure 4). Beyond the conventional understanding of antioxidants in isolation, this study explores the complex interplay between plant-based diets and antioxidants, to determine the latter’s role in athletic health and performance. The idea of synergy among plant antioxidants is shown as a story that goes beyond the combined effect of each individual antioxidant [291]. The complex network of phytonutrients found in plant meals, each with its distinct antioxidant composition, work together in a coordinated manner to enhance the total antioxidant impact [292]. This interdependent interaction challenges simplistic viewpoints, encouraging athletes to perceive their food decisions not solely as suppliers of individual components, but rather as coordinated arrangements that promote good health.

The narrative is centered on explaining how antioxidants in plants can work together. Vitamin C and flavonoids, which are present in many fruits and vegetables, have a synergistic effect when taken together. A number of flavonoids have their bioavailability enhanced by vitamin C because of its tendency to increase absorption [293,294]. Beyond the obvious nutritional benefits, there is an intricate network of processes that allows athletes to get a variety of antioxidant benefits from plant-based diets. Illustrating instances of antioxidant synergy in particular plant-based meals vividly demonstrates this principle (Figure 4). When leafy greens, which are high in carotenoids, are combined with tomatoes, which are rich in vitamin C and lycopene, the resulting meal visually demonstrates the concept of antioxidant synergy [108,295]. The complex equilibrium present in this meal not only provides a wide range of antioxidants but also likely enhances their combined effect. Athletes are advised to carefully select meals that highlight this harmonious combination, acknowledging that the colors and flavors on their plate represent more than just visual appeal—they represent a deliberate strategy to enhance health and performance [296].

The vital impact of antioxidant synergy on overall health and performance is the primary foci of this study. It is recommended that athletes think about the quality as well as the quantity of antioxidants in their meals [175]. A complete diet rich in plant-based foods such fruits, vegetables, grains, and legumes is the best way to take advantage of antioxidants in their whole form [196,297]. The narrative challenges the idea that antioxidants may be easily substituted for one another and emphasizes the significance of recognizing the intricacies present in plant-based meals for achieving overall health optimization [298].

6. Practical Applications for Athletes

6.1. Incorporating Plant-Based Foods into Athletes’ Diets

Athletes need an organized strategy to incorporate plant-based nutrition into their meals [179]. The goal of these suggestions is to provide athletes with easy-to-implement instructions that they may incorporate into their dietary plans. An increase in variety, a focus on high nutritional content, and customization for different sports and training stages are the main goals. Protein should come from a variety of sources, according to the plant-based diet guidelines [178]. Diverse plant-based protein sources, such as edamame, lentils, beans, and tofu, are recommended for athletes [186]. Ensuring a comprehensive amino acid composition is the goal, as it maximizes the process of protein synthesis. Athletes are encouraged to focus on plant-based options that are minimally processed, including fruits, vegetables, whole grains, nuts, and seeds, by highlighting the importance of whole foods. Optimal nutrition consumption and improved health are the goals of this approach, which aims to reduce reliance on processed foods. It is the goal of meal planning strategies to strike a balance between nutrient density and nutritional balance. For optimal energy during training and recovery, athletes should aim to eat a balanced diet that includes carbs, proteins, and fats (the “macros”) [299]. The aesthetic value of the dish is elevated, and the variety of phytonutrients and antioxidants provided by the fruits and vegetables is assured, by using a diversified selection of these ingredients [300]. Energy levels and muscle recovery are affected by the timing of food intake, which is why this factor is given special attention when discussing exercise sessions [301]. When thinking about different sports and training times, specific dietary considerations come up [302]. Endurance athletes should fuel their lengthy training sessions with carbohydrate-rich plant foods [2]. A diet rich in iron and vitamin C is crucial for endurance athletes since their bodies need more iron than the average person [303]. On the contrary, athletes who put an emphasis on strength and power use plant-based protein sources to help with recovery and protein synthesis in the muscles. Because omega-3 fatty acids may have strong anti-inflammatory effects, they also highlight the need of eating foods high in these nutrients [304]. Nutrient intake should be structured to coincide with different training stages, and calorie consumption should be adjusted according to the quantity of training.

6.2. Developing Antioxidant-Rich Meal Plans for Training and Recovery

In order to help athletes in their training and recovery, this section provides customized meal plans (Table 4) that are high in antioxidants and made to fit their nutritional demands. Primarily, the content is devoted to offering sample antioxidant-rich meal plans that are designed for pre-training, post-training, and recovery phases. In addition, taking into account the different needs of athletes, the factors also include adjusting to changes based on personal dietary preferences and limitations. Recognizing the pivotal role that time and composition play in achieving optimal results, the study emphasizes their critical importance.

During the pre-training period, it is advised to follow a meal plan that focuses on providing a well-balanced combination of macronutrients to provide a consistent supply of energy during the impending physical activity [305,306]. A deliberate integration of intricate carbs, lean proteins, and nourishing fats is tactically implemented. Athletes can derive advantages from ingesting foods that are rich in antioxidants, such as berries, almonds, and leafy greens, during this phase. This helps to promote cellular health and establish a solid nutritional base for the impending activity [234,307].

Post-training meal regimens prioritize effective recovery by focusing on replenishing glycogen stores and promoting muscle regeneration [308]. The focus here is on maintaining a balanced consumption of carbs and proteins, with a significant role being played by components that are rich in antioxidants [309]. Consuming fruits that are rich in vitamin C, such as citrus fruits or kiwi, might help decrease oxidative stress [310,311]. Additionally, including plant-based protein sources like beans or tofu in diet guarantees a well-rounded dietary profile that supports recovery [312].

The recovery phase highlights the need of restoring energy reserves and promoting muscle restoration [313]. The meal plan suggests incorporating a blend of carbohydrates and proteins, while also emphasizing the use of anti-inflammatory foods [314,315]. Adding vibrant vegetables such as bell peppers and tomatoes, which are recognized for their antioxidant capabilities, is crucial in reducing inflammation caused by exercise [316]. Customizing these regimens to suit individual nutritional preferences guarantees that athletes may follow the guidelines while meeting their distinct likes and limitations.

Within these suggestions, the study continuously highlights the crucial elements of timing and composition. Consuming these meals rich in antioxidants at the appropriate time corresponds to the distinct requirements of each phase, be it preparing the body for physical activity, aiding in recuperation, or enhancing cellular health during periods of rest [309]. The meal plans are carefully designed to incorporate a balanced combination of macronutrients and micronutrients, acknowledging that the interaction between these components enhances the overall efficacy of the dietary approach [317].

To address the requirement for quick recuperation between periods of physical activity, it may be necessary to strategically consume foods that are rich in antioxidants in order to alleviate oxidative stress [365,366].

Given the acknowledgement that a single approach is not suitable for everyone, it becomes crucial to provide practical guidance on how to adjust plant-based nutrition to various sports situations [367]. Athletes are advised to explore various plant-based sources, modify macronutrient ratios according to different training phases, and take into account individual preferences and tolerances [189]. The adaptability of the guidelines guarantees that they are in line with the specific requirements of each sport and the distinct physiological reactions of individual athletes [367].

7. Challenges and Limitations

Examining the nuances of plant-based diets in sports reveals significant benefits as well as challenges for athletes considering adopting this nutritional approach. The primary areas of concern for athletes aiming for peak performance—maintaining energy balance, protein consumption, and dietary deficiencies—are discussed in relation to the possible downsides. Because of misconceptions regarding its availability in plant sources, protein—which is frequently emphasized for its vital role in muscle growth and recovery—poses a problem to those following plant-based diets. However, research shows that when included in a diversified and well-planned diet, plant-based proteins like those found in beans, quinoa, and soy products are sufficient to meet the protein requirements of athletes. Another issue covered in the study is nutritional deficits, specifically in the areas of vitamins B12, iron, calcium, and omega-3 fatty acids. It recommends a varied plant-based diet and fortified meals and supplements as practical ways to make sure athletes are not compromising on vital nutrients. Achieving the right energy intake is also essential, particularly in light of the high calorie requirements of sports training and competition. Incorporating foods high in energy from plants and carefully planning meal compositions to support nutrient balance and energy requirements are two strategies for overcoming these challenges.

Challenges with antioxidant supplements in sports nutrition are also explored in the story (Figure 5). Although antioxidants play a crucial role in preventing oxidative stress caused by strenuous exercise, there are risks associated with using supplements rather than obtaining them from whole foods, such as overconsumption and nutritional imbalances. A diet rich in fruits, vegetables, nuts, and seeds is the most effective way to absorb antioxidants, according to the report, because they work synergistically and are more bioavailable. In addition to addressing the limitations and potential risks of supplement reliance, this approach promotes the idea that athletes should prioritize the complexity of dietary matrices above the use of isolated nutritional supplements. Although the study highlights the value of whole foods in providing a balanced array of antioxidants and other micronutrients necessary for optimal health and athletic performance, the ongoing debate over the effectiveness of antioxidant supplements in improving performance and recovery adds another layer of complexity to the matter.

The discussion emphasizes the need for more scientific studies to address current gaps in the field of sports nutrition, plant-based diets, and antioxidants. Although progress has been made in recognizing the advantages of plant-based nutrition for athletes, there are still unexplored areas, such as the specific mechanisms by which plant chemicals affect performance and the lasting impacts of these diets in various sports. The narrative suggests that future study should investigate the precise effects of phytochemicals and antioxidants found in plant-based meals on athletic performance and recovery. Future research should prioritize customized nutritional approaches that take into account the varied requirements of different sports, training levels, and individual athlete needs. The goal is to improve plant-based nutrition strategies to help athletes reach their performance goals and preserve their health and well-being. In sum, plant-based diets can be a beneficial nutritional approach for athletes, but it is crucial to address the problems related to protein consumption, vitamin shortages, and energy equilibrium. Prioritizing whole foods for antioxidants and advocating for more research to address knowledge gaps highlights a sophisticated approach to sports nutrition that focuses on evidence-based dietary planning.
