Primary Outcome Measures

Name	Time	Method
Maximum voluntary contraction (MVC) test[The MVC test will be carried on eight time: one week before the exercise protocol; immediately before and after exercise protocol; after 24 hs, 48 hs, 72 hs, 144hs and 196 hs of exercise.];Range of Motion. The range of motion (ROM) will be determined for the goniometer to measure the angle between the humerus and the radius. A semi-permanent marker will be used to identify the lateral middle point of the humerus, the lateral axis point of elbow joint, and the lateral middle point between radius and ulna. Flexed elbow joint angle (FANG) will be determined when the participant was asked to fully flex the elbow joint by touching his palm to the shoulder. Relaxed elbow joint angle (RANG) will be the angle when the elbow was extended (Chen et al. 2009).[The ROM will be evaluated during seven occasions: one week before the exercise protocol, immediatly after the eccentric exercise, after 24 hs, 48 hs, 72 hs, 144hs and 196 hs of exercise.]
