Experimental Study On The Effect Of Special Physical Fitness Intervention On Sprint Performance Of Students Majoring In Sports Training

Physical fitness is the basis of all human activities and objective behavior,and is the primary carrier for people to achieve the goal of leisure fitness and high level competitive sports.The experimental study shows that the proper use of special physical fitness in the sports training can enhance the quality of special sports and improve the performance of sports.Scientific physical training can strengthen the ability to exercise,with other means can not be replaced.Special physical training as a means of intervention,the establishment of special athletes physical understanding,theoretical knowledge of special technical improvement,the improvement of sports performance,learning motivation and self-confidence training can play an important role.In physical training,reasonable use of special physical intervention,to improve the performance and quality of teaching has a positive significance.In this paper,the use of literature,interviews,mathematical statistics and experimental methods to study.Taking the 20 students of sports training in Hunan Normal University as the research object.Of which 10 students conducted a special physical intervention on the impact of sprint performance experimental training.The main purpose is to study the effect of special physical intervention on the performance of sprint,and summarize the contents,methods and methods of physical training of modern sprint project,and hope that the special knowledge and practical ability of the sprinter after training are more comprehensive Ascension.For the future engaged in physical education and training work to lay a solid foundation.Through the sprint athletes 3 months of special physical intervention training,the experimental group and the control group before and after the experiment the speed of quality,endurance quality and strength of quality comparison,the results are as follows:1.through the special physical quality of speed significantly improve the athletes intervention,for the performance of the 30 meters,60 meters high achievement is obviously higher than that before the experiment(P<0.05,P<0.01),and the special physical intervention eftect on the quality of speed of sprint athletes is better than that of the conventional physical training.2.running speed through the speed endurance athletes special physical intervention and maintain the way ability significantly improved performance for 150 meters,300 meters result has significantly improved(P<0.01),and the special physical intervention effect on endurance of sprint athletes is better than that of the conventional physical training.3.by special physicalintervention athletes strength quality significantly improved performance for out,standing long jump,squat performance has significantly improved(P<0.05),and the special physical intervention effect on power quality is better than that of the conventional physical training of sprinters.4.experiments found that the general pattern of physical training and special physical intervention training mode of two groups of athletes sprint performance has improved,but the students of sprint exercise training intervention through special physical improvement has significant effect.5.Low load training large,final result is fatigue and nervous system function decline,so that athletes are trained in a lot of time in the case of runaway and low load,low intensity training,not required to raise our project special function and special ability.The lack of high strength or high strength continuous training in peacetime training,nervous and muscular systems are unable to adapt to match this continuous high intensity stimulation,it can be said,this is also one of the long-term effects of low intensity caused by heavy load training.Some suggestions for improving the performance of sprint are put forward:1.special physical fitness intervention has significant influence on sprint performance of sports training majors.It is suggested to try and use in the training of other track and field sports training or other sports events.2.the development of maximum speed,the use of short distance running,the intensity of control between 80%-90%,do not take maximum intensity training.Strength calculation of load motion can be calculated,calculation formula is:n(heart rate training intensity training heart rate heart rate(maximum heart rate)/-100%]*hrrest).3.in the development of speed endurance training,the distance has to change,don't run a distance often,each of the different distance for a short time rest continuous training,strength control in about 60%-90%,to ensure the correct technical movement training.4.special physical intervention is based on the full understanding of the characteristics of the sprint,the special physical intervention process suggested to arrange special physical intervention should be considered comprehensively,and arranged to have sustainable and scientific.5.the training process should not be used too much of the decomposition and local training means to the development of athlete's special ability,and should use special training method to complete;to give full play to the organ and system is closely related with the special potential.6.general physical training is the foundation of special physical training,recommend the use of a variety of general physical training contents and means of training in the future,to make up for lack of special training,to guide the training project according to the characteristics of energy supply.7.in special strength training,combined training should be adopted to avoid excessive training.A large number of long-term low intensity training is likely to cause fatigue,especially fatigue and fatigue of the nervous system,decrease the nervous system and the body will cause the entire quality of training,the training load fluctuation cannot be too large,to maintain system stability and a certain.
