Effects of Photobiomodulation and Deep Water Running Training in Subjects With Low Back Pain.

The LED application will be performed before GTL training sessions and will be applied through the spot method with direct contact of the equipment over the irradiated site for 30 seconds. The application will be in four points in the lumbar region, above the gluteal region, with an angle of 90 ° in relation to the cutaneous surface. A wavelength of 660 to 850nm will be used with a frequency of 0 to 1500 Hz and energy irradiated of 0.9 J of each diode totaling 43.2J (48 diodes).

The training sessions will be monitored based on the subjective perception of exertion of the session (PSESession) (FOSTER, 1998), and heart rate. There will be two types of training: continuous and interval training. The sessions of the training group (GT) and group training + LED (GL) will be preceded by a warm-up of 15 minutes. Participants in the two training groups will undergo weekly training twice weekly on non-consecutive days during four weeks. Continuous training will be 30 minutes at 70% to 80% of maximum heart rate, and interval training will be performed 30 minutes at 100% maximum heart rate of laced racing with fixation of an elastic tube in the floating vest, 30 seconds of intense running and 30 seconds interval. The LED off will be performed before training sessions.
