A Research On The Correlation Between Galop Results And Lower Limbs Coordinate Ability

Coordinate ability of lower limbs is one of the requisite abilities in ballroom dancing possessed by sports dancers,and it is also the foundation and core for ballroom dancers to master various technics and improve sports results.Compared with other four ballroom dances,galop has faster movement and changes of footsteps,with the very technique of instantaneous changes.Therefore,galop is demanding for coordinate ability of lower limbs.Sports training experts agree that coordinate ability is a precondition for developing sports skills;A good coordinate ability helps players to reduce power consumption,improve sports efficiency and master movement skills of high quality,so as to improve the technical level of players.Based on the data collected by the methods of literature review and expert interviews,the evaluation index of lower limb coordination ability of fast-paced dance was optimized by Delphi method.The index of lower limb coordination ability of fast-paced dance was studied experimentally with 10 pairs of excellent dancers from the 21-year-old standard dance group in the 28 th National Sports Dance Championship in 2018.According to the results of expert tests,through the Spearman rank correlation analysis method and SPSS statistical software,the correlation test and comparative analysis of 10 pairs of fast-paced dancers' athletic performance and coordination ability are carried out,so as to achieve the research purpose of discussing the linear correlation between the lower limb coordination ability and athletic performance of fast-paced dancers.The research concludes as follows:1.The article finally screened out 11 coordinate ability assessment index of lower limbs related to galop results by Delphi method,among which the general coordinate ability assessment index of lower limbs includes repetitive side-step,quadrant jump,hop or swing ahead and side crossover step;the special coordinate ability assessment index includes pendulum step,jumping jack hoturn hop in place,rear inclined kick jump,quick chasse to right,quick chasse to left,saute+changement+echappe,Battement tendujete + Battement frappe;2.Correlation test of galop results and coordinate ability is as follows: 3 index including repetitive side-step,quadrant jump and hop or swing ahead,which reflect general coordinate ability,are linear correlative with galop results;5 index including pendulum step,hop in place,jumping jack hoturn,saute + changement + echappe,and quick chasse toright/left,which reflects special coordinate ability are linear correlative with galop results of players.3.In ballroom dance teaching and training,some targeted training against coordinate ability of lower limbs,coordinated with the requirements of special technics,shall be properly added,so as to optimize the training effects.
