Increases in Thigh Muscle Volume and Strength by Walk Training with Leg Blood Flow Reduction in Older Participants

18 older women (BFR-Walk n=10, mean age 64 ± 1 years, BMI 22.5 ± 0.9 kg/m²; CON-Walk n=8, mean age 68 ± 1 years, BMI 23.2 ± 1.0 kg/m²)

Walk training with leg blood flow reduction (BFR) using pressure belts (160-200 mm Hg) on both legs, consisting of 20 minutes of treadmill walking at 45% of heart rate reserve, 4 days per week, for 10 weeks

Control walk training consisting of 20 minutes of treadmill walking at 45% of heart rate reserve, 4 days per week, for 10 weeks without pressure belts
