Effects of Two Virtual HIFCT Programs in Adults With Abdominal Obesity (HIFCT-V)
Effects of Two Virtual High-intensity Functional Circuit Training Programs on Intra-abdominal Fat, Body Composition, Health-related Quality of Life, and Some Components of Physical Fitness in Adults With Abdominal Obesity
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.

Intervention / Treatment |
|---|---|
|
Experimental: HIFCT-S
For sessions 7 to 14, a concentrated circuit divided into four blocks of three exercises will be carried out, with a duration of 40 seconds per exercise with no rest between them.
A rest of 120 seconds will be given at the end of each block, and a rest of the same time at the end of the first set.
Two sets will be executed, which will result in a total time of 30 minutes including rest.
For sessions 15 to 30, four blocks of two exercises will be performed, with a duration of 60 seconds per exercise, with no rest between them.
The rest between blocks will be 120 seconds.
Two sets will be performed, for a total time of 30 minutes including breaks.
The exercises will be performed at speeds between 35 and 75 bpm.
The intensity will be between 80% - 90% (8-9 RPE).

Active Comparator: HIFCT-P
For sessions 7 to 14, a concentrated circuit divided into two blocks of six exercises will be carried out, with a duration of 60 seconds per exercise with no rest between them. A rest of 120 seconds will be given at the end of each block, and a rest of the same time at the end of the first set. Two sets will be executed, which will result in a total time of 30 minutes including rest. For sessions 15 to 30, five blocks of two exercises will be performed, with a duration of 120 seconds per exercise, with no rest between them. The rest between blocks will be 120 seconds. The total time per block is four minutes, for a total time of 30 minutes including breaks. The exercises will be performed at speeds between 35 and 75 bpm. The intensity will be between 80% - 90% (8-9 RPE). |

Change in intra-abdominal fat
Time Frame: Baseline and 10-weeks
|
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.
