NCT03879226 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60

No results posted yet for this study

Summary

In last years it has been demonstrated that photobiomodulation therapy (PBMT) has ergogenic effects. However some key aspects, such as the potentially beneficial effects of PBMT during the detraining period still remain unknown.

Therefore, the aim of this project is to evaluate the effects of PBMT applied before and after aerobic training sessions and during the detraining period.

Conditions

  • Aerobic Endurance

Interventions

DEVICE

PBMT

PBMT will be applied bilaterally using the direct contact method with light pressure on the skin at different sites, namely 9 sites on the knee extensor muscles, 6 sites on the knee flexor muscles, and 2 sites on the plantar flexor muscles. A 12-diode cluster, with 4 905-nm laser diodes (12.5W peak power for each diode), 4 875-nm LED diodes (17.5 mW mean power for each diode), and 4 640-nm LED diodes (15 mW mean power for each diode), manufactured by Multi Radiance Medical® (Solon, OH, USA), will be used to apply the PBMT. The dose used for the applications during the training and/or detraining periods will be 30 Joules (J) per site (510 J per lower limb). PBMT will be applied before and after each training session and during the detraining period, depending on the group to which the volunteers are allocated.

DEVICE

Placebo

Placebo will be applied bilaterally using the direct contact method with light pressure on the skin at different sites, namely 9 sites on the knee extensor muscles, 6 sites on the knee flexor muscles, and 2 sites on the plantar flexor muscles. The placebo PBMT will per performed using the dose of 0 J per diode. The sounds and signals emitted from the device as well as the information displayed on the screen will be identical, regardless of the type of treatment (active or placebo). Placebo will be applied before and after each training session and during the detraining period, depending on the group to which the volunteers are allocated.
