Summary

Introduction. The most popular injuries in volleyball are the ones who occur in knee joints, due the jumps and landings that happen through the game. For this reason there is a high index of loss of stability because of the dynamic valgus during the landing, a loss of balance and a decrease of power during the jumps. Objective. Evaluate the effectiveness of neuromuscular training in combination with strengthening of CORE in the improvement of knee joint stability, balance and power in vertical jump in volleyball players from 18 to 25 years old. Study design. Randomized, multicenter, single-blind clinical study with follow-up period. Methods. The study will be realized with an initial sample of 30 players, which in a random way, will be divided into two groups: experimental and control. It will be realized an initial evaluation where sociodemographic, anthropometric and clinical measures will be taken, and the study variables: knee joint stability (single leg squat test), balance (star excursion balance test) and vertical jump (sargent jump test). The intervention will last six weeks, with two sessions per week of approximately twenty minutes each. Expected results. The investigators expected to observe improvement in the stability in the knee joint, balance and power in the vertical jump in 18-25 years volleyball players that have received a neuromuscular training with strengthening of CORE.

Interventions

Type	Name	Description
OTHER	Experimental	The player will perform exercises of balance, stability, and strengthening of the abdomen, back and gluteus. All these exercises will be carried out in first instance on flat surfaces and later on unstable surfaces to increase the difficulty of it. The training will be done in different levels of difficulty, once the participant managed to master the initial level, advance to the next level to complete the three levels of difficulty during the 6 weeks of training. There will be 3 repetitions of each exercise with a duration of one minute and breaks of 30 seconds between each repetition and 2 minutes of rest between exercises. The duration of the intervention of the experimental group will last 20 minutes
OTHER	Control	Neuromuscular training will be applied through balance and stability exercises on both flat and unstable surfaces. There will be 3 repetitions of each exercise with a duration of one minute and breaks of 30 seconds between each repetition and 2 minutes of rest between exercises. The duration of each session of the control group is 10 minutes.
