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)
