Programa FIFA11+ e seus benefícios sobre o equilíbrio postural e força muscular isocinética de joelho em atletas de futsal sub 13

Abstract

To evaluate the effects of the FIFA 11+ program on postural balance, isokinetic muscle strength of knee and functional performance of the lower limbs, in indoor soccer players U 13. Methods: Participated male players, age 11 to 13 years, team members in regular training. Balance was assessed using computerized dynamic posturography (CDP), including sensory organization test (SOT), made up of six conditions in which condition 1, 3 and 6 evaluates the visual, proprioceptive and vestibular system, the condition 2 and 5 evaluates the proprioceptive and vestibular system and the condition 4 evaluates the proprioceptive system. The muscle strength of the knee was measured by isokinetic dynamometer Biodex System Pro 4, the speed 60o / s and 180 ° / s, and were evaluated peak torque (PT), total work (TT), power (POT) and agonist / antagonist ratio. The evaluation of the functional performance of the lower limbs was analyzed by tests: Single Hop Test; Triple Hop Test; Cross-over Hop Test and Timed Hop Test. After the athletes participated in the FIFA11 + program for 21 weeks, often 2 times a week and last approximately 20 minutes before the beginning of each regular training of athletes. There was an improvement in postural balance of the post-intervention athletes, the conditions 1, 2 and 6 of the SOT. As the isokinetic muscle strength, an increase in PT and TT in knee flexors and extensors, the speed 60o / s and 180 ° / s, POT extenders in the dominant member, POT flexors in the non-dominant limb to 60o / s POT flexors the dominant limb to 180 ° / s. There was also improvement in functional performance tests, especially on the dominant side. The FIFA 11+ protocol contributed to the improvement of postural balance, functional performance and increased muscle strength of knee in indoor soccer players U 13.
