Valoración de la fuerza muscular del cuádriceps y flexibilidad de la musculatura isquiotibial, como medida preventiva en las lesiones de rodilla, en los jugadores de futbol de entre 14 a 16 años de edad, pertenecientes a la escuela formativa Junta de Beneficencia de Guayaquil.

Abstract

Soccer is one of the important social practices of collective identity that transcends national boundaries, however, there are several injuries in the sport that threaten fitness and peak performance, including knee injuries Objective: To determine quadriceps muscle strength and flexibility of the hamstring musculature through tests. Materials and methods: Descriptive, observational, cross-sectional study. Data collected through the Daniels test, Back-saver sit-and-reach test, to 84 soccer players of the Escuela Formativa Junta de Beneficencia de Guayaquil, which allowed evaluating the muscular strength of the quadriceps and flexibility of the hamstring musculature. Results: The results obtained by means of the strength tests determine that the risk of injury, for the population of 14 year olds present a percentage of 69% of moderate weakness (4+) in the left quadriceps 69% of moderate weakness (4+), those of 15 year olds, 60% with moderate weakness (4+), 67% with moderate weakness (4+), 67% moderate weakness (4+), those aged 16 years presented 54% showed moderate weakness (4+), 50% presented moderate weakness (4+), as for flexibility In the age of 14 years 61% showed poor flexibility of the right musculature. Conclusion: quadriceps strength and hamstring flexibility are unbalanced, which leaves vulnerable to future knee injuries, it is important to consider the intention of proposing a guide of quadriceps strengthening exercises and stretching of the hamstring musculature to avoid knee injuries in players.
