Research On The Application Of "Liquid Weight-bearing" In Juvenile Butterfly Training

In addition to daily special training,young swimmers also need to complete the increasing learning tasks.Therefore,it is of great significance to effectively take into account academic performance,develop athletes ’ special physical quality and improve the training effect in the training cycle.In sports,the use of auxiliary equipment for special training is a common means of coaches to enhance the special quality of athletes,athletic ability and athletic performance has obvious effect.At present,research has proved that the use of ’ liquid load ’ vest training in track and field,badminton and other projects has obvious effect on improving the special physical quality of athletes,and the related application research in swimming projects needs to be verified.In this paper,the vest of ’ liquid load ’ is innovated and improved,so that it conforms to the characteristics of swimming training,and is applied in adolescent butterfly training,trying to provide new ideas and directions for the development of adolescent swimmers ’ physical quality and athletic performance.In this study,literature,expert interviews,experimental methods,mathematical statistics,18 young swimmers using ’ liquid load ’ training and no load training two models were compared.Through eight weeks of experimental research,two groups of test indicators were collected before and after the experiment.The effect of ’ liquid load ’ vest on young butterfly athletes before and after experimental training was compared and analyzed.The following conclusions :1.The vest of “liquid weight-bearing” is a wearable auxiliary equipment.Its principle is to increase the body load of young swimmers,so that they can adjust the whole body muscle strength to complete the butterfly stroke arm,speed up the frequency of butterfly stroke leg,maintain the body streamline and accelerate the swimming speed,so that the training method is more in line with the way of blocked water in swimming events.The application of " liquid load " vest in butterfly training to develop the special ability of young swimmers is more scientific and targeted.2.After eight weeks of experimental training,the core competence of the two groups of adolescent swimmers has improved to varying degrees,and the experimental group has improved more significantly than the control group.The principle of the application of ‘ liquid weight-bearing ’ vest to improve the core competence is that young swimmers use the liquidity of ‘ liquid weight-bearing ’vest to sandwich the liquid during the butterfly take-off phase.Affected by the load and gravity acceleration,they control the rapid downward pressure of the trunk to improve the core contraction force and balance ability.In the same period of training,the core ability of athletes is better,and the butterfly swimming downward pressure technology of young swimmers is effectively improved.3.After eight weeks of experimental training,the butterfly stroke scores of the two groups of young swimmers have been improved to varying degrees.The improvement in the experimental group is more obvious than that in the control group,indicating that the effect of vest training with liquid weight on improving the performance of athletes is remarkable.In the same training program,the ’ liquid load ’training ensures the stability of athletes ’ technical movements,and effectively solves the problem of insufficient special training time,so as to improve the training effect.
