简要总结
In this study the investigators utilized a novel hybrid HIIT (high intensity interval training) exercise training approach, the Hybrid Interval Training (DoIT) workout that combines interval training, resistance exercise training and functional training in order to test the hypothesis that DoIT will be able to: i) reduce body mass, ii) improve body composition and iii) alter energy balance, of previously inactive, overweight/obese women.
详细描述
In a controlled randomized, two-group, repeated measures design, 65 healthy, sedentary, premenopausal overweight or obese women were randomly assigned to one of three groups: (a) a control group (C, N=21) that participated only in measurements, (b) a training group (TR, N=14) that participated in a supervised 40-week DoIT workout exercise training program and (c) a training-detraining group (TRD, N=14). During the first 20 weeks, TR and TRD followed exactly the same training protocol. At the end of this period, TR continued training for 20 more weeks whereas TRD terminated training for 20 weeks (detraining). Anthropometric, metabolic, daily nutritional intake, habitual physical activity and performance measurements were performed in all groups at baseline, at 20 weeks and 40 weeks.
