Effects of Alternating Altitude Training Versus Fixed-Altitude Training on Exercise Capacity and Physiological Adaptations in Elite Race Walkers: A Randomized Controlled Trial
2026年7月16日 更新者：Chaoran Han、Macao Polytechnic University
Effects of Alternating Altitude Training Versus Fixed-Altitude Training on Physical Performance and Physiological Adaptations in Elite Race Walkers: A Randomized Controlled Trial
This randomized controlled trial aims to compare the effects of alternating altitude training and fixed-altitude training on physical performance and physiological adaptations in elite race walkers living at altitude.
Elite race walkers from Yunnan Province will be randomly assigned to either an alternating altitude training group or a fixed-altitude training group.
The alternating altitude training group will perform selected training sessions under simulated higher-altitude conditions while completing the remaining sessions at their regular altitude training base.
The fixed-altitude training group will complete all training sessions at the regular altitude.
Physical performance, race walking performance, cardiovascular function, pulmonary function, and hematological parameters will be assessed before and after the intervention to evaluate the effectiveness of the two altitude training strategies.
