ANALYSIS OF THE LEVEL OF SWIMMING PHYSICAL TRAINING BASED ON LIMB STRENGTH

ABSTRACT Introduction Swimming has high criteria for physical ability and movement by athletes. Efficient strength training can not only improve the physical training level of athletes but also increase their sports ability. Therefore, it is an important link in swimming training. Objective Explore the effect of limb strength training on athletes’ fitness in swimming. Methods In this experiment, 20 swimmers majoring in physical education at a university were selected to undergo limb strength training for six weeks. Before and after the sports training, the indices such as thigh circumference, calf circumference, lower limb jumping ability, lower limb maximal strength, and lower limb balance ability of the athletes were measured, and the results of butterfly, backstroke, breaststroke, and freestyle in 50m main events were recorded. Results Efficient limb strength training can significantly promote the changes in athletes’ lower limb muscle strength, improve their endurance and explosive power, improve swimmers’ balance ability and movement stability, and significantly improve competitive swimming performance. Conclusion It is necessary to intensify physical strength training in athletes to improve their physical training level and economic performance. This plan can be considered very useful.
