Home Based or Traditional Class HIIT in Overweight Women.

Summary

The present protocol aims to evaluate the effect of two different 16-week High-intensity interval training (HIIT) programs on daily physical activity, body composition, cardiorespiratory fitness, eating behaviour, enjoyment and quality of life in overweight women. Methods: Ninety overweight women (25 - 50 years old) with a body mass index ≥ 25 kg/m2 will be randomly assigned to three groups of 30 participants: a remote home-based HIIT intervention group; a traditional HIIT intervention group; and a non-exercise control group. Both intervention groups will undergo a 16-week progressive HIIT program following the Tabata method. Participants will be assessed at baseline, 4th, 8th, and after 16-week for physical activity, body composition, cardiorespiratory fitness, eating behaviour, enjoyment and quality of life. The study will have a 16-week follow-up post intervention. Results: The participant's enrolment will begin in December 2021, and investigators will anticipate the study completion by the mid of 2022. Conclusions: The HIIT programs might have beneficial effects on daily physical activity, body composition, cardiorespiratory fitness and overall quality of life in overweight women. Moreover, it might be a more enjoyable form of exercise, once it is performed faster than other exercise forms. As a beneficial side effect, these healthy behaviours might have a favourable impact on women's eating behaviours. This study results are expected to add health and well-being professionals' evidence-based knowledge to create strategies and design home-based exercise interventions.

Interventions

OTHER

Home based HIIT

Intervention will consist in a 16-week exercise program with HIIT with a frequency of 3 days/week. The Home-HIIT group participants will attend HIIT workout sessions supervised by a specialised instructor via a videoconference application. Every HIIT workout session will have a 10 minutes' warm-up, followed by an 8/12/16/20 minutes of HIIT (stages of physical adaptation every 4 weeks) training and 5 minutes' cool-down. Tabata method will be used with eight sets of 20 seconds of exercise bouts separated by 10 seconds rest, in 2 to 5 blocks. The intervention will have four stages of physical adaptation. This group will have a follow-up period of 16 weeks.

OTHER

Traditional HIIT

Intervention will consist in a 16-week exercise program with HIIT with a frequency of 3 days/week. The Traditional HIIT group participants will attend a group HIIT workout sessions supervised by a specialised instructor in a sport facility. Every HIIT workout session will have a 10 minutes' warm-up, followed by an 8/12/16/20 minutes of HIIT (stages of physical adaptation every 4 weeks) training and 5 minutes' cool-down. Tabata method will be used with eight sets of 20 seconds of exercise bouts separated by 10 seconds rest, in 2 to 5 blocks. The intervention will have four stages of physical adaptation. This group will have a follow-up period of 16 weeks.
