Exploring the influence of a 10-week specific detraining on injury risk factors among elite young wrestlers: a prospective study
Abstract Extended periods of inactivity in sports can impact athletes’ performance and overall well-being. The current study examined the effects of a 10-week wrestling -specific detraining period on the isokinetic strength of knee and shoulder flexor and extensor muscles, knee proprioception, and d...

| description | Abstract Extended periods of inactivity in sports can impact athletes’ performance and overall well-being. The current study examined the effects of a 10-week wrestling -specific detraining period on the isokinetic strength of knee and shoulder flexor and extensor muscles, knee proprioception, and dynamic balance among young male elite wrestlers. This prospective study included 63 male wrestlers : age (19.33 ± 3 years), height (174.32 ± 6.8 cm), weight (80.21 ± 22.01 kg), BMI (25.34 ± 5.89), fat percentage (13.25 ± 5.80) in Tehran’s premier wrestling league. Baseline measurements, including isokinetic strength of knee and shoulder flexors and extensors, knee proprioception, and dynamic balance, were evaluated using the Biodex 4 dynamometer and Biodex balance meter, respectively, and repeated after a 10-week lockdown during the COVID-19 pandemic at Shahid Beheshti University, Tehran, Iran. Statistical analysis utilized dependent t-tests to compare the results. Significant differences were observed in the isokinetic strength of shoulder and knee flexor and extensor muscles at angular speeds of 60, 180, and 300 degrees per second after 10 weeks of detraining (p < 0.05). Additionally, a decrease in the accuracy of knee joint proprioception was found, including active angle restoration at angles of 30°, 60°, and 90° and passive movement detection in flexion and extension at a 90-degree angle (p < 0.05). Moreover, dynamic balance significantly reduced in the single-leg form (p < 0.05). The findings revealed that wrestling -specific detraining period can significantly affect musculoskeletal and proprioceptive parameters in wrestlers, increasing the risk of injuries and reducing the performance and physical fitness. Consistent engagement in wrestling -specific training is essential to ensure optimal fitness and overall well-being, particularly for elite athletes. |
