Abstract:
Purpose：The purpose of this study was to investigate the effects of change in daily physical activity during an exercise intervention on health status and physical fitness.Methods：Participants were 22 obese middle-aged men (BMI : 29.1±2.8 kg/m2, 54.1±11.4 yr). They performed 90-min exercise sessions on a regular basis 3 days per week for 3 months. Physical activity (total energy expenditure, TEE ; activity energy expenditure, AEE ; and step counts) was measured using an accelerometer. Daily physical activity was defined as that which was performed outside of the exercise class. A 3-day food record was used to estimate energy intake. Results：Body weight decreased (-3.0±2.5 kg, P＜0.05). Vital age (VA), an index of comprehensive health status, and physical fitness age (PFA), an index of comprehensive physical fitness, significantly improved (VA : -8.7±5.5 yr, PFA : -8.5±5.1 yr, P＜0.05). Energy intake remained unchanged during the intervention (＋63.7±546.1 kcal/d). Daily physical activity increased (TEE : ＋83.0±130.1 kcal/d, AEE : ＋76.9±103.3 kcal/d, step counts : ＋1789±2819 steps/d, P＜0.05). Change in daily physical activity was correlated with change in VA (AEE : r＝-0.52, step counts : r＝-0.46, P＜0.05), while change in daily physical activity did not correlate with change in PFA. Conclusion：These results suggest that changes in daily physical activity during an exercise intervention are associated with improved health status.
