Summary: This study analyzed maturity status, relative age, and constituent age effects in young Under 14 (U14) and 16 (U16) Iberian male kayakers. It found that there were no significant differences in the distribution of kayakers by birth quarter in both age categories, but a higher proportion of top performers were born in the first half of the year. This suggests that talent detection and selection systems based solely on performance may introduce bias, and a grouping system similar to bio-banding could be a way to address this.

Summary: This study examines the associations between cumulative training load, travel demands, and recovery days with athlete-reported outcome measures and countermovement jump performance in professional basketball. The results show that training load is negatively associated with fatigue, soreness, and sleep, while increased recovery days are associated with improved soreness scores. Furthermore, increased travel hours and days away from home are associated with increased sleep quality and duration. These findings emphasize the importance of considering multiple measures to understand fatigue and recovery cycles in athletes.
