Interventions
High-load group:Complete plantarflexion centrifugation in the extended knee position over the full range of joint motion by performing one set of 30 centrifugal resistances at 30% 1RM with 30 seconds
BFRT-Thigh group:Pressure was applied through a blood flow restriction band, using a restriction level of 50% AOP, placed under the groin of the proximal thigh.
