Brief Summary

Hormonal fluctuations present during the ovarian cycle may have a strong influence on physiological and psychological aspects on physical performance in women. The aspects surrounding performance and ovarian cycles in women during different phases of the cycle, are still current and should be debated in the literature, as the available evidence has conflicting results. In addition to the above, new ergogenic methods have been studied to improve the sports scenario in different populations. Research on the use of ergogenic electrophysical resources so that hormonal effects may possibly be mitigated, allowing women to use this resource and improving their physical performance is still scarce in the current literature.

Study Arms (2)

G-FBM-CEN

EXPERIMENTAL

Photobiomodulation application in women of endogenous cycle. Antares® equipment (IBRAMED, Amparo-SP, Brazil) will be used, by means of a cluster, with two wavelengths (13 LEDs of 630 nm, 300 mW + 13 LEDs of 850 nm, 500 mW), being its area of 80 cm² contact, acting 180 J of energy being applied at 15 points on each thigh - 9 in the anterior region and 6 in the posterior region, in addition to 2 points in the gastrocnemius.

Device: Photobiomodulation

G - Sham - CEN

SHAM COMPARATOR

Sham Photobiomodulation (disabled) application in women of endogenous cycle. The procedure and equipment will be the same as for the experimental groups, however no dosage will be applied: Antares® equipment (IBRAMED, Amparo-SP, Brazil) will be used, by means of a cluster, with two wavelengths (13 LEDs of 630 nm, 300 mW + 13 LEDs of 850 nm, 500 mW), being its area of 80 cm² contact, with 0 J of energy being applied at 15 points on each thigh - 9 in the anterior region and 6 in the posterior region, in addition to 2 points in the gastrocnemius.

Device: Photobiomodulation

Interventions

Application of light at specific wavelength for interaction with biological tissue

Masking Details
The randomization and allocation of participants will be performed by a researcher who will not have access to evaluations and data collection. The interventions will be carried out by the researcher who made the allocation, and data collection by a second researcher, who is blinded to the allocation of the participants. Participants will not know about their allocation during the collection process and during the intervention they will wear a mask covering their eyes.
Purpose

Intervention Model
PARALLEL
Model Details: The randomization and allocation of participants will be performed at beginning of the project, allocating the participants in 2 groups: * Endogenous ovarian cycle Photobiomodulation Group(G-FBM-CEN); * Endogenous ovarian cycle Sham Group (G - Sham - CEN).
