简要总结
This study aims to investigate the effects of a 4-week altitude training program on adolescent male rowers. The research will examine changes in athletic performance, athletic body composition, athletic cardiac function, athletic pulmonary function, and selected blood markers. Participants will be stratified by biological maturation based on peak height velocity to explore whether maturity influences athletic training adaptations. Measurements will include non-invasive assessments of athletic performance, athletic body composition, athletic heart and lung function, as well as venous blood sampling for hematological markers. The study intends to provide evidence for optimizing high-altitude training strategies in youth rowing.

研究组 & 干预措施
Post-PHV group
Participants in the Post-PHV group are adolescent male rowers stratified by biological maturation (PHV offset). They will undergo the same 4-week high-altitude training program, including aerobic, anaerobic, and sport-specific rowing exercises. Pre- and post-training measurements of athletic performance, athletic body composition, athletic cardiac and pulmonary function, and hematological markers will be collected.
干预措施: 4-Week Altitude Training (Behavioral)
Mid-PHV group
Participants in the Post-PHV group are adolescent male rowers stratified by biological maturation (PHV offset). They will undergo the same 4-week high-altitude training program, including aerobic, anaerobic, and sport-specific rowing exercises. Pre- and post-training measurements of athletic performance, athletic body composition, athletic cardiac and pulmonary function, and hematological markers will be collected.
