Phase angle (PA) is a strong predictor of sarcopenia, fragility, and risk of mortality in obese people, while an optimal muscular function and handgrip strength (HS) are required to perform different daily activities. Although there is a general agreement that resistance training improves health status in obese people, the optimal weekly training frequency forPA and physical performance parameters is not clear.This study aimed to compare the effects of different weekly resistance training frequencies performed over a 24week exercise program on PA and HSin obese people. Forty-two women (56.2 ± 9.1 years, body mass index (BMI) 37.1 ± 4.9 kg/m 2 ) were randomly allocatedto one of two groups: a group with a highweekly training frequency of three times a week (HIGH, n= 21) and a group that performed only one weekly session (LOW, n= 21). The groups trained with an identical exercise intensity and volume per session for 6 months. Before and after the intervention period, the participants were assessed for anthropometric measures, bioimpedance analysis, and HS. There was a significant group × time interaction ( p p <0.05), even after adjusting for weight loss and menopausal status. Physical exercise performed three times a week promotes better adaptations in PA and HSwhen compared with the same program performed once a week in obese women
