Brief Summary:
The study hypothesis is a decreased muscle damage induced by exercises when low-level laser therapy is applied on body muscles before exercises.

Condition or disease Intervention/treatment Phase
Healthy Device: Low-level laser therapy (808nm) and exercise Not Applicable

Detailed Description:
The study assessed males submitted to exercise to induce muscle damage. Creatine kinase levels in blood was quantified in order to identify the magnitude of muscle damage.
