Brief summary
This RCT evaluates a 12-week NASM OPT program targeting gluteal muscle strength, hip aesthetics (shape, lift, circumference), and low back pain in 120 non-athletic women. The intervention group performed structured resistance training, while the control group engaged in general exercise. Outcomes included gluteal strength (dynamometer), aesthetic satisfaction (Likert scale), and functional performance (squat test).
Detailed description
Participants were randomized to NASM OPT (3 weekly sessions: stabilization, strength, and hypertrophy phases) or general exercise (brisk walking/aerobics). Measurements at baseline and 12 weeks included gluteal strength, hip circumference, low back pain (VAS), and perceived aesthetics.
Interventions
Three 60-minute weekly sessions for 12 weeks, progressing through stabilization (weeks 1-4), strength endurance (weeks 5-8), and hypertrophy (weeks 9-12) phases. Exercises included hip thrusts, squats, and glute bridges.
Three 60-minute weekly sessions of brisk walking and light aerobics without targeted resistance training.
