Purpose: Elite swimmers often schedule altitude training camps ahead of major events in an attempt to maximize performance. However, the relationships between altitude-induced hematological changes, markers of training adaptation, and performance changes in such context are unclear. This study assessed hematological status, markers of daily adaptation, and swimming performance in elite middle-distance and distance swimmers during a 22-day altitude training camp at 2,320 m, 2 weeks prior to World Championship qualification competition.

Purpose: To gather information on practices and perceptions of high-performance experts regarding their athletes' muscle fiber-type composition (MFTC) and its estimation.

Methods: A questionnaire on the noninvasive versus invasive estimation of MFTC was completed by 446 experts including coaches and sport-science/sports-medicine staff. Moreover, the perceived importance of MFTC for training and performance optimization was assessed.

Purpose: Most athletes experience short-term training cessation because of illness, injury, post-season vacation, or other reasons. Passive muscle stiffness is a potential risk factor for a sprint-type hamstring strain injury, but limited information is available about the effect of short-term training cessation on passive muscle stiffness. The present study aimed to identify whether and how passive muscle stiffness of the biceps femoris long head (BFlh) would vary due to 2 weeks of training cessation in sprinters.

Article Synopsis
  • The study investigates how the intensity of accumulated work affects power output and performance in male professional cyclists, emphasizing the concept of 'durability'.
  • Data was collected from 17 cyclists over a competition season, assessing their maximum mean power (MMP) and critical power (CP) under varying levels of accumulated work and intensity.
  • Results showed that high-intensity work (above CP) significantly decreased MMP and CP, while lower-intensity work (below CP) did not affect performance, indicating that simply measuring total work may not accurately reflect fatigue in athletes.

Article Synopsis
  • - Durability in elite cyclists is linked to their ability to maintain performance after high-intensity efforts, and this study aimed to compare this trait across different performance levels.
  • - The study involved 49 male cyclists, divided into categories (U23, Pro Team, World Tour), and assessed their critical power and maximum mean power after accumulating different amounts of work above critical power.
  • - Results showed that U23 cyclists experienced significant performance drops at lower levels of accumulated work compared to Pro Team and World Tour cyclists, who demonstrated greater endurance and performance sustainability after high-intensity efforts.
