Brief 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.

Outcome Measures
Primary Outcomes (1)
Time until exhaustion.
The time until exhaustion will be measured by the software of ergospirometry system.
16 weeks - 4 weeks after completing the training (detraining period).
Secondary Outcomes (3)
Time until exhaustion.
4, 8, and 12 weeks after starting the training period.
Maximum oxygen consumption (VO2).
4, 8, and 12 weeks after starting the training period, and at 4 weeks after completing the training (detraining period).
Fat percentage.
4, 8, and 12 weeks after starting the training period, and at 4 weeks after completing the training (detraining period).
Study Arms (4)
PBMT + training/ PBMT + detraining
EXPERIMENTALPBMT applied before and after the aerobic training sessions (12 weeks, 3 times a week) and PBMT applied during the detraining period (4 weeks, 3 times a week).
PBMT + training/ placebo + detraining
EXPERIMENTALPBMT applied before and after the aerobic training sessions (12 weeks, 3 times a week) and placebo applied during the detraining period (4 weeks, 3 times a week).
Placebo + training/ PBMT + detraining
EXPERIMENTALPlacebo applied before and after the aerobic training sessions (12 weeks, 3 times a week) and PBMT applied during the detraining period (4 weeks, 3 times a week).
Placebo + training/ placebo + detraining
PLACEBO COMPARATORPlacebo applied before and after the aerobic training sessions (12 weeks, 3 times a week) and placebo applied during the detraining period (4 weeks, 3 times a week).
Interventions
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.
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.

- Masking Details
- A researcher will program the device (placebo or PMBT) and will be instructed not to inform the volunteers or other researchers as to the type of treatment (PMBT or placebo). Therefore, the researcher responsible for the treatment will be blinded to the type of treatment being administered to the volunteers. 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 (placebo or PBMT).
