Resumen
- The purpose of this study was to analyze the effects of resistance training (RT) exercise order on muscle strength, hypertrophy, and anabolic hormones in older women. Forty-four older women were randomly assigned to 1 of 3 groups: a nonexercise control group (CON, n = 15) and two RT groups that performed a 12-week RT program in a multijoint to single-joint order (MJ-SJ, n = 14), or in a single-joint to multijoint order (SJ-MJ, n = 15). The RT protocol (3x/week) encompassed 8 exercises, with 3 sets of 10-15 repetitions performed per exercise. One repetition maximum tests were used to evaluate muscle strength; dual-energy X-ray absorptiometry was used to estimate lean soft tissue. Both training groups showed significant and similar increases in muscle strength (MJ-SJ = 16.4%; SJ-MJ = 12.7%) and mass (MJ-SJ = 7.5%; SJ-MJ = 6.1%), whereas there were no significant changes in testosterone and insulin-like growth factor 1. The results suggest that both approaches are similarly effective in eliciting morphofunctional improvements in older women.
