Acute Energy Expenditure to Concurrent Aerobic and Hydraulic Resistance Exercise in Obese Women |
|
Abstract |
I t has been reported that combining both hydraulic resistance exercise and aerobic exercise (PACE) improves cardiorespiratory fitness and muscular strength in non-obese individuals. This study examined the effect of PACE training in obese women on energy expenditure during moderate self-selected intensity exercise. We tested the hypothesis that PACE training would elicit greater energy expenditure than stationary cycle exercise. Ten obese women completed a maximal exercise test. On separate days, all participants performed a submaximal PACE and a stationary cycle exercise trial. Submaximal energy expenditure (6.2±0.4 vs. 5.5±0.4 kcal/min), oxygen uptake (20.3±0.75 vs. 18.1+0.57 ml/kg/min), heart rate (142±5 vs. 136±6 bpm), percentage of oxygen uptake reserve (64.5+5 vs. 55.4±3%), and percentage of maximal heart rate 79±4 vs. 76±4%) were significantly higher during PACE compared to cycling exercise. Results suggest that self-selected PACE training optimizes energy expenditure during submaximal intensity exercise in obese individuals. |
