Development And Application Of YZ-4the Fourth-Generation Swimming Simulated Kick Training Equipment And Apparatus

Competitive sports are swimming in the physical categories of projects, the quality of special strength training is particularly important. The conventional training methods and means have been difficult to form body function of the depth of stimulation on today’s sports training practice,with special training equipment to meet or exceed the game to help the body function of stimulus intensity exercise training is currently research topics in the field.The issue of lower extremity strength training for swimmers means of single status and the basis of preliminary studies to develop a new type of lower extremity strength training equipment-swimming training device simulation kick. The structure of the training equipment used in mechanical engineering rocker structure, mechanical principle of the graphical method to determine the crank, connecting rod and rocker of the size and location of the turning pairs, and the difference in length according to the design of the athletes conditioning device. The training device can dynamically simulate swimming movements, strong sense of reality; using digital display technology, through the tension sensor, incremental encoder, data acquisition cards, monitors and other direct acquisition, management training information, shows athletes training in real-time indicators.Lower extremity strength training on new equipment for a quick kick frequency of testing, the limit load test, limit compression test, test results showed that:equipment in high-speed cases, the components operating normally, no noise, noise, trainers affordable Players the impact of fast frequency kick; equipment12kg more than the maximum load capability limit load of athletes, can meet the training needs of athletes;5minutes over the limit more than the same time pressing and pressing the destructive pendulum experiment, working conditions, equipment good structural strength than the athletes on the limit, to protect the use of safety devices.The new training equipment and Monark bicycle power compared to the experimental test results show that the two curves of similar power and speed are increased as the slope of increased load, and further shows that the new training equipment design is reasonable.New training equipment training and conventional training methods were compared, results showed that exercise training intensity higher than the water device training intensity, the former on the body to stimulate the deep; trainer and water training in the implementation of the same strength, the same training program, blood lactate and creatine kinase had decreased to some extent, explain the training of new training device is better than conventional method of training.
