The Kinesiology Research About The Influencing Of Core Strength Training To The Spin Turn Skills Of Latin Dance Sporters

Objective: Using the kinematics analysis about the flat spin skill movements before and aftercore strength training of the Latin dance sporters to conclude the influences of core strengthtrainings to the swing skills of Latin dance sporters.Methods: This study analyses the experimental group’s Latin dance sporters which carryout the trainings of core strength, uses two normal speed cameras to record the swing skillsbefore and after trainings of core strength, and uses APAS analytical software to analyse thedatas before and after experiments.Results:(1) After the core strength trainings, the sporters have the significant differences on movementtime of flat spin skill. After core strength trainings, the sporters make the action speed muchfaster than that before the core strength trainings.(2) Keeping the body Angle vertical guarantee flat spin finished with high quality. After Corestrength training, the abilities of core muscles of the whole spine, hip, lower limb joints arestrengthened.(3)Hip is the core part of the body, the angle changes of hip can reflect the effects ofcore strength trainings, and meanwhile it is the decisive factor to finish the skills with high quality. After core strength trainings, the hip joint angle always stay within thescope to finish the skills favorably.(4) Knee joint is the lower limb joint of the body, the angle changes of it not only can reflect theeffects of core strength trainings, but also reflect stabilization level of lower limbs. After corestrength trainings, the lower limb support ability of the sporters are strengthened.(5) Speed indicator is one of the important contents of kinesiology analysis, and is the reflectionof skill factors. After core strength trainings, the speeds of hip, knee are much faster than thatbefore the trainings.Conclusions:Using the research method of kinesiology, analysing the datas of swing skillsof Latin dance before and after the core strength trainings, this thesis find that core strengthtrainings have the positive influences on the flat spin skill of Latin dance sporters.Suggestion:(1)After core strength trainings, the flat spin skills of Latin dance sporters obtain the good effects. This thesis suggested that the Sportsdance lovers, coaches should try to apply it in the dailytrainings.(2)The core strength trainings should become the important training content of Latin dancesporters’ physical trainings. However, the core strength training methods is in the low leverWhen it is combined with the aspects about the project’s special strength training and flexibilityat present. The core strength trainings still lack of necessary methodology guidance.(3)For the Latin dance sporters, they should not only strengthen the stability of the core region,but also should strengthen the stabilities of the ankle joint, shoulder joint and stance.Only to takethe stable ability trainings of whole body, the sporters can adapt to the project movementcharacteristics and enhance the skill level of Latin dance.
