Research On The Effect Of Eccentric Training On The Balance Of Muscle Strength Of The Knee Flexors And Extensors Of Latin Dancers

Research purposes: it is made centrifugal training a Latin dance contestant knee flexor muscle balance an effective training method,this paper adopted by way of centrifugal training method for the functional training,the method in 2013 has become all kinds of sports training methods,such as basketball special technology action of sprinters leg knee joint strength training,resistance training after knee joint and muscle strength training and so on,are mainly strengthen muscles leg knee joint flexion and extension,including the quadriceps and hamstring muscle group,to enhance the stability of the knee joint of lower limbs.Centrifugal training effect on human body generates a muscle pull,slower at the same time,and constantly in the process of slow training to stimulate muscle tension,prompting leg knee joint muscle fibers became thicker,enhance the muscle flexor resistance ability,eventually to achieve the balance of knee flexor muscle and joint stability.Research methods: this paper USES the methods of literature,expert interview,experiment and mathematical statistics.The experiment mainly from the chengdu sports institute 2015 level of Latin dance special class of 24 Latin dance contestant in this experiment,including 12 Latin dance contestant as experimental group centrifugal training,another 12 Latin dance player as control group routine Latin dance class of regular strength training.The centrifugal training method adopted in this experiment is: kneeling centrifugal training method;Resistance training method;And the static squat training method was used to train 12 subjects on knee flexor muscle strength for 8 weeks.After the training,the data obtained from the experiment are analyzed and discussed scientifically.The results show that as a functional rehabilitation training,centrifugal training has a certain effect on the strength balance of Latin dancers’ knee flexion and extensor muscles.For this,I also USES expert interview method,listened to professor an-li wang in chengdu sports college academic BBS,and specially consulted the professional knowledge,do a solid foundation for this experiment.Finally,this paper makes a reasonable analysis of data through SPSS17.0 mathematical statistics method,completes the experiment and obtains the results.The result: 12 subjects in 8 weeks of knee joint centrifugal training results summary,first from the perspective of a strength detection system such as operation interface,12 Latin dance after the centrifugal training subjects in lower limb knee flexor muscle balance ability stronger,the knee joint obviously adapted to the centrifugal control stage of resistance;Secondly in knee joint peak torque ratio results show that the peak torque ratio has a significant increase,also suggests that Latin dance contestant leg knee joint in the case of static flexor muscle balance has very big effect.At the same time,Y-balance comprehensive value was used to test the balance and stability of the knee joints of Latin dancers under dynamic conditions.Results showed that the centrifugal training after the Latin dance contestant in dynamic cases lower limb knee joint is a breakthrough,the balance shows the lower limb muscle group got knee flexion and extension of effective training.Conclusions: Centrifugal training is a targeted training method and is also the most common functional training method,centrifugal training on Latin dance contestant knee flexor muscle balance has good training effect,the use of Y-balance test instrument for the balance ability before and after the training the comprehensive value of monitoring data,after 8 weeks of training on the subjects,not only improves their muscle group of muscle tension and enhances the dynamic balance between knee flexor muscle,so that you can rise to the balanced development of muscles,also avoid the knee joint injury concerns,Therefore,centrifugal training plays an irreplaceable role in Latin dancers’ knee flexor muscle balance.Latin dancers in the lower limbs of the knee joint centrifugal training effect is significant,to a large extent to enhance the knee joint flexor muscle strength and has reached a balanced and stable effect.However,we suggest that in Latin dance special class shall be reasonable use of centrifugal training,must be warming up before the class and in the lower limbs around the knee joint muscle group after fully stretch in centrifugal training,to ensure that the centrifugal training to the Latin dance contestant muscle fibers maximum stimulation;When performing centrifugal training,professional teachers should provide guidance and assistance.Meanwhile,subjects should maintain high attention to ensure the strength and effect of Latin dancers’ flexor extensor muscle training.
