The Fun & Functional Interval Training Randomized Clinical Trial

2017-05-02 11:08:21 | BioPortfolio


In this study the investigators utilized a novel hybrid HIIT (high intensity interval training) exercise training approach, the Fun and Functional Interval Training (FFIT) workout that combines interval training, resistance exercise training and functional training in order to test the hypothesis that FFIT will be able to: i) reduce body mass, ii) improve body composition and iii) alter energy balance, of previously inactive, overweight/obese women.


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 FFIT 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.
