摘要：Background This study assessed the perceived benefits and barriers to exercise participation in overweight and obese women with polycystic ovary syndrome (PCOS) and monitored changes in response to a lifestyle intervention. Methods Forty-three overweight/obese PCOS women (Age, 30.3(6.2) yrs; BMI, 36.4(5.6) kg/m²) were randomised to one of three 20-week lifestyle programs: diet only (DO, n = 13), diet and aerobic exercise (DA, n = 11) and diet and combined aerobic-resistance exercise (DC, n = 19). Exercise Benefits/Barriers Scale (EBBS), weight, aerobic fitness, depression and PCOS specific health-related quality of life were measured. Results Barriers score was related to depression ( r = 0.45, P = 0.002) and aerobic fitness ( r = −0.32, P = 0.04), while benefits score was related to aerobic fitness ( r = 0.41, P = 0.007). EBBS, benefits and barriers scores improved overtime ( P ≤ 0.001). Benefits subscales psychological outlook and social interaction increased ( P ≤ 0.001) and life enhancement and preventative health did not change ( P ≥ 0.3). Physical performance increased only in DA ( P = 0.009). There were no differences between treatments for any of the other subscales ( P ≥ 0.2). Barriers subscales exercise milieu, time expenditure and physical exertion reduced ( P ≤ 0.003) and family discouragement did not change ( P = 0.6). Conclusions This study demonstrated that lifestyle modification consisting of an energy-restricted diet with or without exercise training improved the perceived benefits from and barriers to exercise.
