NASM OPT for Pectoral Enhancement and Breast Firmness in Non-Athletic Women: An RCT
Sponsor: University of Sistan and Baluchestan
Summary
This RCT investigates a 12-week NASM OPT program targeting pectoral muscle strength, breast aesthetics (firmness, lift, chest 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 pectoral strength (dynamometer), aesthetic satisfaction (Likert scale), and functional performance (push-up test).
