A method to assess eccentric hamstring strength in 15 to 16-year-old football players
T. Georgiev
Резюме: Objective: The aim of this study was to test the reliability of a method developed to assess the eccentric strength of the hamstrings. Materials and methods: The study contingent was football players aged 15-16 years (n = 20). Each participant had two distinct testing sessions over the course of 48 hours on two different days in order to assess the experimental method's reliability. Intraclass correlation coefficient (ICC) was used to assess test-retest reliability and to check the reproducibility of the data from the two sessions. Results: The results of the two sessions showed an ICC of 0.81 for the right leg and 0.89 for the left, indicating the reliability of the experimental method and a very good estimate of the reproducibility of the data in assessing eccentric strength of the hamstrings in 15-16-year-old football players. The confidence limits at a 95% confidence interval were 0.546 - 0.929 for right leg and 0.677 - 0.953 for left leg, respectively. The standard error of measurement was 35.18 (N) for right leg and 36.16 (N) for left leg. The minimum detectable change was 68.97 (N) for the right leg and 70.88 (N) for the left leg. Discussion: Muscle strains, in particular those of the hamstrings, are the most common injuries in football. Many risk factors determine the occurrence of this injury. One of the main and most studied ones is the eccentric strength of the hamstrings. Conclusion: The reliability of the method allows its application as a tool for assessing the eccentric strength of the hamstrings. By registering deviations from reference values and between leg asymmetries in eccentric strength of the hamstrings, the device can be successfully used for prevention and functional diagnosis, as well as a screening tool in the recovery phase after an injury. Additionally, because the system generates real-time strength data it could be used for biofeedback as part of rehabilitation and strengthening programs.
