Research On The Training Plan Of Chinese Elite Middle Distance Runners Based On The Comparison Of Energy Supply Characteristics

By collecting the research results of energy supply at home and abroad,this paper makes a comparative study on the energy supply characteristics and training plans of foreign elite athletes,domestic excellent athletes and domestic excellent college athletes in the medium distance running,and finds out the training plan suitable for the middle distance runners of Chinese excellent college students.Based on the characteristics of energy supply and the development of training plan of domestic and foreign excellent middle distance runners and college students,this paper adopts the methods of literature review,expert interview,mathematical statistics,comparative analysis,logical analysis and questionnaire survey.Comparing the energy supply characteristics of excellent middle distance runners at home and abroad and college students,this paper explains the characteristics of middle distance running and makes training plans.By collecting the best scores of 10 foreign excellent middle distance runners,10 Chinese excellent middle distance runners,and 10 Chinese excellent middle distance runners,and comparing the training plans of middle distance runners at home and abroad,this paper calculates the energy supply ratio of the three,finds out the middle difference,and formulates the excellent college students suitable for "combination of learning and training" Training program for middle distance runners.The results show that: the energy supply characteristics of middle distance race have changed,especially the energy supply capacity of lactic acid energy system has improved,which means that the proportion of energy supply of aerobic and anaerobic systems is reduced,which reflects the development trend of middle distance running to anaerobic energy supply.Energy supply and consumption occur at any time.Making plans and guiding training with the characteristics of energy supply law can effectively improve the competitive level.The key factors that determine the performance of middle distance running are the speed ability of athletes and the energy supply capacity of energy supply system.The statistics show that the proportion of aerobic and anaerobic is close to 6:4 in 800 m and 7:3 in 1500 m.Conclusion: 1.The proportion of anaerobic energy supply in sports has been continuously improved,the proportion of anaerobic energy supply of foreign elite athletes is relatively high,and the proportion of aerobic energy supply of domestic excellent athletes and domestic excellent college athletes is still large.As a result,the proportion of anaerobic and aerobic in 800 m of foreign elite athletes is about 56.8:43.2,that of domestic elite athletes is about 55.7:44.3,and that of domestic elite college athletes is about 52.2:47.8.The proportion of anaerobic and aerobic in 1500 m of foreign elite athletes is about 26.18:73.82,while that of domestic elite athletes is about 25.78:74.22.The proportion of anaerobic and aerobic of domestic elite college athletes is about 24.96:73.04,and the anaerobic energy supply of foreign elite athletes is higher than that of domestic athletes.2.In the training plan of domestic and foreign elite athletes,the short-term energy supply stimulation has been carried out for many times.The single training is controlled within 2 points,and the total distance is not more than 2000 meters,which is carried out in the period of anaerobic energy supply capacity.Pay attention to the anaerobic capacity,speed quality enhancement,the formulation of the plan in line with the characteristics of energy supply.Domestic excellent college athletes also make plans in anaerobic condition,but the running time is shorter and the distance is closer,which stimulates the development of anaerobic ability and speed quality under short time and short distance running.3.The present training situation of Chinese elite college students' middle distance runners is characterized by short cycle,less time,difficulty in both training and learning,and many external influencing factors.It is found that the plan of domestic elite college athletes also highlights speed training,but the pertinence is relatively poor,and the speed ability exercise is not prominent enough.
