BFR+LIFT group:Low-intensity functional training at 30% estimated 1RM with bilateral proximal-thigh blood flow restriction. Cuff pressure was set at 40%-60% of estimated arterial occlusion pressure. T
HIFT group:High-intensity functional training at 70% estimated 1RM without blood flow restriction. Training was performed 3 times per week for 8 weeks, approximately 80 min per session.
