Abstract

Background: Optimal muscle strength is a critical factor influencing performance and reducing injuries among wrestlers. This study aimed to investigate the effects of an eight-week modified FIFA 11+ warm-up program on the isokinetic knee strength of elite wrestlers.
Methods: In this quasi-experimental study, 27 elite wrestlers were selected as participants and divided into two groups: training (n = 13) and control (n = 14). The training group performed the modified FIFA 11+ warm-up program for 8 weeks, which included aerobic, stretching, plyometric, strength, balance, and speed activities. The control group continued their traditional training routines. The strength of the knee flexor and extensor muscles and the flexor-to-extensor strength ratio were assessed using a Biodex Isokinetic System Pro3 at pre-test and post-test phases. Data were analyzed using analysis of covariance (ANCOVA) in SPSS software (P < 0.05).
Findings: The results of this study indicated that concentric strength of the knee flexor muscles at both angular velocities of 60°/s and 120°/s (P = 0.001), eccentric strength of the knee flexor muscles at 60°/s (P = 0.044) and 120°/s (P = 0.003), and both concentric (P = 0.002) and eccentric (P = 0.003) strength of the knee extensor muscles at 120°/s were significantly greater in the post-test compared to the control group. Furthermore, the hamstring-to-quadriceps strength ratio was notably higher in the post-test compared to the control group (P = 0.001).
Conclusion: The modified FIFA 11+ program increased knee strength factors, so it can be recommended that they be incorporated into warm-up routines to enhance strength and performance and also potentially contribute to injury prevention.
