Clinical Trial Summary

It is estimated that by 2030 one in five women and one in seven men will be obese, equivalent to more than 1 billion people around the world. It should be noted that the largest number of people with obesity live in countries with low and moderate-income. In 2019, more than 160 million years of healthy life were lost in the world, due to a high body mass index (BMI), this represents more than 20% of all years of healthy life lost due to chronic diseases. Therefore, it is essential to stop the increase in obesity and reduce it at all ages, which demands comprehensive actions at the global level. Scientific evidence suggests that people with a normal BMI, but with abdominal obesity, have a higher mortality risk compared to those with a similar or even higher BMI. In addition, visceral adiposity has been associated with worse survival and with colorectal cancer.

Several methods of physical exercise have been used to counteract the adverse effects of obesity, including high-intensity functional circuit training (HIFCT). Scientific evidence indicates that HIFCT reduces fat mass, body mass, BMI, and waist circumference and improves muscle strength, maximal oxygen uptake, and health-related quality of life in overweight, obese, inactive, and with other diseases. However, no research assessed intra-abdominal fat (IAF), which, more than subcutaneous fat, is associated with cardiovascular risk factors. In addition, these studies had important methodological limitations. Therefore, the primary purpose of this study is to identify the effect of two HIFCT protocols, prolonged load (HIFCT-P) and short load (HIFCT-S), performed in a virtual environment for ten weeks on intra-abdominal fat in people between 18-40 years-old with abdominal obesity.

Description:

A randomized controlled trial with parallel arms (HIFCT-P and HIFCT-C) based on a non-inferiority hypothesis comparing two proportions. Each participant will carry out 30 sessions, three times a week, in a virtual environment. General, concentrated, and block circuits will be used, with the same exercises, but with different load distribution and different order between them. Both HIFCT-P and HIFCT-S will carry out six initial adaptation sessions through a general circuit composed of 12 exercises. Different muscle groups will be alternated. The exercises will be performed at speeds between 35 and 55 beats per minute (bpm), to ensure intensities between 50% - 60% in sessions 1 to 3, and between 70% - 80% in sessions 4 to 6. The Modified Borg Rating of Perceived Exertion Scale (RPE) will be used to control intensities. From session seven to session 30, HIFCT-P and HIFCT-S will perform the same exercises but with a different load distribution.

Intervention

Behavioral:
• HIFCT-S
A functional circuit training of 30 sessions will be carried out as follows: Sessions 1 to 6: General circuit (two series) composed of four blocks of three exercises. Sessions 7 to 14: Concentrated circuit (two sets) composed of four blocks of three exercises of greater complexity than the exercises of the general circuit. Sessions 15 to 22: Circuit by blocks (two sets) composed of four blocks of two exercises of greater complexity than the exercises from sessions 7 to 14. Sessions 23 to 30: Circuit by blocks (two sets) composed of four blocks of two exercises of greater complexity than the exercises from sessions 15 to 22.
• HIFCT-P
A functional circuit training of 30 sessions will be carried out as follows: Sessions 1 to 6: General circuit (two series) composed of two blocks of 6 exercises. Sessions 7 to 14: Concentrated circuit (two sets) composed of two blocks of 6 exercises of greater complexity than the exercises of the general circuit. Sessions 15 to 22: Circuit by blocks (single set) composed of five blocks of two exercises of greater complexity than the exercises from sessions 7 to 14. Sessions 23 to 30: Circuit by blocks (single set) composed of five blocks of two exercises of greater complexity than the exercises from sessions 15 to 22.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Fat mass, fat-free mass, whole-body and segmental skeletal muscle mass.	Body Composition Analyzer Seca mBCA 515. Individuals will be instructed to wear light clothing, and stand barefoot on the device, following manufacturer protocols. All assessments will take place at the same time of day.	Baseline and 10-weeks
Primary	Change in intra-abdominal fat	Body Composition Analyzer Seca mBCA 515. The measurement results allow estimating intra-abdominal fat in liters. Values <27 L are considered normal, >27 L to <43 L are considered elevated, and =43 L are considered high. Individuals will be instructed to wear light clothing, and stand barefoot on the device, following manufacturer protocols.All assessments will take place at the same time of day.	Baseline and 10-weeks
Secondary	Change in waist circumference	A flexible tape measure: Waist circumference will be measured following standard procedures, at the mid-point between the lower costal edge and the iliac crest. (Klein et al., 2007 https://doi.org/10.1093/ajcn/85.5.1197)	Baseline and 10-weeks
