Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Low-Intensity Normoxia
Participants will be breathing room air, and perform low-intensity lower-body resistance exercise.
low-intensity resistance training
4 sets of 30/15/15/15 repetitions of leg press exercise with a load of 20-30% of one-repetition maximum (weeks 1-3: 20%, weeks 4-6: 30%) in normoxic conditions performed twice a week for 6 weeks.
High-Intensity Normoxia
Participants will be breathing room air, and perform high-intensity lower-body resistance exercise.
high-intensity resistance training
4 sets of 10 repetitions of leg press exercise at 70-80% one-repetition maximum (weeks 1-3: 70%, weeks 4-6: 80%) in normoxic conditions performed twice a week for 6 weeks.
Low-Intensity Normoxia with Blood Flow Restriction
Participants will be breathing room air, and perform low-intensity lower-body resistance exercise combined with blood flow restriction.
low-intensity resistance training combined with blood flow restriction
4 sets of 30/15/15/15 repetitions of leg press exercise with a load of 20-30% of one-repetition maximum (weeks 1-3: 20%, weeks 4-6: 30%) in normoxic conditions with lower-limbs blood flow restriction (80% total occlusion pressure) performed twice a week for 6 weeks.
Low-Intensity Hypoxia
Participants will be breathing a 13% oxygen gas mixture, and perform low-intensity lower-body resistance exercise.
low-intensity resistance training in hypoxia condition
4 sets of 30/15/15/15 repetitions of leg press exercise with a load of 20-30% of one-repetition maximum (weeks 1-3: 20%, weeks 4-6: 30%) in hypoxia conditions (3500 meters above sea) performed twice a week for 6 weeks.
Low-Intensity Hypoxia with Blood Flow Restriction
