Abstract

Objective: To evaluate the effect of different daily physical activity (PA) frequencies while maintaining the same daily volume of PA on weight loss, carbohydrate and lipid metabolism, in women with overweight/obesity throughout a 24- week intervention.
Methods: 65 women [BMI = 27- 35 kg/m²; age= 18-40 y] who had a sedentary lifestyle were randomly allocated to include either a longer-bout of PA (LBP), 50 min/d moderate-intensity PA, or two shorter-bouts of PA (SBP), two 25 min/d moderate intensity PA, 6 d/week during their weight loss plan. Anthropometric and blood measurements were taken at baseline and 24 weeks.
Results: Compared with the LBP group, the SBP group had a greater decrease in weight (SBP: -8.08 ± 2.20 kg; LBP: -6.39 ± 2.28 kg; P = 0.019), BMI (SBP: -3.11 ± 0.87 kg/m²; LBP: -2.47 ± 0.86 kg/m², P=0.027) and waist circumference (SBP: -8.78 ± 2.62 cm; LBP: -5.76 ± 2.03 cm; P = 0.026). No significant differences were seen in carbohydrate and lipid metabolism characteristics after the 24 weeks.
Conclusion: PA undertaken in 2 shorter-bouts per day could be more effective for weight loss than when undertaken in a daily long-bout in adult women on a 24 wk weight loss program.
