تأثیر هشت هفته تمرین آماده‌سازی اختصاصی پرفشار بر متغیرهای منتخب بیومکانیکی و آنتروپومتریکی کشتی‌گیران جوان نخبه

Objective: The aim of this study was to investigate the effect of eight weeks of high intensive exercise on selected biomechanical and anthropometrical variables in elite wrestlers. Methods: Sixteen young wrestlers (age 19.1±1 years and weight 74.9±17.3 kg) attending the national Greco-Roman camps participated in this study. Biomechanical and anthropometrical variables included weight, body fat percentage, body mass index, balance, general body speed and acceleration, active range of motion of the joints, upper and lower extremities power and hand grip strength. These variables were measured before and after 8 weeks (67 sessions) of special exercise training. The normality of data was checked by Kolmogorov- Smirnov normality measure and data were analyzed with Paired- samples t-test to compare variables before and after training program, with a significance level of (P≤0.05). Results: Results showed that there were significant differences between weight, body fat percentage, body mass index, semi-dynamic balance in the medial and anterior-medial directions, upper extremities power, the range of lateral flexion to the right of the neck and hip flexion of pre and post-test. Conclusion: Based on the results, it seems that applied training program had main effect on biomechanical and anthropometrical variables such as weight, body fat percentage, body mass index, power, balance and active range of motion of elite wrestlers that will increase the qualitative athletic performance.
