Preventive Exercise Program for Adolescent Futsal Players.

The main aim of this study is to analyse the effect of a preventive exercise program (INSPIRE: Indoor Sports Injury Prevention) on the lower-limb injuries in adolescent futsal players. For this purpose, 26 adolescent futsal players will be recruited, and after baseline evaluation, they will be randomized either the standard care, that will undergo the standard strengthening program developed each year in their team, or the experimental group, that will undergo the INSPIRE program, based on three stages (motor control, strength and endurance, and propioception and neural workout). Both groups will develop a 8-week intervention. Regarding the evaluation, the participants will have three evaluations: baseline, 4 weeks, and 8 weeks, and they will complete validated questionnaries (Overuse Injury Questionnaire, and Return to Play Score), together with functional tests (Y-Balance Test), strength testing using a dynamometer, and motor control testing using force plates.

Treatment and study plan

Exercise

Other

INSPIRE PROGRAM. Exercise program based in three stages: 1. Motor control and motor relearning: based on basic movement patterns and muscle chains, together with selective activation of muscles such as gluteus, aductors, hamstrings, quadricepts, gastrocnemius, and peroneus, using closed kinetic chain exercises. 2. Strength and endurance: based on strengthening the aforementioned muscles, using pushing and reception exercises, together with long efforts. 3. Propioception and neural workout: based on the training on propioception in stable and unstable surfaces, together with exercise of acceleration, decceleration, direction changes, and dual tasks.
