Official title
Effects of a 4-Week Altitude Training on Sport-Specific Performance, Body Composition, and Cardiac and Pulmonary Function in Adolescent Male Rowers: The Potential Role of Maturation
Overview
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.
Interventions
- Behavioral 4-Week Altitude Training
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.
Primary outcome measures
- Peak Power During Wingate Test [Time frame: Pre-training and immediately post 4-week altitude training]
- Maximal Oxygen Uptake [Time frame: Pre-training and immediately post 4-week altitude training]
- Mean Power Output During 1500 m Rowing Test [Time frame: Pre-training and immediately post 4-week altitude training]
- Body Weight [Time frame: Pre-training and immediately post 4-week altitude training]
- Body Fat Percentage [Time frame: Pre-training and immediately post 4-week altitude training]
- Forced Vital Capacity (FVC) [Time frame: Pre-training and immediately post 4-week altitude training]
- Maximal Voluntary Ventilation [Time frame: Pre-training and immediately post 4-week altitude training]
- Left Ventricular Volume [Time frame: Pre-training and immediately post 4-week altitude training]
- Ejection Fraction [Time frame: Pre-training and immediately post 4-week altitude training]
- Myocardial Thickness [Time frame: Pre-training and immediately post 4-week altitude training]
Secondary outcome measures (5)
- Muscle Mass [Time frame: Pre-training and immediately post 4-week altitude training]
- Red Blood Cell Count [Time frame: Pre-training and immediately post 4-week altitude training]
- Hemoglobin [Time frame: Pre-training and immediately post 4-week altitude training]
- Hematocrit [Time frame: Pre-training and immediately post 4-week altitude training]
- Erythropoietin [Time frame: Pre-training and immediately post 4-week altitude training]
