Research On The Influence Of Sandbag Resistance Training On Children Dancers Special Speed Of Lower Limbs In Latin Dance

With the continuous development of children’s Latin dance,its competitiveness is becoming stronger and stronger.Some of the special qualities of foreign excellent children’s Latin dance players,such as special speed quality,sensitive quality,flexibility quality,are close to the level of adult players.Especially in special speed quality,foreign excellent children’s Latin dance players have reached a higher level.Therefore,in order to improve the competitive level of Chinese children’s Latin dance players,we must pay attention to improving the special quality of children’s Latin dance players,especially the development of special speed quality.The purpose of this paper is to study the influence of sandbag resistance training on children’s Latin Dance Players’ lower limb specific speed quality ability,explore the feasibility of resistance training for children’s Latin Dance Players’ lower limb specific speed quality training,and provide certain theoretical and practical guidance for children’s Latin Dance Players’ lower limb specific speed quality resistance training.Taking the influence of sandbag resistance training on children’s Latin Dance Players’ lower limb specific speed quality as the research object,27 children’s Latin dance students aged 7 to 12 were randomly divided into experimental group,control group and reference group The traditional lower limb special speed training program and special technology consolidation training program of children’s Latin dance were carried out in three experimental groups for 12 weeks.The changes of experimental test index test data within and between groups before and after 12 weeks of experimental intervention were analyzed and compared.Combined with literature,the influence of sandbag resistance training on children’s lower limb special speed quality of Latin dance players was analyzed.The results are as follows :1.The test scores of the four test indexes in the experimental group and the control group after the experimental intervention were improved compared with those before the experimental intervention,and there were significant differences in the test scores of all test indexes before and after the experimental intervention;In the control group,the test scores of the four test indexes after the experimental intervention were improved compared with those before the experimental intervention,there were significant differences in the test scores of three test indexes before and after the experimental intervention,and there was no significant difference in the test scores of one test index before and after the experimental intervention.2.After the experimental intervention,the growth rate of the test scores of the four test indicators in the three test groups was higher than that in the control group and the reference group,and the growth rate of the test scores of the four test indicators in the experimental group was significantly different from that in the control group and the reference group.Through the analysis of the experimental results and literature,the following conclusions are drawn:1.Lower limb sandbag resistance specific speed quality training can significantly improve the test results of 7-12-year-old children’s Latin Dance Players’ fastest lower limb specific movement speed and lower limb specific speed endurance test index,and the overall training effect of lower limb specific speed quality is significant.2.Traditional lower limb specific speed quality training can effectively improve the test results of the fastest lower limb specific speed test index of 7 to 12-year-old children’s Latin dance players,which has a certain training effect on their lower limb specific speed quality,but the improvement of their lower limb specific speed endurance test index is not obvious,and there is no significant training effect on their lower limb specific speed endurance.3.Simple technical training can improve children’s Latin dance lower limb special speed test results to a certain extent,but the improvement is small,and has no significant training effect on their lower limb special speed quality.4.The special speed training of children’s Latin dance lower limb sandbag resistance,the special speed training of traditional children’s Latin dance players and the simple technical training have improved the special speed quality of children’s Latin dance lower limb,Among them,sandbags resistance training has the most significant effect on the test results of lower limb specific speed test index than the traditional lower limb specific speed training and simple technical training of children’s Latin dance.
