Blood Flow Restriction and High-intense Resistance Training in Aging: Interactions Between Neuroplasticity and Muscle

Following a warm-up of 10 min, subjects in the experimental group will undergo BFRT for two times per week, consisting of lower extremity exercises (leg press, knee extension, knee flexion). BFRT will be at 40% of 1 repetition maximum (1RM); The volume % (V% = number of repetitions x number of sets x number of exercises x % 1 repetition max) = 57.6%. Progression during the 12 week program will be attained by a 1RM test every 4 weeks.

Following a warm-up of 10 min, subjects in the experimental group will undergo MDRT for two times per week, consisting of lower extremity exercises (leg press, knee extension, knee flexion). The exercise will be at 80% of 1RM concentric-only or 120% of 1RM eccentric-only in a 3:1 ratio. The volume % (V% = number of repetitions x number of sets x number of exercises x % 1 repetition max) = 57.6%. Progression during the 12 week program will be attained by a 1RM test every 4 weeks.
