It included a 10-week control phase with no training, followed by a 10-week intervention of twice-weekly free-weight resistance training. Participants were randomly assigned to low-intensity (50% 1-RM) or moderate-intensity (75% 1-RM) groups and further divided into pre- and post-menopausal based on hormone profiles. Statistical analysis used a linear mixed model. The central result was that while significant increases in 1-RM squat and bench press strength occurred in all groups, significant hypertrophy effects (increases in fat-free mass, muscle mass, and rectus femoris muscle thickness) were found exclusively in pre-menopausal women. These effects were not present in post-menopausal women. Limitations include a relatively small sample size and a specific intervention volume (6–8 sets/muscle/week).
