An interventional study of NASM OPT Group and General Exercise Group in Low Back Pain, Muscle Weakness and Body Image Disturbance, sponsored by University of Sistan and Baluchestan. Enrolling by invitation at 1 site in Iran. Open to female participants aged 20 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-05-06.

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).
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.
