Abstract
Background: Exercise training reduces adiposity and risk of cardiovascular disease. However, the combined effects of habitual free-living physical activity and aerobic training on waist circumference, weight, fıtness, and blood pressure in postmenopausal women are unknown.
Purpose: To evaluate the effects of habitual physical activity levels during aerobic training on weight, waist circumference, fıtness, and blood pressure.
Design: Secondary analysis of an RCT. Original data collected April 2001 to June 2005 and analyzed in 2012.
Setting/participants: Postmenopausal women in a supervised exercise trial.
Intervention: Women (n325) were randomized to 4, 8, or 12 kcal/kg per week of aerobic training or a control group for 6 months. All outcome measures were collected at baseline and follow-up. Changes in dependent variables within each training group were evaluated across tertiles of pedometerdetermined
habitual physical activity outside exercise training sessions.
Main outcome measures: Changes in waist circumference and weight.
Results: Reductions in waist circumference were signifıcantly greater with higher steps/day accumulated outside exercise training compared to lower levels in the 4 (high:4.8 cm vs low:1.4 cm, p0.03); 8 (high:4.2 cm vs low:0.4 cm, p0.03), and 12 kcal/kg per week groups (high:4.1 cm vs low: 0.7 cm, p0.05). For all groups, p-trend0.03. A trend was observed for greater weight reduction with higher steps/day in the 4 kcal/kg per week group (p-trend0.04) but not for the other exercise doses. No effects were observed for blood pressure or fıtness measures (all p0.05).
Conclusions: In postmenopausal women, higher habitual physical activity while participating in aerobic training was associated with greater reductions in central adiposity, and was supportive of weight loss compared to lower levels.
