Summary: Repeated sprint ability (RSA) is more closely related to match performance outcomes than single-sprint performance, but the kinetic determinants in youth athletes remain poorly understood. The mechanical efficiency of force application (D-RF) was found to be the primary predictor of both single and repeated sprint performance in adolescents. Training programs targeting RSA should include technique and skill acquisition components.

Summary: The present study aimed to investigate the impact of force-power-velocity, vertical and horizontal jumps, and repeated sprint ability on the sprinting performance of adult women soccer players. The findings revealed that lower-limb power, maximal speed, and peak power significantly influenced sprinting time, while vertical jump determined stride frequency.

Summary: The study aimed to explore the influence of a sports-specific intermittent sprint protocol (ISP) on wheelchair sprint performance and the kinetics and kinematics of sprinting in elite wheelchair rugby (WR) players with and without SCI. The results showed that physiological parameters increased significantly after ISP training, but sprinting peak velocity and distance traveled did not change. Moreover, there were changes in body posture and shoulder joint movement during sprinting.

Summary: In world-class female rugby sevens players, four additional repeated-sprint sessions before competition can improve repeated-sprint ability and brachial endothelial function. However, adding severe hypoxic stress during sets of repeated sprints does not provide supplementary benefits.

Summary: This study aimed to evaluate the effects of a half-time re-warm-up strategy on female basketball players. The results showed that the re-warm-up did not have significant effects on jump performance and locomotory responses during the match, but it significantly increased the distance covered at a very light speed. Heart rate and rate of perceived exertion were also higher in the re-warm-up condition.

Summary: The objective of this study was to determine the suitability of thermography to detect fatigue in male football players. Participants were divided into low and high thermal asymmetry groups based on thermography session. The results showed that thermal asymmetry in hamstrings had a significant impact on performance, while asymmetries in thighs and calves did not.

Summary: This study evaluated the effects of repeated sprint training in hypoxia on aerobic performance, repeated sprint ability, and muscle oxygenation in Rugby Sevens. The results showed that adding hypoxic training to standard training had minimal benefits in improving aerobic performance and resistance to fatigue, possibly due to enhanced muscle deoxygenation and increased levels of HIF-1 alpha and VEGF.

Summary: The study reveals that body composition, lower-body power, and aerobic fitness are closely associated with repeated high-intensity effort (RHIE) ability in rugby players. Different associations were observed between forwards and backs, suggesting the need for further research to understand the fitness determinants of backs' RHIE ability.

Summary: This study compared the effects of a 7-min shuttle jog during halftime to a control condition (seated rest) on subsequent athletic performance and lower-leg temperature in the second half. The results showed that a halftime warm-up can attenuate the negative effects of static rest on sprinting performance during the initial period of the second half.

Summary: Research in team invasion sport decision making has been mainly influenced by three perspectives, with recent attempts to integrate them. The role of stored mental representations impacts players' responses in time pressured competitive environments. Changes in game situations affect players' perception and decision-making behavior, with increased time leading to the use of declarative knowledge and decreased time leading to rapid diagnosis and updating of game knowledge.

Summary: This systematic review examined soccer-specific exercise during 120 min of play and provided practical recommendations and future research opportunities. The findings showed that players cover less distance and exhibit reduced technical performance during extra-time compared to the preceding 90 min. Carbohydrate intake may improve dribbling performance during extra-time, while recovery measures may be further compromised following extra-time compared to 90 min.

Summary: This systematic review examined the post-match recovery response in male rugby players. The findings suggest that it takes approximately 72 hours for neuromuscular, biochemical and endocrine, and subjective/perceptual responses to return to baseline after competitive rugby match-play. The lack of research focusing on ecologically valid scenarios and youth players highlights the need for further investigation.

Summary: The study aims to quantify the peak post-pitch-entry physical responses of soccer substitutes and found that substitutes introduced during the final stage of a match covered less distance compared to those introduced in the first half or after 60 minutes, while substitutes entering when their team was winning recorded greater distances. Substitute midfielders outperformed substitute attackers in total distance, and defenders in shorter match epochs.

Summary: This study evaluated the effects of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) on acute testosterone and cortisol dynamics and emotional state in healthy adults, finding that a single sub-maximal session did not significantly affect hormonal, emotional, or physiological states. However, the emergence of stimulation-specific testosterone and emotional linkages suggests that repeated effects of HF-rTMS may manifest at the individual level. This offers a potential pathway to explain therapeutic efficacy and explore interindividual variability in health-related outcomes.

Summary: This review provides a critical assessment of the existing literature on apps relevant to sport and exercise nutrition. It discusses three main areas: dietary analysis of athletes, nutrition education for athletes, and estimating body composition. The purpose is to identify the potential benefits of apps in these areas and provide considerations for practitioners before implementing or recommending their use.

Summary: This report explores the relationship between finger digit ratio and achievement. The results suggest that finger digit ratio is not predictive of hormone response to low-level exercise stress, but is associated with pupillometry measures. The finger digit ratio of journalists is significantly different from rugby players and surgeons. Therefore, finger digit ratio is likely to predict testosterone sensitivity and ability to focus attention.

Summary: This study aimed to analyze the acute glycaemic dynamics during graded exercise testing (GXT) in adults with type 1 diabetes using insulin pump therapy and explore the influence of glycaemic indicators on the physiological responses. The study found that plasma glucose concentrations remained stable during exercise and higher haemoglobin A1c levels were associated with lower aerobic rate, oxygen economy, and mechanical output.

Summary: This study investigated physiological responses to cardiopulmonary exercise testing in adults with type 1 diabetes compared to controls. The results showed that individuals with type 1 diabetes had lower peak VO2, heart rate, and power compared to controls, and displayed altered heart rate dynamics during exercise testing. These differences were not associated with HbA(1c) levels in individuals with type 1 diabetes.
