The purpose of this study was to compare the excess post-exercise oxygen consumption (EPOC) between different types of exercises in women with normal weight obesity (NWO).
Nine university students with NWO having body mass index <25 kg/m2 and body fat percentage >30% participated in the study. First, continuous exercise (CEx) on an ergometer for 30 minutes at 60% of maximal oxygen consumption (VO2max) and interval exercise (IEx) at 80% VO2max for 2 minutes were performed. This was followed by exercise performed at 40% VO2max for 1 minute and at 80% VO2max for 3 minutes, performed 6 times repeatedly for a total of 26 minutes. The accumulation of short duration exercise (AEx) was performed for 3-bouts of 10 minutes each at 60% VO2max.
The major findings were as follows: energy consumption during the exercises showed no significant difference between CEx, IEx, and AEx; EPOC was higher in IEx and AEx as compared to CEx for all dependent variables (e.g. total oxygen consumption, total calorie, summation of heart rate, and EPOC duration); and the lipid profile showed no significant difference.
Our study confirmed that when homogenizing the energy expenditure for various exercises in NWO individuals, EPOC was higher in IEx and AEx than in CEx. Therefore, IEx and AEx can be considered as effective exercise methods for increasing energy expenditure in NWO females.
本研究旨在比较体重正常但肥胖（NWO）的女性在不同类型运动后的过量氧耗（EPOC）情况。
九名体重正常但肥胖的大学生参与了该研究，他们的体重指数<25kg/m²且体脂百分比>30%。首先，在测力计上以最大耗氧量（VO2max）的60%进行30分钟的持续运动（CEx），并以VO2max的80%进行2分钟的间歇运动（IEx）。随后，以VO2max的40%进行1分钟运动，再以VO2max的80%进行3分钟运动，重复6次，共计26分钟。还进行了短时间累积运动（AEx），以VO2max的60%每次进行10分钟，共3组。
主要研究结果如下：运动期间的能量消耗在CEx、IEx和AEx之间无显著差异；对于所有因变量（如总耗氧量、总卡路里、心率总和以及EPOC持续时间），IEx和AEx的EPOC均高于CEx；血脂谱无显著差异。
我们的研究证实，当使NWO个体各种运动的能量消耗相同时，IEx和AEx的EPOC高于CEx。因此，IEx和AEx可被视为增加NWO女性能量消耗的有效运动方法。
