简要总结
The POWERbreathe™ Plus: an Inspiratory Muscle Training device (IMT) with adjustable resistance.
Intervention lasts 4 weeks, with a frequency of 6 days/week, 2 series of 30 inspirations in the morning and evening.
Resistance based on 60% of the Pressure Maximal Inspiratory (PMI). Progressive increase in resistance every week.
Four laboratory visits: 2 pre-tests and 2 post-tests. Each pre- / post- test will go under normoxic and hypoxic conditions.
Measurements include Pulmonary functions (spirometry test); blood microcirculation (vascular occlusion test); gas exchanges (e.g. VO2max), cardiac parameters, heart rate variability, maximal aerobic power (incremental and time limit test)

结局指标
主要结局
sex-differences
时间窗: One week prior and in the week immediately following the intervention
Primary objective: To assess the change of a time limit duration in ergocycle after 4 weeks of inspiratory muscle training (IMT) between males and females.
Effect in hypoxia
时间窗: One week prior and in the week immediately following the intervention
Secondary objective: To assess the change of a time limit duration in ergocycle after 4 weeks of inspiratory muscle training (IMT) between hypoxia and normoxia.
