简要总结
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).
详细描述
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.

研究组 & 干预措施
NASM OPT Group
Behavioral: NASM OPT Program 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.
干预措施: NASM OPT Group (Behavioral)
General Exercise Group
Behavioral: General Exercise Three 60-minute weekly sessions of brisk walking and light aerobics without targeted resistance training.
