The Experimental Research On Aerobic Capacity Training Of Elite 400-meter Race Athlete In Zhejiang Province

By means of literature, experimentation, statistics and logical analysis, the research on the elite 400-meter run and 400m Hurdles athletes in Zhejiang province, to explore the 400-meter athletes in the development of aerobic capacity of the scientific training, analysis of the Lactic acid index before and after the experiments, to determine training intensity, the subjects AT4 corresponding running speed and other content, verify that aerobic exercise training on the ability of subjects. to further control 400-meter race training aerobic capacity provide the basis for the law, and practice for the majority of the training of coaches to provide reference, so as to promote the 400-meter runners training for scientific development.The results showed:(1)400-meter race aerobic capacity of training content in the training system plays an important role. (2) the use of blood lactic acid can be determined for the 400-meter runners training intensity, select training methods, evaluation of training results provide an important basis for monitoring. (3) 400 m Run Elite athletes training with the development of anaerobic threshold intensity aerobic capacity effect is obvious. (4) using lactate threshold for 10 classes for 8 weeks of aerobic endurance training, subjects under the same running speed significantly decreased lactate threshold, aerobic capacity decline in the value of strong lactic acid faster than aerobic metabolism poor are much faster. (5) 400-meter runners to improve aerobic capacity can support and complement the overall anaerobic lactic acid metabolism, so as to achieve the purpose of improving anaerobic capacity.Suggestions: (1) elite 400-meter runners with anaerobic threshold intensity monitoring aerobic capacity training, athletes should be paid attention to the stage of training at any time, test data analysis and evaluation. (2) 400-meter runners in the development of aerobic capacity training, to monitor by the use of blood lactic acid, must take full account of individual characteristics and special features. (3) continue to deepen the 400-meter athletes′aerobic capacity training practice of exploration, to the formation of individual character and style of training.
