Interventions
Device: Low-level laser therapy (808nm) and exercise
Registration Number
NCT01808716
Lead Sponsor
Universidade Federal de Sao Carlos
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.

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.
