Summary: This study found that postgame PCM cooling can accelerate the recovery of muscle function in baseball pitchers, enhancing shoulder and forearm strength. However, there were no significant differences in muscle soreness and CK activity between the two groups.

Summary: Athletes often push themselves to their limits to enhance performance, but overtraining can be detrimental. This study showed that in a healthy state, the 55/80 training regimen reliably increased salivary cortisol and testosterone levels, providing insights into hormonal responses to intense exercise.

Summary: This study analyzed the extent of fatigue responses and recovery time after female soccer matches. The findings showed the presence of acute fatigue after matches, with different recovery timelines for performance, physiological, and perceptual parameters. These results are important for planning training and match schedules.

Summary: The study aimed to assess the effects of curcumin supplementation on exercise-induced muscle damage, muscle soreness, inflammation, muscle strength, and joint flexibility. The meta-analysis showed that curcumin supplementation significantly reduced creatine kinase activity, muscle soreness, and TNF-alpha concentration, and improved muscle strength and range of motion. However, no significant changes were found in IL-6 and IL-8 levels. Further high-quality studies are needed to evaluate the long-term effects and safety of curcumin supplementation.

Summary: Increased training loads in human and equine athletes can enhance physical performance, but careful training periodization and recovery time are crucial to prevent overtraining syndrome. Changes in testosterone and cortisol levels, as well as the testosterone to cortisol ratio, may serve as indicators of athlete's stress and adaptation. This study aimed to investigate the differences in hormone levels and acute phase response indicator in endurance and racehorses. The findings revealed that the T/C ratio could be a reliable indicator of fitness status, particularly in experienced racehorses.

Summary: BCAA supplementation reduces indirect markers of muscle damage and muscle soreness following strenuous exercise, but does not significantly impact muscle performance recovery. Further research is needed to determine the practicality of BCAA for ameliorating muscle damage symptoms in diverse populations.

Summary: The study identified that curcumin supplementation has a significant effect in reducing creatine kinase levels and muscle soreness index among adults after exercise-induced muscle damage. Subgroup analysis further demonstrated the efficacy of curcumin based on factors such as follow-ups after exercise, dose of curcumin, duration of studies, exercise type, train status, and study design. This suggests that curcumin may be a priority agent for exercise-induced muscle damage recovery interventions.

Summary: The aim of this study was to evaluate the hormonal response of wheelchair rugby participants under a half-year training cycle. The study found a significant change in cortisol concentration in the blood of Wheelchair Rugby players between two research periods, and a correlation between changes in free testosterone/cortisol concentration and creatinine concentration. Due to the significant loss of spinal cord injury capacity and the possibility of life-threatening trends, the anabolic/catabolic status of players should be monitored using blood biochemical indices.

Summary: This study investigated the effects of acute repeated hypoxia-hyperoxia preconditioning on resistance exercise-induced muscle damage in male athletes. The results showed that alternating hypoxic/hyperoxic air preconditioning could attenuate muscle soreness and damage after exercise, but had no effect on muscle strength recovery.

Summary: This study investigated the impact of a 6-month training program on the training-related stress indicators of youth soccer players. The results showed that training loads had a significant effect on biochemical markers, and reducing the training loads during the competitive period resulted in a decrease in these indicators.

Summary: This study investigated the effects of the active pill phase vs. withdrawal phase of a monophasic oral contraceptive cycle on exercise-induced muscle damage in resistance-trained women. The results showed that an eccentric squat-based exercise session can cause muscle damage without inflammation response, with higher CK concentrations observed in the withdrawal phase, suggesting vulnerability to muscle damage during this phase.

Summary: The study suggests that while age has a smaller impact on performance and recovery in team sports, age-related differences in recovery should still be taken seriously to optimize training stress monitoring, prevent injuries, and improve performances. Younger players outperformed older players in high-intensity sprints, but showed different recovery abilities, with older players possibly needing longer recovery time.

Summary: Blood-based biomarkers can provide objective and individualized measurements for training load, recovery, and health status. However, there are challenges in using and interpreting these biomarkers due to confounding variables, inter-individual differences, and statistical considerations. The lack of universally applicable reference levels further complicates the interpretation and load management using biomarkers.
