Morphofunctional indicators of wrestlers during the preparatory period of training

Wrestling requires the comprehensive development of physical qualities, including high muscle strength, anaerobic power, and endurance. Assessing the functional profile of wrestlers, particularly the ability of muscles to rapidly generate force (rate of force development), is important for the objective evaluation of strength potential, identification of overtraining, and injury risk. The purpose of the study is to identify the characteristics of strength and power in belt and koresh wrestlers during the preparatory period, with a focus on the rate of force development of leg extensors and its relationship to the level of sports mastery. Research methods and organization. The study involved athletes engaged in belt wrestling and koresh belt wrestling. Anaerobic power was assessed using the Monark 894 E ergometer, and isokinetic and isometric testing of knee joint extensors was conducted on the Knee-Pro AntexLab apparatus. Measurements included maximum torque, rate of force development, time to peak torque, and anthropometric indicators. Research results and conclusions. The most informative indicator was the inverse correlation between the rate of force development in isokinetic mode at 30°/s and the level of sports mastery. A positive correlation was noted between the time to peak torque and mastery level, indicating better muscle recruitment ability among more qualified wrestlers. The study demonstrated that a high level of sports mastery in belt wrestling and koresh may be accompanied by a reduction in the rate of force development, which is likely associated with enhanced neuromuscular control.
