Gedetailleerde beschrijving
This is a clinical, randomized, controlled placebo and double-blind study. Forty-eight participants performed muscular training protocol. Subjects practiced a protocol training with 60% of the load followed by 80% of the load, measured through 1-repetition maximum test, in all sessions of the training protocol. The training protocol consisted in performing 3 sets of 7 repetitions with 60% of 1-RM, and 4 set of 7 repetitions with 80% of 1-RM. This protocol was performed in every sessions, three times a week, employing leg press and leg extension machines.
Phototherapy, active or placebo, were applied in 6 different points of anterior muscle of the thigh before and after each training session. Only one investigator, that did not participate in any phase of the assessments and trainings sessions, knew about what program is active or placebo in phototherapy device. Randomisation carried out by a simple drawing of lots (A, B, C, or D) in the first visit. The phototherapy unit emitted the same sound regardless of the program used, active or placebo. Either strength training lasted 12 weeks and assessments were performed at baseline, 4, 8 and 12 weeks. There were evaluated maximal voluntary contraction (MVC), concentric torque, bilateral thigh perimetry and 1-repetition maximum test (1-RM).

Experimenteel: Group A - Active or Placebo Phototherapy
Participants enrolled in this group performed a training protocol for 12 weeks with light application before and after the exercise protocol. The phototherapy device was divided in program 1 and program 2. One of these programs consisted in active phototherapy and the other placebo. The subjects allocated in group A, received program 1 before strength training, and the same program 1 after training. |
