Summary: This study investigated the extent of relative age effect (RAE) among Norwegian track and field athletes and found a strong RAE in the younger age groups. RAE decreases with age but remains present at the senior level. The study also revealed that RAE is stronger in explosive events and in boys, while endurance events show a stronger RAE in boys but not in girls. These findings have practical implications for the developmental opportunities of athletes, emphasizing the importance of patience and dedication from coaches, regardless of relative age.

Summary: The study found that boundaries with the most abrupt change in B and V also show little evidence of dissipation and ULF wave activity, while degraded boundaries with ULF activity are inferred to be relatively older. The distribution of relative ages suggests that the switchback boundary formation process is dynamic and evolving, even occurring near the PSP observation point inside of 40 RS.

Summary: The study found that high endurance elite athletes have lower levels of circulating C2, C3b/iC3b, and adipsin, which are associated with lower inflammatory, oxidative stress, and cellular aging markers. These complements were positively correlated with most other detected complements, pro-inflammatory cytokines, and antioxidant enzymes, but negatively correlated with telomere length in younger elite athletes. High endurance elite athletes also showed lower concentrations of 10 other complements in younger athletes compared to older counterparts.

Summary: The aim of this study was to assess the impact of the Relative Age Effect (RAE) on elite young male basketball players. It analyzed the difference between birth quarters (BQ) in terms of minutes played and efficiency ratings as performance parameters, as well as the relationship between team efficiency, team success, and RAE using a new approach. The research involved 678 players from 53 teams in six tournaments from 2014 to 2019. The findings showed a higher number of players born in the first BQ and a relationship between team RAE score, tournament ranking, and team efficiency score. There were no significant differences in performance measures between BQs.

Summary: This study investigated the relative age effect among French athletes in different track-and-field events and proposed a corrective adjustment method to highlight the true potential of athletes considering their relative age. The results showed that relative age effect exists in all types of events and is larger at higher levels of competition. The validated rebalancing method allows for compensation of the biases induced by the relative age effect. The study is rated 8 out of 10 in terms of its importance.

Summary: The study found that coach-led multisport practice in childhood/adolescence is a key factor in adult practice efficiency and performance improvement. The association between practice efficiency and performance improvement exhibits a non-linear saturation pattern, and combining track-and-field practice with other sports practice yields the best results.

Summary: This study compares two different methods based on cardiopulmonary exercise testing (CPET) to assess maximal aerobic speed (MAS) and investigates the effectiveness of two common field tests in estimating MAS in soccer. The results show that these methods tend to overestimate MAS and a uniform definition of MAS is needed. The UMTT and 1500-m-time trial may not be suitable for estimating MAS on an individual basis, but regression equations may work well on a team level.

Summary: The purpose of this study was to verify the existence of birthplace and relative age effect (RAE) among Brazilian Olympic athletes, as well as the association between birthplace effect and RAE. The data included information about Brazilian Summer Olympic athletes from 1920 to 2021. The results showed that most of the athletes were from the Southeast region, but no RAE was established regarding their birthplace. These findings can guide sports public policies in Brazilian regions, especially in the Midwest, North, and Northeast regions, which are underrepresented in Brazilian high-performance sports.

Summary: Research on occupational disorders among sports instructors, specifically those who practice continuously while teaching, is limited. This study evaluated the occupational disorders, cardiorespiratory fitness, and daily workload of fitness and swimming instructors. Fitness instructors showed a higher prevalence of musculoskeletal injuries, while swimming instructors experienced more upper respiratory tract infections. Cardiorespiratory fitness levels were similar for both groups, although female swimming instructors had higher heart rates during work compared to female fitness instructors.

Summary: This systematic review examines intervention strategies to improve agility performance in volleyball and synthesizes the tests used to evaluate agility in this sport. The results suggest that plyometric-based training shows the greatest improvement in agility. However, due to the moderate methodological quality, there is a need for more specific and controlled studies to investigate the effects of diversified training interventions on the development of agility in volleyball players.

Summary: The study aimed to assess central and peripheral mechanisms of fatigability after arm-cranking or cycling exercises. The results showed that dynamic maximal incremental exercises led to similar degrees of force loss in elbow flexors and knee extensors. However, at 20 minutes after exercise, the recovery of maximal voluntary isometric contraction (MVIC) was impaired in elbow flexors, and the ratio of low-to-high frequency doublets was lower, indicating that the recovery of neuromuscular function after dynamic maximal exercises is specific to and dependent on changes within the muscles investigated.

Summary: The study found that downhill running reduces the muscle's ability to generate maximum force and rapidly develop force. There were no changes in the early phase of force development and the absolute muscle EMG rise rate, indicating no alterations in neural mechanisms. The reduction in RFD100-200 suggests that impairments in rapid force generation are likely due to changes in muscle-tendon stiffness or muscle contractile apparatus.

Summary: This study compared the psychophysiological responses of repeated cycling sprints to exhaustion with a short exercise-to-rest ratio (1:6) between different effort durations and inspired oxygen fractions. The results showed that the number of sprints and peak power output decreased, while blood lactate increased during the 5:30 exercise compared to longer durations. However, oxygen fractions and exercise-related sensation did not affect blood lactate levels. Muscle deoxyhemoglobin increased and total hemoglobin decreased with increasing sprint duration. The study concluded that oxygen levels did not modify the psychophysiological responses during repeated-sprint exercise with a short exercise-to-rest ratio, and sprint duration was the primary factor affecting performance and muscle oxygenation.

Summary: The purpose of this study was to investigate the effect of acute mental fatigue on tennis serve performance and accuracy. Ten male tennis players participated in a randomized, counterbalance and crossover study. The results showed that acute mental fatigue led to a reduction in serve accuracy, but had no impact on serve speed. Therefore, tennis players should avoid cognitive efforts before training and matches to prevent negative effects on their technical performance.
