Evaluación de fuerza como medida preventiva de lesión en musculatura isquiotibial, en futbolistas del club Madrigal en el año 2022.

Abstract

The imbalance of strength between the hamstrings and quadriceps is a risk factor in hamstring injury, the mechanism of injury occurs through a concentric action of the quadriceps and an eccentric contraction by the hamstrings, if the forces are not in harmony they give way After an injury, the functional mixed ratio (eccentric hamstrings/concentric quadriceps) is considered as a predictive measure of hamstring injury, both forces were measured by the 1rm test to determine whether or not there was a risk of hamstring injury. Objective: To evaluate the strength of the knee flexor and extensor groups as a preventive measure of hamstring injury, in soccer players of the madrigal club in the year 2022. Methodology: The present study has a descriptive scope with a quantitative approach, its design is not experimental. , with a nonprobabilistic sample of 40 athletes, the instruments used were a stopwatch, 1rm test, quadriceps extension machine and hamstring flexion machine. Results: The strength of the flexor and extensor muscles of the soccer players is unbalanced, 87.5% of the soccer players evaluated presented a risk of significant injury, in both legs, and only 12.5% did not present a significant risk. Conclusion: The implementation of an exercise protocol is considered vital to improve the balance of forces of soccer players since the data obtained through the applied tests are not adequate for good sports performance and have a high risk of injury.
