Terapia por fotobiomodulação associada ao treinamento resistido em mulheres idosas fisicamente ativas – ensaio clínico, randomizado, placebo-controlado

Abstract

The elderly population has increased in developed countries like Brazil. Physical activity plays an essential role in mitigating the harmful effects of aging. Photobiomodulation therapy (TFBM) has shown benefits in improving muscle fatigue, late muscle pain, caused by resistance training. The objective of this study was to evaluate the effects of incorporating photobiomodulation therapy in a resistance training protocol in relation to muscle fatigue and muscle damage in physically active elderly women. Thus, 20 physically active elderly women, practitioners of aqua aerobics, with medical clearance, completed anamnesis participated in the study. The volunteers were allocated into three groups: Group 1 exercise and active TFBM, G2 exercise and placebo TFBM and CG control group. Interventions were performed twice a week on alternate days for 8 weeks. The volunteers were evaluated before and after the proposed interventions, in relation to the functional capacity assessed using the six-minute walk test (6MWT) and Analysis of Creatine kinase and lactate dehydrogenase. Analyzing the variables studied, no statistically significant differences were found in the intra- and inter-group analyzes over time.
