Active Comparator

Arm Label

Low-level laser therapy (LLLT)

Placebo low-level laser therapy (Placebo)

Arm Description

Use of low-level laser therapy (LLLT) to induce a muscle fatigue resistance in intense exercises

Use of low-level laser therapy (LLLT) placebo to induce a muscle fatigue resistance

Outcomes

Primary Outcome Measures

Maximum repetitions
Evaluation of maximum repetitions of knee flexion-extension in isokinetic dynamometer. Volunteers were assessed on Monday (pre evaluation - baseline), on Wednesday performed a session of exercises and on Friday were assessed again (final evaluation).

Secondary Outcome Measures

Median Frequency
Evaluation of median frequency by surface electromyography of quadriceps femoris muscles during maximum repetitions of knee flexion-extension in isokinetic dynamometer. Volunteers were assessed on Monday (pre evaluation - baseline), on Wednesday performed a session of exercises and on Friday were assessed again (final evaluation).
