Lower-limb strength insufficiency

Interventions

Velocity-based resistance training group :Velocity-based resistance training (VBT) group (experimental group): Training intensity was determined based on real-time speed (target velocity +/-0.03 m/s
the number of repetitions per set was not fixed, and the exercise was terminated when the movement speed decreased by 10%
using a GymAware speed sensor, 4 sets of back squats, Bulgarian split squats, and deadlifts were completed, with a 3-minute rest between sets.
Percentage-based training group :Percentage-based training (PBT) group ( control group): All training is performed at 70% 1RM load, with a fixed 5 repetitions per set, totaling 4 sets, with a 3-minu
