Intervenção / Tratamento |
|---|---|
|
Experimental: 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.
|
Participants undergo a 4-week altitude training program, including aerobic, anaerobic, and sport-specific rowing exercises.
Both Post-PHV and Mid-PHV groups receive the same training protocol.
Pre- and post-training assessments include athletic performance, athletic body composition, athletic cardiac and pulmonary function, and hematological markers.
Participants are stratified by biological maturation (PHV offset) to explore whether maturity influences training adaptations.
