Protótipo de sistema integrado de controle da restrição de fluxo sanguíneo no exercício físico

Abstract

The blood flow restriction (BFR) applied to resistance training (RT) presents itself as a promising alternative for rehabilitation and muscle gain, especially in vulnerable populations or with physical limitations. Recent literature has indicated that the use of RFS with intensities of 20-30% of 1RM demonstrates potential to induce physiological and hormonal adaptations similar to those of high-intensity training (70-85% of 1RM), such as the activation of AKT/mTOR pathways and the increase in GH and IGF-1 release. This study proposes the development of an integrated electronic-mechanical system prototype for the safe and controlled application of the RFS method, aiming to mitigate the risks associated with its practice, such as deep vein thrombosis, rhabdomyolysis, neuropathies and discomfort. The developed device includes sensors for real-time monitoring of physiological parameters, such as heart rate, oxygen saturation and blood pressure, as well as systems for controlling occlusion times and pressure. The application of uniform and adjustable pressures was validated through laboratory tests, ensuring the safety and effectiveness of the method. The system also has safety mechanisms in cases of emergency, such as automatic shutdown and intervention by a specialist professional, reducing the risks of adverse events. Thus, the developed device contributes to the safe application of RFS, being a viable and effective tool for rehabilitation and fitness programs.
