Study on the Influence of Core Stability Training on the Front Smash action of sitting Volleyball

Oral Presentation

Abstract

^{The disabled are an important part of the country and society, because they have certain particularity, so as to do a good job in the protection and services for the disabled, so that the majority of the disabled group effectively enjoy social care, which is the outcome of national development is also an important symbol of social civilization and progress.  Sitting volleyball movement originated in the Netherlands in 1956, is to meet the needs of the disabled community fitness and to participate in volleyball and founded, sitting volleyball team of China in recent years has made great achievement in the international competition, but influenced by multiple factors, with the development of the project, the team scores decline, public participation decline, the lack of related research issues highlighted, for this,  It is worth studying in related fields.  In recent years, core stability training has become an important part of competitive sports training, and has achieved fruitful results in competitive sports.  The research on core stability training is mainly focused on able-bodied sports, while the research on sports and skills training for the disabled is less.  This study uses the method of literature, expert interview, experimental method, mathematical statistics and other methods to study the combination of core stability training and volleyball frontal spike technology, to explore the impact of core stability training on volleyball frontal spike aerial action.  In the experiment, 20 Men's provincial team sitting volleyball players were selected as experimental objects, and they were divided into experimental group and control group, for 12 weeks of training, the experimental group for core stability training, the control group for routine training.  After 12 weeks of experiment, the results were as follows: 1. The core stability and core explosive power of experimental group were significantly enhanced (P<0.05), while the core stability and core explosive power of control group were not significantly enhanced (P>0.05).  2. In the experimental group, the increase of core stability and core explosive force changed the joint Angle when hitting, and the angular displacement of hip joint, shoulder Angle and trunk Angle significantly increased compared with before (P<0.05), and the swing speed significantly increased (P<0.05);  In the control group, there were no significant changes in hip joint Angle, shoulder Angle and trunk Angle (P>0.05), and no significant changes in arm swing speed (P>0.05).  3. In the experimental group, at the moment of hitting, the speed of shoulder, elbow and wrist of hitting arm increased by nearly multiple, indicating that the transmission efficiency of force from the core to the extremity was significantly improved;  In the control group, the speed of the shoulder, elbow and wrist of the hitting arm did not increase by nearly multiple at the moment of hitting, indicating that the transmission efficiency of the force from the core to the extremity was not significantly improved.  Conclusion: In the sitting volleyball training, the core stability can improve the athletes' spiking action and enhance the spiking effect.  Suggestions: 1. The time of the study is short. If the experiment is carried out for a long time, the results will be more convincing and have greater reference value.  2. This study is only a preliminary attempt for the core stability training method of sitting volleyball players. In the later stage, athletes of different ages, genders and training years can be studied to provide a better reference for sports teams.  3. Both core stability training and traditional strength training have their own advantages and disadvantages. They should use their advantages to jointly serve special strength training and selectively conduct core stability training according to the characteristics of the project.}
