Acute effect of phototherapy with light emitting diode (LED) on muscle and pulmonary oxygen consumption in men with diabetes mellitus and healthy

Abstract

Type 2 diabetes mellitus (DM2) is responsible to significant reduction in life quality due it negative impact in physical exercise capacity. Impairment in cardiopulmonary fitness and low oxygen uptake peak values (VO2peak) in exercise tests has been associated with many factors involved in diabetes complications. Phototherapy is a resource largely utilized due it action in biological systems and it may be adjuvant to exercise to improve muscular efficiency and increase aerobic capacity. Therefore, we hypothesized that this resource adjuvant with physical exercise may be benefit to populations with DM. Thus, the objective of this study will be evaluate the acute effect of phototherapy through light emitting diode (LED) on muscle and pulmonary oxygen uptake kinetics, even as, heart rate and arterial pressure kinetics in subjects with DM2, during dynamic physical exercise of constant workload and moderate intensity, to evaluate the systemic cardiovascular adjustments involving photo-stimulation application. Also, to verify the therapeutic potential of phototherapy in improve physical exercise tolerance and compare the results between DM2 and health individuals to see if the phototherapy effects are different between groups.
