Photobiomodulation (PBM) Therapy on Muscle Performance in Elderly Women

NCT04241991 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

Summary

The present project aims to investigate the acute and chronic effects of laser photobiomodulation (PBM) at 808 nm on muscle performance in physically active elderly women. The hypothesis of this study is that laser PBM would improve muscle strength (i.e., MVIC and 1RM) and endurance (i.e., repetitions-to-failure, blood lactate levels), functional capacity (i.e., short physical performance battery score), and rating of perceived exertion when compared with placebo laser.

Interventions

RADIATION

Active laser

Participants will receive laser irradiation on the rectus femoris muscle of both legs immediately before the test (trial 1) and training (trial 2) sessions. A researcher blinded to the treatment conditions will apply the irradiation on eight points distributed over the muscle belly, using a gallium arsenide aluminum (Ga-As-Al) laser (λ: 808 nm) equipment. The points will placed at 25, 35, 50 and 75% of the total distance between the anterior superior iliac spine and superior border of the patella, bilaterally, with 2 cm of distance between each point.
