Photobiomodulation by low-intensity LEDs was performed using a non-commercial light-emitting array (cluster) of 69 LEDs. This device contains 35 LEDs that emit light in the red range (630 ± 10 nm
10 mW
0.2 cm2) and 34 LEDs in the infrared range (830 ± 20 nm
0.2 cm2) arranged interchangeably in a circular emitting area of ??40 cm2. The device was in contact with the skin at 90 ° and with light pressure, for 90 seconds at each point. The photobiomodulation

Primary
| Measure | Time frame |
|---|---|
| Evaluate the pulmonary function index, using the forced vital capacity spirometry (FVC) method expressed as a predicted percentage (%). We will observe the evaluation and characterization of the behavior of the cardiorespiratory responses studied in the volunteers selected for the research, allowing to clarify the influence of photobiomodulation on them.;Evaluate the pulmonary function index, using the forced expiratory volume spirometry method in the first second (FEV1) expressed as a predicted percentage (%). We will observe the evaluation and characterization of the behavior of the cardiorespiratory responses studied in the volunteers selected for the research, allowing to clarify the influence of photobiomodulation on them.;Evaluate the pulmonary function index, using the spirometric maneuver method Ratio between forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC), called the "Tiffeneau index" expressed in predicted percentage (%). We will observe the evaluation and characterization of the behavior of the cardiorespiratory responses studied in the volunteers selected for the research, allowing to clarify the influence of photobiomodulation on them.;To evaluate the pulmonary function index, using the method of maximum voluntary ventilation (VVM) spirometric maneuver expressed in liters per minute (l / min).
