Summary

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.

Detailed description

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.

Conditions

• Circuit-based High Intensity Interval Training
• Body Composition
• Resting Metabolic Rate
• Habitual Physical Activity
• Performance

Interventions

Type	Name	Description
BEHAVIORAL	DoIT workout	A hybrid small-group (5-10 women/session) training modality, that combines interval training, resistance exercise and functional training and performed according to a periodized model of exercise prescription as an alternative approach for weight management. FFIT was performed 3 times/week with 48 hours recovery between sessions for 40 weeks.
BEHAVIORAL	DoIT workout - Detraining	A hybrid small-group (5-10 women/session) training modality, that combines interval training, resistance exercise and functional training, performed according to a periodized model of exercise prescription for a 20-week period (3 times/week). Immediately after a 20-week detraining period (no training was performed) was followed.
BEHAVIORAL	Control - No training	No training was performed during a 40-week period. Participation only in measurements.
