Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluation of peak torque (Newton x meter / body weight) in muscle performance in three maximal isometric voluntary contraction test (60 degrees of knee flexion) of knee extensors in isokinetic dynamometry after photobiomodulation therapy | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluation of fatigue index, number of repetitions, total work, acceleration time (seconds) and time (seconds) to peak torque in the fatigue test during 60 seconds for performing flexion and extension in isokinetic dynamometry (240 degrees per second) after photobiomodulation therapy;Evaluation of torque (Newton x meter), time of peak torque (seconds) and power (watts) in three maximal isometric voluntary contraction test (60 degrees of knee flexion) of knee extensors in isokinetic dynamometry after photobiomodulation therapy;Evaluation of delayed onset muscle soreness by numerical rating scale (0-10) and general perception of pain (map of pain) between 24, 48 and 72 hours after isokinetic dynamometry and running agility test;Evaluation of the mean and best attempt (seconds) in the running agility test after isokinetic dynamometry;Evaluation of perceived recovery status between 24, 48 and 72 hours after isokinetic dynamometry and running agility test | — |
