Emotion regulation strategies, specifically expressive suppression (ES) and cognitive reappraisal (CR), are known to influence mental health outcomes in the general population and adult elite athletes. Young elite athletes, who face unique academic and athletic pressures, remain understudied in this regard. The main aim of this study was to examine the relationship between ES and CR and mental health in young elite athletes. This longitudinal study included 93 young elite athletes (aged 15–17) attending upper secondary education in Sweden. Participants completed the Emotion Regulation Questionnaire and the General Health Questionnaire at three time points over 12 months. Linear mixed models were used to examine associations between ES, CR, and mental health. Higher use of ES was significantly associated with poorer mental health (β = 0.34, p < 0.001), while greater use of CR predicted better mental health (β = −0.33, p < 0.001) across the study period. Expressive suppression and CR are both important for the mental health of young elite athletes, with CR being protective and ES conferring risk. Given the observed associations, future research could examine whether interventions aiming to enhance CR and reduce ES are linked to better mental health in young elite athletes.

Background: Systematic reviews with meta-analyses play a critical role in synthesizing evidence on injury prevention programs in football. However, their utility depends on transparent and complete reporting, as promoted by the PRISMA 2020 guidelines. Aim: To assess the reporting quality of meta-analyses of randomized controlled trials (RCTs) on knee and ankle injury prevention programs in football players, using the PRISMA 2020 checklist. Methods: A methodological review was conducted following a preregistered protocol. Systematic searches in four databases (Scopus, Web of Science, PubMed, Cochrane) identified eligible meta-analyses including only RCTs on exercise-based prevention of knee or ankle injuries in football players. PRISMA 2020 adherence was evaluated across 52 items using a 3-point scale. Data were independently extracted and assessed by two reviewers. Results: Five meta-analyses met the inclusion criteria. Overall adherence to PRISMA 2020 was moderate (mean score = 70.38%), with substantial variability across sections. The Title (100%), Introduction (95.0%), and Discussion (90.0%) were best reported, while the Abstract (57.3%) and Other Information (47.3%) sections showed the lowest adherence. The Methods sections (74.7%) and the Results sections (74.5%) demonstrated a moderate level of adherence. Key underreported items included protocol registration, funding, data availability, and certainty of evidence. Conclusions: Despite moderate adherence, significant reporting gaps remain in meta-analyses on football injury prevention. Stricter enforcement of PRISMA guidelines is essential to improve transparency, reproducibility, and the practical impact of evidence syntheses in sports medicine.

Self-myofascial release tools like foam rollers and massage guns are being integrated into athlete warm-ups with increasing frequency, but evidence on their acute effects is limited. Sixteen healthy, trained athletes (23.2 ± 1.3 years; four female) completed three warm-up conditions in a randomised, crossover design separated by >48 h: dynamic warm-up plus foam rolling (FOAM), dynamic warm-up plus massage gun (GUN), and dynamic warm-up alone (CON). After each intervention, participants completed a countermovement jump (CMJ; height and reactive strength index [RSImod]), a 10/5 repeated jump test (RJT), a 20 m sprint, and a knee-to-wall ankle mobility test. Perceived soreness and fatigue were recorded. Linear mixed models and Cohen’s d were used to assess between-condition differences. Relative to CON, FOAM and GUN were associated with reduced CMJ height (d = −0.29 to −0.36) and RSImod (d = −0.40 to −0.52; p’s < 0.05). GUN was associated with significantly impaired sprint time (d = 0.34). There were modest improvements in ankle mobility (left side) following FOAM (d = 0.23, p < 0.05) and lower levels of muscle soreness compared to CON (p < 0.05). Despite some improvements in ankle mobility and muscle soreness with foam rolling, both foam rolling and massage gun use may acutely impair aspects of physical performance compared to a dynamic warm-up alone.

Despite the known relevance of punch impact in boxing, limited evidence exists regarding how anthropometric and muscle performance variables contribute to it. This study investigated the relationship between anthropometric characteristics, muscle power and strength performance, and punch impact power in 69 boxing practitioners (mean ± SD age: 27.0 ± 6.1 years). Anthropometric variables (body height (BH), armspan (AS), body mass (BM)) and muscle power and strength tests (countermovement jump (CMJ), one repetition maximum in bench press (1RM BP), and handgrip strength (HS)) were assessed. Punch impact power was assessed with PowerKube (PK), a specific device designed to measure punch impact power. Punch impact power was positively correlated with BH, AS, and BM. Linear regression indicated that BH and AS explained about 36% of the variance in Straight punch impact power and 30–34% in Hook punch impact power. BM showed weaker predictive capacity, explaining 10% of the variance in Straight punch impact power and 11% in Hook punch impact power. When comparing punch impact power differences across groups with varying BH, AS, and BM, it was found that groups with High BH exhibited higher punch impact power than the groups with Low and Medium BH for both Straight and Hook punches. For AS, the High AS group also demonstrated higher punch impact power, with similar trends for BM, where significant differences were observed only between the High and Low BM groups. Additionally, our findings confirm significant relationships between anthropometric characteristics, muscle power, and strength performance. These findings highlight the importance of a comprehensive assessment of anthropometric profiles, alongside muscle power and strength evaluations, to better predict punch impact power. This approach provides valuable insights for boxing training and may also inform exercise programming for the general population.

(1) Background: Recent decades have seen growing interest in neuroplasticity and the activity-dependent mechanisms that allow Brain Networks to adapt functionally. Among the various stimuli, physical exercise has emerged as a key modulator of brain plasticity. This narrative review aims to synthesize evidence on the structural and functional effects of physical exercise on the brain in healthy individuals aged 18–80 years. Exercise modalities were categorized into Cardiovascular, Strength, and Mixed Training. Each was further classified by intensity (Light-to-Moderate vs. Vigorous) and duration (Short- vs. Long-Term). A total of 25 interventions were analyzed to evaluate how these variables influence Brain Networks. Findings indicate that exercise type, intensity, and duration collectively modulate neuroplastic responses. Notably, physical training induces structural and functional changes in major Brain Networks, including the Default Mode Network, Salience Network, Central Executive Network, Visuospatial Network, Sensorimotor Network, and Language and Auditory Networks. These results underscore the potential of physical exercise as an effective non-pharmacological strategy to enhance brain health and plasticity across the adult lifespan. This narrative review aims to highlight the effects of physical exercise in changing the brain either functionally or structurally. Moreover, the most relevant exercise training modalities that may improve/change neural networks in healthy populations (18–80 years) were discussed. (2) Methods: Three different types of exercise were considered: (i) Cardiovascular, (ii) Strength, and (iii) Mixed Exercise. For each of them, two levels of intensity (Light-to-Moderate and Vigorous) and two durations (Short-Term and Long-Term Effects) were included. By analyzing 25 interventions, indications about the effects on the brain considering the three factors (type of exercises, intensities, and durations) were provided. (3) Results: The findings suggest that the type of exercises, intensities, and durations could to lead neural modification over time. Specifically, exercise intervention contributes to both structural and functional changes in brain regions located in key Brain Networks, including the Default Mode Network, Salience Network, Central Executive Network, Visuospatial Network, Sensorimotor Network, and Language and Auditory Networks. (4) Conclusions: In conclusion, the evidence presented herein underscores the beneficial effects of physical exercise on the structural and functional integrity of the brain, highlighting its importance as a non-pharmacological intervention to improve brain plasticity.

Background: Handgrip strength asymmetry is a critical yet underexplored basketball component. While the digit ratio (2D:4D) is linked to strength, its interplay with age, body composition, and biomechanics is unclear. This study aimed to quantify these independent and interactive effects on asymmetry in female basketball players. Methods: Maximum handgrip strength was measured bilaterally in three arm postures in 26 adolescent and adult players. Linear Mixed Model with a random intercept tested the effects. Results: Omnibus tests revealed no statistically significant main effects or interactions for age group, lean body mass (LBM), or 2D:4D ratio. However, a planned contrast showed that asymmetry was significantly lower in an overhead arm posture compared to an extended arm posture (p = 0.035). A simulation-based power analysis determined the study was significantly underpowered (11.5%) to detect small-to-medium interaction effects. Conclusions: While biomechanical position subtly modulates strength asymmetry, the influence of age, lean mass, and digit ratio may be negligible or require substantially larger samples to detect. Individual differences, which accounted for 57% of the variance, appear to be the dominant drivers of handgrip asymmetry in this athletic cohort, highlighting the complexity of strength imbalances and the critical need for adequately powered research in this domain.

This study examined the prevalence of intentionally unreported and potentially unrecognized concussions in community rugby players and whether nondisclosure reasons vary by sex, position, or playing history. An online survey was completed by 1037 players (41.0% female; mean age 31.6 ± 11.3 years; 10.1 ± 8.1 years playing) who reported diagnosed, unreported, and unrecognized concussions. Poisson regression models estimated prevalence ratios (PRs), and Fisher’s exact tests compared reasons for nondisclosure. The diagnosed, unreported, and unrecognized concussion rates were 66.5%, 32.4%, and 42.2%, respectively. Players with diagnosed concussions had a 7.2-fold higher prevalence of nondisclosure and a 2.3-fold higher prevalence of nonrecognition. A longer playing history was linked to greater nondisclosure (PR: 1.2), and males had a higher prevalence of nonrecognition (PR: 1.4). Position and sex were not associated with nondisclosure; position and playing history did not affect recognition. While nondisclosure reasons were mostly consistent across demographics, players with a history of concussion were more likely to report avoiding removal from games or practices (38.5% vs. 13.6%, p = 0.021). Concussions are common in community rugby, with high rates of underreporting and unawareness, influenced by experience and prior concussions. These findings underscore the need for better education and reporting systems to improve player safety.

Background: Several physical qualities have been linked to countermovement jump (CMJ) performance. However, the relative importance of each of these factors is unclear. (1) Objectives: The present systematic review sought to evaluate the characteristics associated with CMJ performance in adult team-sport athletes. (2) Methods: A comprehensive search of three databases and the grey literature yielded 18 articles that met the inclusion criteria. Pearson’s correlation coefficient was used to assess statistically significant relationships and interpreted as negligible (0.00–0.10), weak (0.10–0.39), moderate (0.40–0.69), strong (0.70–0.89), and very strong (0.90–1.00). (3) Results: Eighteen articles remained eligible, with an average quality score of 76% ± 14 on the Joanna Briggs Institute critical appraisal index. The strongest correlations reported included time-to-bottom, time-to-peak force, knee extension peak power at 180 °/s, and squat jump height. (4) Conclusions: The conclusions drawn from this study suggest that, to maximize CMJ performance, priority should be given to movement biomechanics and lower-body power whilst considering individual braking-phase strategies. These findings may inform training programs aimed not only at enhancing athletic performance but also at reducing injury risks associated with poor jumping mechanics in team sports.

Background: Aging is associated with reduced joint flexibility and balance, which increases the risk of falls, especially during stair descent where motor control is critical. Stretching has been shown to improve ankle range of motion and gait speed. This study investigated the effects of a 4-week training program combining stretching plus resistance training (RT) with elastic bands on functional capacity and ankle stability during stair descent in older women. Methods: Twenty-four active older women (mean age: 73.1 ± 0.97 years) were randomly assigned to static stretching (SS), dynamic stretching (DS) and control (CG) groups. All participants completed two weekly 60 min sessions consisting of progressive RT preceded by three different warm-ups. The SS and DS groups completed static or dynamic stretching, while the CG walked. Assessments included 30s-Chair Stand (30s-CS), Handgrip Strength (HGS), Time Up and Go (TUG), Chair Sit and Reach (CSR), Rating of Perceived Exertion (RPE), and ankle kinematics during stair descent. Results: All groups improved 30s-CS and TUG (p < 0.05). Only the SS group improved CSR in both legs and the ankle dorsiflexion angle during stair descent at final foot contact (p = 0.002). RPE increased over time across all groups (p < 0.0001); however, the SS and DS groups reported lower exertion than the CG group in first–second weeks (p = 0.0001–0.003). Conclusions: SS prior to progressive RT improved flexibility and ankle kinematics during stair descent, thus reducing the perception of effort particularly during the initial training phase. These findings indicate the effectiveness of SS as a warm-up strategy for increasing ROM and potentially reducing the risk of falls in this population.

This study aimed to examine the effects of different stretching techniques on repeated sprint performance and to assess the influence of the sequence in which static and dynamic stretching are performed. Ten male Division II soccer players (age: 22.80 ± 1.13 years; height: 180.60 ± 3.59 cm; body mass: 70.60 ± 6.04 kg) completed a repeated sprint test consisting of 6 × 30 m sprints after five different warm-up protocols in a randomized, counterbalanced design: (1) general warm-up without stretching (NS), (2) static stretching (SS), (3) dynamic stretching (DS), (4) SS followed by DS (SS-DS), and (5) DS followed by SS (DS-SS). Stretching was performed during the recovery periods between sprints: ~6 min for SS and DS, and ~12 min for combined protocols. Sessions were spaced 72 h apart. Performance metrics included mean sprint time, best sprint time, and total sprint time. ANOVA and Cohen’s d were used for statistical analysis. Repeated sprint test performance was significantly enhanced after DS compared to SS, DS-SS, and SS-DS (p = 0.042–0.002; ES = 0.31–2.26), but not significantly different from NS (p > 0.05). SS had a detrimental effect when compared to DS and NS (p < 0.05; ES = 1.86–2.26). Improvements were observed in mean sprint time and total sprint time across all six sprints (p = 0.042–0.006; ES = 0.31–2.26) and in best sprint time (p = 0.006–0.002; ES = 0.89–1.86). In conclusion, DS prior to repeated sprint test improves performance compared to SS and combined methods. NS also supports strong performance but shows a slight advantage over SS and combinations. Incorporating DS into warm-up routines is recommended to optimize sprint performance, reduce injury risk, and support athlete preparation.

Purpose: This study aims to demonstrate the value of physical education (PE) in fostering prosociality and academic motivation through active approaches derived from the sports education model (SEM), in contrast with the traditional methodology (TM). One of the new features introduced is based on an approach focused on physical fitness and health that goes beyond sports practice. Method: A 10-week intervention was conducted with a sample of 127 students (n = 127). In total, 63 students (n = 63) received an SEM-based intervention and 64 (n = 64) received traditional teaching. The effect of these methodologies on motivation, prosocial climate, and the perceived importance of PE has been verified, based on a fitness-oriented proposal. Results: The findings indicate improvements in the SEM group’s prosociality (giving, p = 0.015; verbal comfort, p = 0.019; solidarity, p = 0.039). Additionally, the TM group showed increased importance attributable to PE, though a deterioration in prosocial values was also observed. No evidence was found regarding changes in motivation. Discussion/Conclusion: The implementation of SEM has positive effects on students’ prosociality, whereas the opposite effect can be observed when employing TM. The non-inclusion of sports activities can affect the motivation variable

Background: Cardiometabolic risk in adolescents represents a growing public health concern that is closely linked to modifiable factors such as physical fitness. Traditional statistical approaches often fail to capture complex, nonlinear relationships among anthropometric and fitness-related variables. Objective: To develop and evaluate supervised machine learning algorithms, including artificial neural networks and ensemble methods, for classifying cardiometabolic risk levels among Chilean adolescents based on standardized physical fitness assessments. Methods: A cross-sectional analysis was conducted using a large representative sample of school-aged adolescents. Field-based physical fitness tests, such as cardiorespiratory fitness (in terms of estimated maximal oxygen consumption [VO2max]), muscular strength (push-ups), and explosive power (horizontal jump) testing, were used as input variables. A cardiometabolic risk index was derived using international criteria. Various supervised machine learning models were trained and compared regarding accuracy, F1 score, recall, and area under the receiver operating characteristic curve (AUC-ROC). Results: Among all the models tested, the gradient boosting classifier achieved the best overall performance, with an accuracy of 77.0%, an F1 score of 67.3%, and the highest AUC-ROC (0.601). These results indicate a strong balance between sensitivity and specificity in classifying adolescents at cardiometabolic risk. Horizontal jumps and push-ups emerged as the most influential predictive variables. Conclusions: Gradient boosting proved to be the most effective model for predicting cardiometabolic risk based on physical fitness data. This approach offers a practical, data-driven tool for early risk detection in adolescent populations and may support scalable screening efforts in educational and clinical settings.

Background: This pilot study aimed to investigate the experiences of participating in a brief walking football intervention among rural older adults and explore the functional health outcomes of participation. Methods: This multi-methods study saw 13 older adults (7 males/6 females, 63.2 ± 9.4 years) complete 1-h of walking football per week for six weeks. Pre- and post-intervention, participants underwent assessments of body composition, as well as functional assessments using the Senior Fitness Testing Battery. On completion of the walking football intervention, all participants joined in a semi-structured focus group interview to explore their experiences of participation. Results: Thematic analysis of focus group data identified three themes that captured participant’s experiences, including: (1) “Opportunity to jump back in with what we can physically do”, (2) Social connection and feeling “part of something bigger”, and (3) “It’s how our brain is engaged”. Trivial changes were observed in assessments of body composition (0.07–0.08) and flexibility (0.02–0.19). Furthermore, small-to-large magnitude changes were observed for several functional health outcomes suggestive of improved walking capacity (0.72–1.6), agility (−0.9) and upper and lower body muscular strength (0.49). Conclusions: Rural older adults reported experiencing perceived health and well-being improvements from participation in a brief walking football intervention, with functional health benefits also evident; however, further suitably powered evidence is highly warranted.

Background: This study includes an investigation of lower-limb muscle strength and physical activity among children in Japan and China, with the aim of promoting children’s health. Methods: A total of 564 children (300 boys, 264 girls) aged 9–12 years from public primary schools in Tokyo, Japan, and Jiangxi Province, China, were included. Height, body weight (BW), hip adductor and abductor strength, and toe grip strength were measured. The side-step test (SST) and timed-up-and-go test (TUGT) were performed. Exercise habits were assessed via a questionnaire. Results: Japanese students produced significantly higher values than Chinese students in SST (23.3–37.1%) and TUGT (6.6–8.0%), except among 11-year-old girls. Japanese boys aged 10–11 and girls aged 10–12 had significantly greater hip adductor strength/BW and toe grip strength/BW. Japanese students also showed significantly higher hip abductor strength/BW at all ages. Additionally, the proportion of children engaging in vigorous-intensity physical activity (VPA) was significantly higher in Japanese boys aged 10–12 and girls aged 9–11 than in their Chinese counterparts. Conclusions: Chinese students showed diminished lower-limb strength and agility compared to Japanese students. These findings highlight the importance of promoting outdoor play, particularly VPA, to improve children’s physical fitness and health, especially in China.

Basketball is a sport whose regulations require quick and complex refereeing decisions. Since the inception of sports, research on sports judgment and refereeing has been consistently present in the scientific literature. However, decision-making and the psycho-emotional factors that influence it remain somewhat unexplored in studies. The decision-making of the basketball referee has been analyzed using the DMQ II questionnaire. To achieve this, 58 referees from the Spanish Basketball Federation collaborated, comprising 45 men and 13 women, all between the ages of 18 and 38 (M = 26.5, SD = 5.5). Participants completed the 31-question DMQ II questionnaire online, yielding results with significant differences based on age and gender about stress in decision-making. A modification of the referee’s teaching methodology that includes psychological strategies is proposed both in the initiation course and throughout the refereeing career. The findings highlight the need for mental health support systems for referees, particularly addressing stress management in young and female officials. This aligns with global efforts to safeguard psychological well-being in sports professionals.

The application of natural juices in sports nutrition is attracting growing interest due to their potential antioxidant, anti-inflammatory, and ergogenic properties. Exercise, especially when prolonged or intense, increases oxidative stress and muscle damage, leading athletes to explore dietary strategies that support recovery and enhance performance. This systematic review investigates the effectiveness of five widely studied juices—beetroot, pomegranate, cherry, watermelon, and pickle juice—in the context of athletic supplementation and recovery. A thorough search of the PubMed, Scopus, and Web of Science databases was conducted to identify studies published between 2010 and 2025. Fifty peer-reviewed articles met the inclusion criteria, examining various physiological, biochemical, and performance-related outcomes linked to juice consumption. Given the methodological diversity among studies, a qualitative synthesis was employed. The juices were compared across four key outcomes—inflammation, oxidative stress, delayed onset of muscle soreness, and exercise performance—to determine their most consistent benefits. Beetroot juice, noted for its high nitrate content, consistently enhanced oxygen efficiency and submaximal endurance, although benefits in elite or sprint athletes were less evident. Both pomegranate and cherry juices were effective in reducing muscle soreness and inflammatory markers, particularly when consumed over several days surrounding exercise. Watermelon juice, primarily through its L-citrulline content, offered antioxidant and recovery support, although performance outcomes varied. Evidence for pickle juice was limited, with no notable ergogenic effects beyond anecdotal cramp relief. Overall, natural juices can support recovery and occasionally improve performance, depending on the specific juice, dosage, and athlete characteristics. Beetroot juice stands out as the most reliable in enhancing performance, while pomegranate and cherry juices are more beneficial for recovery. Future research with standardized protocols is essential to determine optimal application across diverse athletic contexts.

Limited evidence exists on how segmental external load is distributed during linear running and how it varies with speed, training intensity, and individual differences. This study examines the external load profile across six body segments in elite female futsal players during linear treadmill running, focusing on the effects of speed and training zone, as well as individual variability. Eight elite players, including six outfield players and two goalkeepers (mean age 23.9 ± 3.4 years, height 164.96 ± 4.22 cm, body mass 60.31 ± 4.56 kg), performed an incremental test and were measured using six WIMU PRO™ inertial sensors. The sensors recorded segmental PlayerLoad, speed, and training zones. Data were analyzed using Linear Mixed Models. The most important results show significant interactions between body location and speed and between body location and training zone (p < 0.001), with intraclass correlation coefficients (ICC) ranging from 0.437 to 0.515. These results indicate variability among players and specific and asymmetrical segmental load patterns. These findings offer practical insights for tailoring individualized training strategies that optimize performance and reduce segment specific overuse injuries.

Adverse cardiovascular events and increased mortality are associated with cardiac autonomic nervous system dysfunction in the early stages of the systemic sclerosis (SSc), even prior to the development of cardiac fibrosis. The objective of the study was to evaluate the impact of a three-month exercise training regimen and a subsequent comparable period of detraining on the activity of the cardiac autonomic nervous system in patients with SSc. A total of forty patients with SSc were randomized to either the control group (Group COΝ) or the exercise training group (Group ET). Cardiopulmonary exercise testing was performed at baseline, three months later, and six months later to assess peak oxygen uptake (VO2peak). They also had 24 h electrocardiogram monitoring for heart rate variability (HRV) and heart rate turbulence analysis. The following time-domain indices were evaluated in the context of HRV analysis: the standard deviation of NN intervals (SDNN), the root mean square of successive RR interval differences (rMSSD), and the percentage of successive RR intervals that differ by more than 50 ms (pNN50). Additionally, regarding the frequency-domain indicators, the low-frequency (LF) and high-frequency (HF) components, as well as the LF/HF ratio, were evaluated. Independent t-tests and Chi-square tests were used for baseline comparisons, while two-way repeated measures ANOVA with Bonferroni post hoc tests assessed changes over time and between groups. Linear and multiple regression analyses were conducted to explore relationships among variables and identify predictors of HRV indices and VO2peak. Group ET implemented a three-month mixed-type exercise training program, while Group COΝ received standard care. Group ET improved indices of vagal activity [rMSSD by 32.6% (p = 0.017), pNN50 by 57.1% (p = 0.01) and HF by 20.1% (p = 0.01)] and sympathovagal activity [SDNN by 15.5% (p = 0.002) and LF/HF by 12.03% (p = 0.004)] after three months. Exercising patients also increased their VO2peak by 20.8% (p = 0.001). A robust positive correlation was observed between ΔVO2peak and ΔSDNN (r = 0.754, p < 0.001). After three months, there was no statistically significant difference in the VO2peak or any HRV index in the group COΝ. Compared to the baseline values, there was no statistically significant difference in group ET at 6 months, whereas the control group exhibited a decline. In summary, a three-month mixed-type exercise training program can enhance the cardiorespiratory efficiency and cardiac autonomic nervous system function of patients with SSc, as well as alleviate the deterioration that arises following the detraining period.

Background: Hispanic college students face high stress, which may increase their risk for chronic stress-related health issues. Effective and accessible stress management strategies for this population remain limited. Objective: This pilot study filled a gap by studying the effects of psychological stress on diet and physical activity habits and evaluating the impact of moderate-intensity physical exercise (MIPE) and yoga interventions on chronic psychological stress and acute stress responses among Hispanic college students. Methods: A total of 18 Hispanic college students participated in a 6-week intervention consisting of either MIPE or yoga, conducted twice weekly. Anthropometric measurements and lifestyle data were collected at both pre- and post-intervention timepoints. Psychological stress was evaluated using the Perceived Stress Scale-10 (PSS-10), morning salivary cortisol concentrations, and the Trier Social Stress Test (TSST). Results: Before the intervention, both perceived stress scores and morning salivary cortisol concentrations were positively correlated with the frequency of sweetened beverage intake and negatively correlated with attitudes toward exercise. Psychological stress was not significantly reduced after MIPE or yoga interventions. The salivary cortisol response to TSST was significantly improved after the yoga intervention. Conclusions: Although this pilot exploratory study suggests that short-term yoga may have beneficial effects in managing acute stress response in Hispanic college students, the efficacy of the interventions needs to be tested and replicated in a fully powered trial.

The progression of content during the training and development of young athletes is essential, while considering the developmental stages of the students/athletes. Therefore, it is crucial to monitor training sessions to ensure that content progression is followed and to assess how it is implemented. The aim of this study was to analyze the associations between different male categories of sports development in basketball through pedagogical variables and external loads planned by the coaches. The sample consisted of 148 sessions and 896 tasks, and the SIATE tool was used to observe both the pedagogical variables and the primary external load variables. Significant differences were observed primarily in the U16 category compared to the U12 and U14 categories. In examining the pedagogical variables, three key aspects were highlighted: content type, training methods, and level of opposition. The external load variables were aligned with the pedagogical variables, suggesting a progression of content. This indicates that instruction should follow an order, in which tactical load evolves from the simplest to the most complex, in accordance with the development and training stage of the students/athletes. The analyzed male basketball team demonstrated a content progression focused on the comprehensive development of the student/athlete, encouraging decision-making, and creating a complex, unpredictable, and random environment that closely resembles the dynamics of the real game.
