Experimental: Active phototherapy group
(n=12) Phase 2 training + active phototherapy Dosage applied was 30J per site (180J per muscle) to six sites on the quadriceps The MR4 LaserShower 50 4D emitter (MultiRadiance Medical, USA). The optical power was calibrated before irradiationin each participant using a Thorlabs thermal power meter(Model S322C, Thorlabs, Newton, NJ, USA).
Photobiomodulation or photobiostimulation, this technique is the application of monochromatic light that can influence cellular activity through inhibition or stimulation of chemical and biological functions.
Placebo Comparator: Placebo group
(n=14) Phase 2 training + placebo phototherapy group
The same procedures as in the active phototherapy group was applied to the placebo group; however, the emitter was disabled. The device was emit the same sounds regardless of the programmed mode (active phototherapy).
non-treatment control group
(n=13) Phase 2 training + control group
Other: Passive recovery
Participants was remain sat for passive recovery supervised by an independent therapist during the period when the other groups are received recovery strategies.
- Effects of phototherapy on adaptation and change of cardiac Autonomic modulation. [ Time Frame: Baseline (captation of hear rate variability for 20 minutes) before 6 weeks (captation of hear rate variability for 20 minutes) and before 12 weeks (captation of hear rate variability for 20 minutes) ]Analyzed and compare the effects of phototherapy with different light sources and wavelengths applied during training combined at heart rate variability
- Effects of phototherapy on recovery of cardiac Autonomic modulation. [ Time Frame: During training sessions with higher energetic spending leaving for the last two weeks, composed of higher intensity - (captation of hear rate variability for 1 hour on phase 1 and phase 2). ]Compare the effects of phototherapy with placebo group and control group at recovery after exercise of heart rate variability.
- Effects of phototherapy on tracking daily of cardiac autonomic modulation. [ Time Frame: daily, after exercise and before exercise (captation of hear rate variability for 7 minutes) ]Analyze and compare the change in the indices of heart rate variability in tracking daily after combined training of sprints and squats
