Cryotherapy and Laser Therapy on Muscle Damage

Universidade Federal do Rio Grande do Norte60 enrolled

Overview

This study propose investigate the effect of cryotherapy and laser therapy in response to strenuous exercise-induced muscle damage on the biceps brachii muscle (muscle of the arms). All the individuals underwent to an strenuous exercise protocol (2 series of 10 contractions of non-dominant elbow flexors) and three assessments (pre, post and 48hr after the exercise), composed of pain sensation, measure of the strength and muscle activation.

Outcomes

Primary Outcomes

Pain sensation

Through the VAS (visual analogue scale).

Time frame: Within the first 3 days

Secondary Outcomes

Strength

The strength will be measure through isokinetic dynamometry and the variables analyzed will be peak torque normalized for body weight and power.

Time frame: Within the first 3 days

Muscle activation

Measured by surface electromyography.

Time frame: Within the first 3 days
