| Objective: Considering the effect of unstable training on the "Tour à la seconde",with "Tour à la seconde" action technology practice for the mother,combined with the stable training application and mechanism,the stable training with special technology,design the stable training content,the 24 subjects "Tourà la seconde" experiment,to explore the stable training of "Tour à la seconde" action quality effect and concluded that for such turn difficulty action to provide scientific novel training scheme,broaden the use of unstable training areas,To provide a reference for the application of unstable training in other sports movements or events.Methods: This paper uses 5 research methods,(1)literature data method:collect relevant data.(2)Expert interview method: understand the relevant research status,research content,quality evaluation indicators and test methods of "Tour à la seconde" action.(3)Image analysis method: use kinovea motion analysis software for motion analysis.In the experiment,the "C" bar " was taken from multiple angles,and the data was recorded and analyzed.(4)Experimental method: the college cheerleading community 24 members randomly divided into2 groups,experimental group using the stable training program six content training,control group using conventional training program four content training,two groups of training time and the same scale,experiment a total of 8 weeks,training for 30 minutes each time,a total of 16 times.(5)Mathematical statistical method: In this paper,the quality of "Tour à la seconde" requires 5 indicators(the number of laps,expert score,Angle of ankle and ground,the Angle of swinging leg and leg,the Angle of axis deviation during rotation);three kinds of index test methods,namely,recording the number of "Tour à la seconde"movement,organizing experts to score,kinovea motion analysis software;and statistical analysis of the index test data during the experiment.Results: An experimental study on the quality of the C bar completed by unstable training.(1)For the circle count index of "Tour à la seconde",there was a very significant difference between the experimental group(P <0.01);there was a significant difference between the two groups after the experiment(P <0.05).(2)For the expert scoring index of "Tour à la seconde",the comparison between groups after the experiment was significant(P <0.05);and significant(P <0.05).(3)The "Tour à la seconde" support Angle between the ankle and the ground,and the comparison within the experimental group was significantly different(P <0.05);the comparison between the groups after the experiment was not significant(P> 0.05).(4)The Angle index of the swing leg and the supporting leg of the "Tour àla seconde" showed no significant difference between the experimental group(P> 0.05),and no significant difference between the groups after the experiment(P> 0.05).(5)In the action of "Tour à la seconde",the comparison within the experimental group was significant(P <0.05);after the experiment(P <0.05).Conclusion: After the experimental study of the quality of "Tour à la seconde",the following conclusions are drawn.(1)The stability training has a significant positive effect on the completion quality of "Tour à la seconde";after 8 weeks of training experiment,the angle between the ankle and the ground of the supporting leg and the ground.(2)The unstable training program adopted in this paper can make the subjects increase the number of turns,improve the turn efficiency,and help the subjects to improve the completion quality of the "Tour à la seconde" action.(3)After 8 weeks of training experiment,it is found that the unstable training program can keep the subjects in a stable and controllable state during the rotation,improve the muscle strength and balance ability,and thus improve the completion quality of the "Tour à la seconde" movement.(4)After 8 weeks of training experiment,it is found that the unstable training scheme should be designed with the advanced medium difficulty unstable training,and the unstable training of the corresponding part should be set according to the force mode of the technical action.Suggestion: The following suggestions are obtained from the experimental study of the quality effect on the completion of "Tour à la seconde" through unstable training.(1)Unstable training methods can be widely used in the "Tour à la seconde" and other single foot rotation difficult training,to provide scientific and efficient training plan for coaches and improve the training efficiency for athletes.(2)It is suggested to pay attention to the advanced setting of the training amount and adjust the training content in time.(3)It is suggested that the unstable training content of the comprehensive ability of swinging leg and hip joint should be added to the unstable training program of "Tour à la seconde",so as to improve the significance of the swinging leg training effect.(4)It is suggested that relevant scholars can pay more attention to and pay more attention to such research,improve the difficulty level of single-foot rotation in China,and provide reference significance for relevant coaches and athletes in China. |
