Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
Pain sensation	Within the first 3 days	Through the VAS (visual analogue scale).

Secondary

Measure	Time frame	Description
Strength	Within the first 3 days	The strength will be measure through isokinetic dynamometry and the variables analyzed will be peak torque normalized for body weight and power.
Muscle activation	Within the first 3 days	Measured by surface electromyography.
