Effect of Muscle Pain in Late Cold Water Immersion, Muscular Recruitment, Postural Control Dynamic and Sleep Quality

Objective: To evaluate the effect of cold water immersion in elayed onset muscle soreness, muscle recruitment, dynamic postural control and quality of sleep in young soccer players. Methods: The sample will consist of 28 soccer players between 18 and 21 years of the same football club and with the same routine practices and games. At first athletes will respond to the IC and will be submitted to the test of a repetition maximum. After three days the athletes will analysis of muscle recruitment by electromyography and dynamic posture control through the force platform both during the time of shooting, moreover, will respond to scale the quality of sleep the previous night and one on pain, then they are instructed to perform a fatigue protocol for the quadriceps and then will be randomized to one of four intervention groups: cold water immersion, submersion in water at room temperature, or active recovery control. The same APPRAISAL be remade into three new moments, 24, 48 and 72 hours after the fatigue test. Hypothesis: The variables will be considered: Pain intensity in the quadriceps muscle, quality of sleep the night after intervention protocol, electromyographic analysis of the rectus femoris, vastus medialis oblique and vastus lateralis at the time of shooting, as well as postural control when the shot off. It is intended to establish the best way of recovery of late quadriceps muscle pain and contribute to the clinical practice of active recovery or rest in young soccer players.
