Research of Practical Training Method of Intermittent Exercise on Improving High Power Endurance Ability during Sports Activities

本研究旨在探讨间歇运动的运动生理特性及训练效果的特异性，并利用视频分析中的二维DLT方法，探索足球、橄榄球、长曲棍球、手球等运动项目在野外进行的实用间歇运动训练方法。研究结果如下：1.间歇运动中的高功率耐力能力与运动员有氧能力和间歇运动后心率恢复呈高度正相关。提示运动后心率恢复对有氧能力和间歇运动能力的评价都是有效的。2.间歇运动训练是提高高功率耐力能力的最有效方法。采用二维DLT方法对曲棍球比赛中跑速的变化进行分析，得出两组运动员在长时间间歇运动测试中的总功率输出无显著差异。4.足球运动员进攻时的快速跑动以对角线跑动和拉开运动为特征。5.从场上、场下不同打法的次数和频率出发，开发了实用的场上间歇运动。间歇运动时的HR、RPE、血乳酸与自行车间歇运动时相似。6.建议将手球运动模拟为间歇运动，包括8组/min的IS内无氧运动、2s的有氧运动和5s的步行或站立运动。

The purpose of this study was to examine the exercise-physiological characteristics of intermittent exercise and the specificity of the training effects, and to develop the practical intermittent exercise training method performed in field on sports activities such as soccer, rugby, lacrosse, and handball using the two dimensional DLT method of video analysis. Results obtained were as follows:1.High power endurance ability during the intermittent exercise showed the high positive correlations with aerobic capacity of players and heart rate recovery from the intermittent exercise. These results suggested that heart rate recovery from exercise was effective for estimating not only the aeobic ability but also the intermittent exercise ability.2.Intermittent exercise training was the most effective method for improving the high power endurance ability, as compared with weight training and endurance training.3.There was no significant difference in total power output during the prolonged intermittent exercise test developed from analysis of changes in running speed during lacrosse game using the two dimensional DLT method between two groups characterized with aerobic or anaerobic abilities.4.Movements of soccer FW players on the offensive were characterized by Diagonal-run and Pull-away patterns within fast running.5.The practical intermittent exercise performed on field was developed from viewpoints of on- and off-play times and frequencies of various play-modes. This intermittent exercise showed the similar values in HR, RPE, and blood lactate acid during the exercise to the values at the intermittent exercise performed with bicycle.6.Handball game was suggested to be simulated as the intermittent exercise, consisted of 8 sets/min of anaerobic exercise within Is, aerobic exercise of 2s, and walking or standing of 5s each.
