Conditions
Brief summary
This study aims to determine if performing strength training in simulated altitude can cause greater improvements in muscle strength and muscle size in older adults, compared to traditional strength training at sea level conditions. The study ultimately aims to help slow the progression of muscle weakness and muscle wasting in older adults. We hypothesise that performing strength training in simulated altitude (termed hypoxia) will enhance the muscle training responses compared to training at sea level.
Interventions
Participants complete either 8 weeks of strength training in normal environmental conditions (sea level; normoxia) or 8 weeks of strength training in simulated altitude (nornobaric hypoxia). Hypoxia was generated using a nitrogen enriching machine, that replaced a fraction of oxygen with nitrogen. The selected hypoxia was 14.4% to simulate an altitude of approximately 3,300m above sea level. A trained exercise scientist supervised each training session in a one-on-one session at the University gymnasium. Resistance exercise was performed at 70% of 1 repetition maximum (1RM), using four exercises: leg extension, pectoral fly, standing row and squat. Participants completed 2 sessions weekly for 8 weeks. Each session was approximately 60 minutes in duration.
