Summary

The prevalence of obesity in Brazil is one of the highest in Latin America. As an inflammatory disease, obesity needs to be treated, and one of the best interventions is exercise. This research aims to learn more about the effects of combining high-intensity training, recovery hypoxia, and taurine supplementation. To better understand these effects, the researchers will compare hypoxia and normoxia, as well as taurine and placebo, with all participants training in the same way. The researchers will also investigate mitochondrial respiration and food consumption to connect certain aspects of obesity with overall health.

Detailed description

Obesity is characterized by a chronic inflammatory state, often linked with elevated oxidative stress and mitochondrial dysfunction. While physical exercise can trigger inflammatory responses due to muscle damage, it also promotes significant bodily adaptations, particularly in body composition, physical fitness, and skeletal muscle tissue, including enhanced mitochondrial dynamics. Moderate hypoxia, when combined with exercise, further amplifies these benefits by increasing the expression of genes related to mitochondrial biogenesis, GLUT1 expression, and angiogenesis. Previous findings suggest that high-intensity physical activity not only improves cardiorespiratory capacity and alters body composition but also significantly elevates inflammation. Consequently, taurine, a supplement known for its anti-inflammatory properties and ability to reduce oxidative stress, should be considered to mitigate these issues and optimize the benefits of exercise and hypoxia. Based on these premises, it is hypothesized that the combination of taurine supplementation with physical training under recovery hypoxia may reduce the significant rise in pro-inflammatory cytokines, thereby enhancing the potential benefits of exercise and moderate hypoxia.

Interventions

Type	Name	Description
OTHER	Cycle ergometer	The initial part will last 5 minutes at low intensity, corresponding to "easy" by the RPE. The main part will be performed at the intensity of training zone 3 (100-110% of the Lan), lasting 5 minutes with a rest of 2.5 minutes between exercises. The intensity will be controlled by HR and RPE. The final part will last 3 minutes at low intensity, corresponding to "easy" by the RPE. The load progression occurred during the first four weeks, starting with 3 sets and adding 1 set per week. The intensity of each effort is 100-110%HRAnTh.
