Hyperandrogenism (increased testosterone) enhances muscle strength after progressive resistance training in women with polycystic ovary syndrome. Studies show progressive resistance training (3/week for 16 weeks consistently) produced an increase in maximum strength. Conversely, concentration of testosterone decreased. Thus weight training promoted increases in muscle strength in those with PCOS and improved hyperandrogenism and body composition by decreasing body fat and increasing lean body mass. Therefore, it is suggested that resistance exercise programs could promote health and fitness in women of reproductive age, especially functional capacity of strength those with PCOS.
