Evaluación de fuerza y flexibilidad de musculatura flexora y extensora de rodilla dentro de un programa de lesiones por desbalances en rodilla, realizado en el Club Sport Dorados.

Abstract

The large number of injuries that usually occur in athletes are due to different mechanisms, but the most common are caused by muscular problems, in this case the imbalance of strength and flexibility between the knee flexor and extensor muscles. The strength of the quadriceps and hamstrings was assessed using the 1rm test in order to verify the amount of kilograms that the musculature can contract; and in turn, flexibility was evaluated using the Wells Test for the hamstrings and the Modified Thomas Test for the quadriceps. Objective: To assess the strength and flexibility of the knee flexor and extensor muscle groups. Methodology: It is a prospective study, quantitative approach, non-experimental design, with a sample of 20 soccer players, the instruments used were: 1rm test, Wells test, Modified Thomas Test, tape measure, goniometer, extensor machine for quadriceps, flexor machines for hamstrings. Results: By collecting data from Club Sport Dorados players, it was determined that the right leg (76.5kg in quads and 55kg in hamstrings) is slightly stronger than the left leg (76.5kg in quadriceps and 53.75kg in hamstrings), decreeing to be the most common dominant leg in soccer players. Conclusion: The presentation of a guide to prevent muscle injuries is essential for soccer teams. You can work on it, avoiding the presence of strength and flexibility imbalances in athletes.
