Summary

Background: Volleyball players constantly perform vertical jumps, the higher the height of the jump is better sports performance of these players. Several methods have been tested to improve jumping performance in these players. It will be investigated the addition of electrical stimulation and phototherapy to jump training in volleyball athletes. DESIGN: randomized controlled trial. METHODS: This study will be conducted with 36 male athletes volleyball with minimum experience of 12 months sport. Will be randomized and assigned to 3 groups (control group, NEMES group and group phototherapy). All 36 healthy volleyball athletes who passed the initial selection and agreed to participate in the study, conduct a muscle strength and jump training program, which is held in both legs simultaneously. The 12 healthy athletes electrical stimulation group will perform the same training program described above, but strength training is associated with electrical stimulation. The 12 healthy athletes participating in the phototherapy group will undergo a phototherapy protocol before performing the strength and jump training. All selected participants will undergo an assessment of muscle strength of knee extensors and evaluate the jump. These evaluations were baseline, 6 weeks and 8 weeks after baseline.
