简要总结
The study was conducted using a randomized controlled trial design. Participants who met the inclusion criteria were randomly assigned to either the "Classic Squat Group" or the "Heel-Elevated Squat Group." Both groups completed an 8-week strength training program consisting of three sessions per week, following the resistance exercise principles recommended by the American College of Sports Medicine. The main component of the program was the assigned squat variation.
Baseline and post-intervention assessments at 8 weeks were performed according to standardized protocols. Exercise sessions were supervised by an experienced physiotherapist to ensure proper technique and minimize injury risk. Training intensity was progressively increased based on participants' adaptation and one-repetition maximum (1-RM) strength levels.

结局指标
主要结局
Muscle Strength (Isomed 2000 Isokinetic Dynamometer)
时间窗: Baseline and 8 weeks post-intervention
Quadriceps muscle strength was assessed using a Isomed 2000 isokinetic dynamometer, which is considered a gold-standard method for evaluating muscle performance. Isokinetic testing measures maximal torque produced by the muscle throughout the range of motion at a constant angular velocity, providing reliable data on muscle function. Knee extension strength were evaluated.
次要结局
- Assessment of Muscle Thickness(Baseline and 8 weeks post-intervention)
