This review examines the relationship between tennis participation and mental health, highlighting both the psychological benefits and challenges associated with the sport. Using a retrospective, citation-based methodology, peer-reviewed studies published in English, French, and Greek between 2000 and March 2025 were included. The findings indicate that tennis participation is associated with reductions in depressive and anxiety symptoms, improved self-confidence, and enhanced resilience. However, competitive tennis also presents significant psychological demands, including elevated stress levels and susceptibility to maladaptive coping behaviors. To address these complexities, this review introduces the Resilience Racket Model, a conceptual framework representing the integration of physical readiness, psychological resilience, and systemic support. The model uses the metaphor of a tennis racket: the handle reflects foundational physical skills; the strings represent resilience components; the frame denotes environmental and organizational support; and the sweet spot signifies the optimal balance between physical and mental readiness. The review also highlights the effectiveness of psychological interventions, such as cognitive-behavioral therapy and mindfulness, in supporting athlete well-being. These findings advocate for a holistic approach to athlete development, emphasizing parity between mental health and physical training, and call for further research into tailored, sport-specific mental health interventions in tennis.

One of the physical requirements for marines involves covering a specific distance while carrying individual combat gear, supplies, or other military equipment across challenging terrain. Training for this physically and mentally demanding task is a routine component of their preparation. However, further research is needed to better understand the neuromuscular impact of such demanding efforts, strenuous maneuvers, and the recovery process in the subsequent days. Twenty-nine marines completed a 5 km time trial while carrying 24 kg of combat gear, undergoing evaluations at four time points: pre exercise, immediately post exercise, 24 h post exercise, and 48 h post exercise. Repeated measures ANOVA, paired samples t-test, and effect size (ES) analysis were conducted, presenting the results as the mean ± standard deviation (SD). The significance level was set at p ≤ 0.05. Several variables and their corresponding p-values demonstrated changes over time, including the following: the isometric mid-thigh pull (IMTP) (p = 0.001); countermovement jump height (VJ CMJ) (p ≤ 0.001); rating of fatigue scale (ROF) (p ≤ 0.001); blood lactate (BL) levels (p ≤ 0.001); maximum pull-ups (PUmax) (p ≤ 0.001); body mass (BM) (p ≤ 0.001); dominant hand grip strength (DHGS) (p = 0.406); and non-dominant hand grip strength (NDHGS) (p = 0.805). Incident reports and perceived effort (IRPE) revealed a progressive and significant increase between the first and last kilometer of the test, specifically in perceived variables of fatigue, muscle pain, joint pain, shortness of breath, palpitations, excessive sweating, and muscle tremors (all p ≤ 0.001). These findings may contribute to optimizing training programs to better align with operational demands, thereby improving task performance and overall mission effectiveness. In conclusion, the military test had a significant neuromuscular impact on the body, initially resulting in the potentiation of absolute global isometric strength and lower-limb power. However, these values declined below the baseline levels at 24 and 48 h post test.

Military schools primarily aim to prepare young people for the admission procedures of military academies. In this specific environment, the high overall load can generate burnout in cadets and the consequent failure to achieve scholastic and military objectives. The present study investigated how a training protocol based entirely on internal load and a reflective approach in a military-type school context affects participants’ physical efficacy, efficiency, and psychological outcomes. For this study, 63 cadets who were 17 years old from an Italian military school were recruited. Twenty-two of them were allocated into a control group (CG), twenty-one were allocated into a group exercising based on external load (EG), and twenty we allocated into a group exercising based on internal load (IG). All groups performed tests of physical efficacy (maximal tests) and physical efficiency (self-perception-based submaximal test) and answered psychological questionnaires to assess motivation, self-efficacy, and enjoyment. Group participants attended eight weeks of interventions in which physical education lessons were led as follows: the EG performed a circuit training at 50% of maximal repetitions, the IG performed a circuit training at value six on Borg’s scale, and the CG attended curricular physical education lessons. Tests were then repeated. The IG increased physical efficacy more than the EG and CG, while only the IG increased physical efficiency. The IG and EG improved in psychological variables more than the CG. Education in self-perception and self-regulation could help cadets better manage their psychophysical status, allowing them to reach the physical demands for academic admission.

Background: In sports and physical activities, destructive behaviors such as aggression and violence are not uncommon. Although sports and physical activities have many benefits, they can also have negative consequences. This study aimed to investigate the factors that can contribute to the manifestation of aggression and interpersonal violence (IV). The variables incorporated were the athletes’ age, sports experience (training years), and type of sport. Methods: This study included n = 2091 youth athletes (aged between 11 and 18 years) from Serbia, with a cross-sectional study design. The data were collected through a questionnaire and analyzed using the Chi-square and Mann–Whitney U tests in IBM SPSS. Results: The athletes’ ages and the types of sports (collective and contact) in which they participated are associated with aggression and IV manifestation. In addition, physical violence tends to be more common among older athletes in collective and contact sports, while psychological violence is more prevalent among older athletes who train for five or more years and participate in collective and non-contact sports. Conclusions: Identifying some of the correlated factors in aggression and IV manifestation among youth athletes could help in the development of strategies to reduce these destructive behaviors in youth sports.

The professionalization of futsal requires greater physical demands on players, requiring strength and conditioning coaches to manage loads, optimize performance, and prevent injuries. This study aimed to describe the current practices of high-level strength and conditioning coaches and determine the elements needed to optimize their performance. Two video-recorded focus groups consisting of eight strength and conditioning coaches from the Spanish futsal league’s first and second divisions were transcribed, translated, and analyzed using a content analysis approach with open-ended questions on physical preparation and current practices. Results showed that strength and conditioning coaches prioritized five main areas: (1) competitive demands, (2) training load control and monitoring, (3) injury risk mitigation strategies, (4) contextual factors and interpersonal relationships, and (5) training methodologies to optimize performance. However, they also claim to deal with several limitations such as lack of time, limited resources and access to facilities, insufficient staff, problems related to combining sport with other activities (e.g., work), or the difficulty to individualize, which limits the optimization of their practices. Based on these findings, practical applications include implementing neuromuscular and strength training sessions at least twice a week, using cost-effective load monitoring tools (e.g., RPE and wellness questionnaires) to manage workloads, individualizing training programs to address the specific demands and characteristics of each player, and fostering close multidisciplinary collaboration to optimize performance and reduce injury risks. These insights can guide current and aspiring strength and conditioning coaches toward optimized practices. This study can assist novice strength and conditioning coaches in identifying the key focus areas of elite physical trainers and understanding their challenges and limitations, fostering collaboration among sports professionals to create a more optimized environment.

Background: Motivation is a crucial factor in maintaining athletic performance and preventing dropout among competitive athletes. This process is influenced by both physical and psychosocial factors, which interact and shape decision—making regarding continued participation or withdrawal from sports. Aim: This study examines the motivational level of competitive swimmers in Romania, related to the dropout perspective. Methods: In order to conduct the research, the AMI (Achievement Motivation Inventory)—a validated psychometric tool was used in two distinct phases, conducted six months apart. The study included N = 20 swimmers, finalists and medalists in national swimming competitions. The intervention consisted of motivational coaching, personalized training plans, and the development of mental skills. Results: The results highlighted significant improvements in dimensions such as success confidence, compensatory effort, and goal-setting, indicating the positive effects of the intervention on athletes’ motivation. Inferential analysis using Student t-test confirmed significant differences between the initial and final assessments, for eagerness to learn (p = 0.035), status orientation (p = 0.03) and the Wilcoxon test revealed significant difference for general motivational index (p = 0.020). Conclusions: The findings underscore the importance of psychological approaches in training high-performance athletes, showing that maintaining motivation and clarifying goals are essential factors in preventing sports dropout. The conclusions of this research can serve as a foundation for developing coaching strategies aimed at supporting continuity in performance swimming and reducing the dropout rate among competitive swimmers. Our findings confirm similar studies emphasizing the role of the training patterns and coach influence not just on the performing athlete, but also on his psychosocial individual development.

Background: The overweight population is a major public health problem which is typical for the 21st century, considering the peak of the noncommunicable diseases (NCDs). The connection between hypertension—the number-one risk factor of cardiovascular diseases (CVDs)—and the body mass index (BMI), which is growing worldwide, needs to be taken into consideration. Methods: Four homogeneous groups of twenty-five patients each with hypertension degree 1 benefited from different 8-week recovery programs: recommendation for a healthy lifestyle (all groups—A, B, C and D), antihypertensive medication (groups B, C and D), physical therapy program (group C), and hydrotherapy program (group D). Four parameters were pursued: body mass index (BMI), waist circumference (Wcir.), and systolic and diastolic blood pressure (SBP-DBP). Results: Intragroup comparison between initial and final testing registered a statistically significant decrease in all parameters for group C: BMI (p = 0.001), Wcir, SBP and DBP (p < 0.0001). Additionally, parameters of group D decreased significantly: BMI (p = 0.0005), Wcir, SBP and DBP (each p < 0.0001). Group A registered a statistical increase in the DPB parameter (p = 0.03), and group B had a significant decrease in SBP (p = 0.03). Conclusions: Implication in established physical therapy and hydrotherapy had a better outcome in diminishing all four parameters compared to the recommendations for a healthy lifestyle when patients had to improve their lifestyle by themselves, unsupervised.

Executive functions are often impaired in individuals with schizophrenia spectrum disorders. Understanding the impact of physical exercise on these cognitive domains is essential for developing effective interventions. The aim of this review is to assess the effect of physical exercise on executive functions in adults diagnosed with schizophrenia spectrum disorders. A systematic search was conducted in Web of Science, PubMed, Scopus, and EBSCO, initially from inception through January 2024, followed by an update through January 2025. Studies involved adults diagnosed with schizophrenia spectrum disorders, employed physical exercise as an intervention, and measured executive functions as outcomes. The selection followed PRISMA guidelines, with inclusion determined by consensus among multiple reviewers. Data extraction and risk of bias assessment were conducted independently by two reviewers using the Cochrane RoB 2 tool and GRADE approach for certainty of evidence. Meta-analyses were performed using random-effects models, with effect sizes (ES) and 95% confidence intervals (CI) calculated for each outcome. From 1517 records, 9 studies were included in the meta-analysis. The analysis revealed a small but significant effect of physical exercise on working memory (ES = 0.300, 95% CI = 0.060–0.539, p = 0.014; I2 = 0.0%, Q = 2.2, p = 0.951) and a non-significant effect on emotion recognition (ES = 0.51, 95% CI = −0.291–1.303, p = 0.213; I2 = 83%), inhibition (ES = 0.156, 95% CI = −0.173 to 0.484, p = 0.353; I2 = 0.0%, Q = 1.1, p = 0.781), and cognitive flexibility (ES = 0.240, 95% CI = −0.270 to 0.749, 95% PI = −1.706 to 2.185; p = 0.356; I2 = 53.2%, Q = 3.0, p = 0.094). Physical exercise, particularly aerobic exercise, appears to have a small beneficial effect on working memory in individuals with schizophrenia spectrum disorders. However, the evidence for its effect on emotion recognition is less clear and may be influenced by the type of exercise, such as yoga. Further research is needed to provide more robust conclusions. PROSPERO registration number: CRD42023392295.

This study analyzes and compares sports supplement (SS) consumption among federated road cyclists, considering sex and competition category. The aim is to identify key factors influencing SS use and provide insights for developing nutritional strategies in cycling. A cross-sectional, descriptive study was conducted, involving 1503 cyclists (1231 men and 272 women). Data were collected through a validated questionnaire assessing anthropometric data, training habits, SS consumption patterns, and sources of information. Results indicate that 64.3% of cyclists currently use SS. Women reported a significantly higher consumption rate (88.2%) compared to men (59.1%), although men had a higher average SS intake than women (8.28 ± 9.36 vs. 6.76 ± 5.96). Additionally, SS use decreased with age and competition level, with elite cyclists showing the highest prevalence (76.3%) and master 50 the lowest (58.4%). Group A supplements (scientifically supported) were the most frequently used, while Group C supplements (limited evidence) and Group D substances (prohibited) were more commonly consumed by men. Findings highlight significant differences in SS consumption based on sex and competition level, with elite cyclists and women reporting higher prevalence. However, men reported a higher average number of SS consumed. The study underscores the need for targeted nutritional education, particularly among master cyclists, to promote evidence-based SS use and minimize the risks of ineffective or unsafe supplementation. Future research should explore the long-term effects of SS consumption in cycling and the effectiveness of educational interventions for safe and optimized supplementation practices.

(1) Background: The range of loads is defined as the difference between the highest and the lowest relative load (i.e., %1RM) used throughout a resistance training program. However, the optimal range of loads has not been studied yet. Thus, the aim of this study was to compare the effects of different ranges of load (from 50 to 85% 1RM (R50–85), from 55 to 75% 1RM (R55–75), and from 60 to 70% 1RM (R60–70) on physical performance using velocity-based resistance training (VBT). (2) Methods: Thirty-eight men (mean ± standard deviation; age: 23.3 ± 3.6 years, body mass: 76.5 ± 8.3 kg, and height: 1.77 ± 0.04 m) were randomly assigned to R50–85, R55–75 and R60–70 groups and followed an 8-week VBT intervention using the full squat (SQ) exercise. All groups trained with similar mean relative intensity (65% 1RM) and total volume (240 repetitions). Pre- and post-training measurements included the following: in the SQ exercise, 1RM load, the average velocity attained for all absolute loads common to pre-tests and post-tests (AV), and the average velocity for those loads that were moved faster (AV > 1) and slower (AV < 1) than 1 m·s−1 at Pre-training tests. Moreover, countermovement jump (CMJ) height and 10 m (T10), 20 m (T20), and 10–20 m (T10–20) running sprint times were measured. (3) Results: Significant group x time interactions were observed in AV (p ≤ 0.01), where R50–85 obtained significantly greater gains than R60–70 (p ≤ 0.05). All groups attained significant increases in 1RM, AV, AV > 1, AV < 1, and CMJ (p ≤ 0.001–0.005). Significant improvements were observed in running sprint for R60–70 in T10–20 and R60–70 in T20 and T10–20 (p ≤ 0.05), but not for R50–85. (4) Conclusions: Different ranges of loads induce distinct strength adaptions. Greater ranges of loads resulted in greater strength gains in the entire load-velocity spectrum. However, in high-velocity actions, such as sprinting, significant enhancements were observed only for smaller ranges of loads. Coaches and strength and conditioning professionals could use a range of loads according to the time-related criterion (i.e., proximity or number of future competitions), enabling better adaptation and increasing physical performance at a specific time.

This study investigated the causes of incorrect judgments in a motor task and examined differences between students with varying levels of judgment accuracy. Twenty-two seventh graders participated. Based on their estimated and actual scores in two volleyball serve trials, students were categorized into two groups: “low accuracy” and “high accuracy”. Before each trial, they estimated their scores according to the American Alliance for Health, Physical Education, Recreation, and Dance test. Following the trials, students were interviewed about their justifications and their confidence in the accuracy of their judgments. Independent sample t-tests indicated that both “low accuracy” and “high accuracy” students appeared to use metacognitive skills (t(20) = 0.82, p > 0.05). However, the “low accuracy” group lacked the declarative and procedural knowledge (t(20) = 4.59, p < 0.001) necessary for accurately evaluating their performance. Findings suggest that students focused more on outcome-based rather than process-based assessments when evaluating their performance. Enhancing students’ access to both theoretical and experience-based cues in sports may improve their ability to accurately judge their performances and foster greater confidence in lifelong participation in physical activities.

Young adults, especially students, face challenges that increase social anxiety, including Social Physique Anxiety (SPA). The objective of the present study was to examine SPA among college students across various study programs and explore its associations with exercise, physical self-perception, and self-esteem. A total of 465 students, with an average age of 21.3 years, completed the Social Physique Anxiety Scale, Rosenberg Self-Esteem Scale, and Physical Self-Perception Profile. Demographic information and exercise habits were also collected. The findings indicated that the subject of study was not associated with SPA, regardless of gender. Multiple regression analysis identified physical self-worth, self-esteem, and gender as variables associated with SPA among study groups. Higher levels of physical self-worth and self-esteem were linked to lower SPA levels, and gender had a significant association with SPA. These findings suggest that global and physical self-esteem may play important roles in SPA among college students. Promoting regular physical activity and fostering positive physical self-perception among college students, particularly females, could be beneficial in addressing SPA.

Environmental temperature (Te) is a main atmospheric parameter that may affect the physical and physiological demands of outdoor sports. Thus, this study aimed to examine the relationship of Te with the physical and physiological demands of beach soccer match-play. Physical and physiological demands were collected from 60 male players during Portuguese elite beach soccer championship matches using a 10 Hz wearable global positioning system, heart rate, and the rate of perceived exertion (RPE). A bilateral counter-movement jump (CMJ) test assessed lower limb power performance before and immediately after the match. Fluid loss was determined by body mass weighing before and after the end of the match. Te and wet-bulb globe temperature (WBGT) parameters were continuously recorded. The matches occurred across Te ranging from ~20.0 °C to 43.0 °C. Physical demands, CMJ height, peak heart rate (HRpeak), mean heart rate (HRmean), and RPE were not correlated with Te. However, a significant correlation was found between fluid loss and Te (r [95% CIs] = 0.67 [0.43–0.75]; p < 0.001). Beach soccer players maintained physical performance independent of Te. The specific characteristics of the sport may have promoted adequate thermoregulatory adaptations, helping maintain the players’ physical performance, particularly in matches played under high Te conditions. Elite beach soccer players maintained their physical performance independently of Te and despite experiencing dehydration (a body mass decrease of more than 2%) when the Te exceeded 35 °C.

A survey was conducted with 374 youth field hockey players (236 males, 138 females) from middle and high school teams registered with the Korea Hockey Association in 2024. Data were collected on injury status, training hours, injury sites, and prevention methods. Chi-square tests, independent t-tests, and frequency analyses were performed to assess differences in injury incidence based on gender and school level. The analysis revealed no significant gender differences in training-related injury experiences, with 17.2% of male athletes and 10.2% of female athletes reporting injuries during training. Similarly, no significant difference was found between middle and high school athletes, although high school athletes had a significantly lower injury incidence than middle school athletes (1.54 vs. 2.28 per 1000 h, p < 0.05). The most common injury sites were the ankle and knee, with muscle injuries being the most frequent among males and ligament injuries among females. Additionally, male and high school athletes more frequently reported engaging in warm-up and cool-down exercises. There was no significant difference in injury rates between genders during training, but high school athletes tended to experience fewer injuries than middle school athletes. Ankle injuries were the most common, with muscle and ligament damage being the primary types of injuries. While warm-up exercises were commonly practiced, further research is needed to determine their actual effectiveness in injury prevention.

Mental health challenges significantly impact NCAA Division III student athletes, often leading them to discontinue their sport. Unlike Division I athletes, they have limited institutional support, making it harder to balance academic and athletic demands. This qualitative study examines the mental health barriers influencing 21 former Division III athletes’ decisions to withdraw. Key themes include stress, burnout, identity loss, inadequate institutional support and external pressures like academics and finances. The findings highlight the need for better mental health resources, reduced stigma, and stronger institutional support. Addressing these challenges can improve athlete well-being and retention in Division III programs.

The present study investigated the acute effects of different stretching modalities applied within a warm-up on flexibility and vertical jump height. Thirty-seven young adults participated in four randomized experimental sessions, each corresponding to a different condition: static stretch (SS), dynamic stretch (DS), contract–relax with antagonist contraction (CRAC) or a control condition with no stretch (CTRL). Conditions were five min in total duration, including 2 × 15 s stretches for each muscle group (knee flexor, knee extensor, and plantar flexor muscles). Ten min and five min of cycling preceded and followed these procedures, respectively. Hamstring flexibility and a series of countermovement jump (CMJ) measurements were interspersed within this procedure. Except for CTRL, hamstring flexibility significantly increased (p < 0.01) after all experimental procedures (7.5 ± 6.6%, 4.1 ± 4.9%, and 2.7 ± 6.0% for CRA, SS, and DS, respectively). The relative increase was significantly greater for CRAC as compared CTRL (p < 0.001). Vertical jump height significantly decreased (p < 0.05) immediately after SS (−2.3 ± 3.9%), CTRL (−2.3 ± 3.5%), and CRAC (−3.2 ± 3.3%). Jump height was unchanged after DS (0.4 ± 4.5%). Whatever the condition, no additional jump height alteration was obtained after the re-warm-up. The main findings of the present study revealed that DS is more appropriate for maintaining vertical jump height. However, stretching has no major effect when performed within a warm-up. In contrast, if the main objective is to increase flexibility, CRAC is recommended.

Background: the purpose of this study was to explore the effect of 10 weeks of yoga intervention on the mental health outcomes (stress, anxiety, and depression), quality of life, emotional regulation, and quality of sleep of medical students. Method: In the current experimental study, 220 medical students, with a mean age of 21.36 ± 2.20 years, participated in a 10-week yoga intervention at the University of Pécs. Data were collected before and after the intervention using the validated questionnaires DASS-21, WHOQOL-BREF, PSQI, and DERS. The distribution of data was checked using the Kolmogorov–Smirnov test. A paired sample T-test was used to compare the mean of the continuous variable. Stepwise linear regression was used to assess the association between mental health outcomes and quality-of-life variables. Results: The present study shows a significant reduction in (p < 0.001), depression (p < 0.001), and anxiety (p < 0.001) for participants, and overall quality of life (p < 0.001), quality of sleep (p < 0.001), and emotional regulation (p < 0.001) significantly improved after the intervention. The stepwise linear regression shows a strong association between higher levels of anxiety (β = 0.608, R2 = 0.366) and depression (β = 0.608, R2 = 0.392), with higher stress levels and improvement in environmental conditions being associated with a decrease in stress levels (β = −0.392, R2 = 0.087). Conclusions: the current study shows that yoga significantly improved the mental health and well-being of medical students, improving quality of life, quality of sleep, and emotional regulation. Registered Clinical Trial: NCT06661603.

Throwing arm injuries in baseball are related to throwing arm weakness. This case study investigated potential arm strength improvements owed to wearing a specialized intra-abdominal pressure (IAP) to prime arm strength prior to simulated competition. The randomized study design involving 13 collegiate pitchers who threw 3 bullpens of 40 pitches with visual encouragement through an LED-integrated radar gun unit wearing their typical belt, an IAP belt at regular length, and the IAP belt with 2 in cinch. A portable dynamometer evaluated throwing arm strength prior to bullpen sessions wearing each belt type to denote strength responses. Participant-specific data presented in this exploratory study indicated potential benefits for increasing throwing arm strength. Overall, higher throwing arm strength scores were seen for the majority athletes when wearing the IAP belt. As a result, this exploratory case study should inspire future research evaluating IAP influences on throwing arm strength, as elevated proximal stabilization of the core creates a new avenue for improved throwing arm function among baseball pitchers.

Cortisol is an important marker of hypothalamic-pituitary-adrenal function and follows robust circadian and diurnal rhythms. However, biomarker sampling protocols can be labor-intensive and cost-prohibitive. Objectives: Explore analytical approaches that can handle differing biological sampling frequencies to maximize these data in more detailed and time-dependent analyses. Methods: Healthy adult males [N = 8; 26.1 (±3.1) years; 176.4 (±8.6) cm; 73.1 (±12.0) kg)] completed two 24 h admissions: one at rest and one including a high-intensity exercise session on the cycle ergometer. Serum and salivary cortisol were sampled every 60 and 120 min, respectively. Six alternative sampling profiles were defined by downsampling from the observed data and creating two intermittent sampling profiles. A polynomial (1–6 degrees) validation process was performed, and interpolation was conducted to match the observed data. Model fit and performance were assessed using the coefficient of determination (R2) and the root mean square error (RMSE), as well as an examination of the equivalence, via two one-sided t-tests (TOST), of 24 h cortisol output between the observed and interpolated data. Results: Mean serum cortisol output was higher than salivary cortisol (p < 0.001), and no effect was observed for condition (p = 0.61). Second- and third-degree polynomial regressions were determined to be the optimal models for fitting salivary. TOST tests determined that serum data and estimated 24 h output from these models (with interpolation) provided statistically similar estimates to the observed data (p < 0.05). Conclusions: Second- and third-degree polynomial fits of salivary and serum cortisol provide a reasonable means for interpolation without introducing bias into estimates of 24 h output. This allows researchers to sample biomarkers at biologically relevant frequencies and subsequently match necessary sampling frequencies during the data processing stage of various machine learning workflows.

To assess the impact of metabolic stress on blood lactate, muscle damage, inflammatory and hormonal responses following a high-load (70% maximum) strength training session, we compared two methods with a similar number of repetitions but that differed by their metabolic demand: the 3/7 method consisting in two series of five sets of an increasing number of repetitions (3 to 7) with a short inter-set interval (15 s) and the 8 × 6 method that comprises eight sets of six repetitions with a longer inter-set interval (2.5 min). Blood concentrations in lactate, creatine kinase (CK), myoglobin (MB), interleukine-6 (IL-6), leukocytes, growth hormone (GH), insulin-like growth factor-1 (IGF-1) and cortisol were determined before and after each session. Lactate concentration increased more (11.9 vs. 3.1 mmol/L; p < 0.001) for the 3/7 method whereas CK and MB concentrations were augmented similarly (p > 0.05) for both methods. Inflammatory markers (leukocytes and IL-6) increased (p < 0.01) more after the 3/7 method. GH and cortisol concentrations also increased more (p < 0.001) after the 3/7 method with no difference in IGF-1 concentrations between methods. Positive associations were found between the change in lactate and changes in IL-6 (r2 = 0.47; p < 0.01), GH (r2 = 0.58; p < 0.001) and cortisol (r2 = 0.61; p < 0.001) concentrations. In conclusion, the greater lactate accumulation induced by short inter-set intervals during a high-load training session is associated with enhanced inflammatory and hormonal responses, suggesting that metabolic stress might contribute to the greater adaptative response previously observed with this method.
