An Experimental Research On The Influence Of Sandbag Resistance Training On The Lower Limb Movement Strength Of Children’s Latin Dance

As can be seen from the results of various Latin dance competitions in recent years,the special movement speed plays an increasingly important role in the whole competition,and the lower limb movement speed,as an important part of the special movement speed,directly affects the competition level of Latin dancers.At present,the Latin dance lower limb movement speed training is mostly use the unarmed training methods,teachers’ technical movements,the interpretation of the student to carry on the simulation exercises,the conventional training method is relatively single,boring when the students master the basic steps of behavioral essentials,want to further enhance the tripping speed of the lower limbs of the Latin dance,auxiliary devices that can be used.After reviewing relevant literature,it is found that there are few researches on the influence of sandbag resistance on children’s Latin dance training in China,especially on the influence of lower limb movement speed training of children’ s Latin dance.Therefore,the influence of sandbag resistance training on Latin dance students’ lower limb movement speed was studied,so as to discuss the specific influence and effect of sandbag resistance training.Latin dance is a kind of sports project dominated by skills and difficult to show beauty.It is characterized by high appreciation while showing the soft beauty of dancers and the diversity of dance forms.Sandbag resistance training is an effective training method to improve speed.By comparing sandbag resistance training and no instrument training,the lower limb movement speed training method which accords with Latin dance special movement characteristics is explored.Using the method of documentary,expert interview,mathematical statistics method,questionnaire survey method,experimental method and other research methods,with sandbags resistance training as the breakthrough point,40 students of Maoming electric dance training organizations mechanism for 1 2 weeks of teaching experiment,using grouping random sampling method,divided into the experimental group and the control group,by collecting data from two groups before and after the experiment.The lower limb movement speed indexes of the two groups were evaluated before and after the experiment,and the influence of sandbag resistance training on the lower limb movement speed of children Latin dance was analyzed.Through the research,it is concluded that:1.After 12 weeks of sandbag resistance training,the lower limb motor speed index of the experimental group was significantly improved compared with the control group,and showed significant differences before and after the experiment（P<0.05）.2.Sandbag resistance training plays an effective auxiliary role in Latin dance lower limb movement speed training.Compared with conventional Latin dance lower limb movement speed training,this auxiliary training method can improve the explosive force and control of the legs of Latin dancers more effectively.3.In the same training time,the experimental group of Latin dancers in strength and endurance quality are better than the control group.Sandbag resistance training can improve the lower limb movement speed greatly,and can effectively develop the lower limb explosive power level of Latin dancers.4.In Latin dance leg closing speed,through the comparative experiment found that the experimental group of sandbag resistance training,its leg closing speed is significantly improved than before.In the control group,there was no significant change in leg closing speed.It shows that sandbag resistance training can effectively improve the leg closing speed of children Latin dance.It is suggested to grasp the sensitive period of lower limb speed development of children Latin dancers,design training plans according to the special characteristics of Latin dance,and carry out sandbag resistance training,so as to lay a good foundation for future special development.
