다국어 초록 (Multilingual Abstract)

The aims of this study is to find how the weight lifting training effects upon enduring muscular contraction speed.With 65 Sample; 20 general study, 17 physical education major, 10 volley ball player, 10 judo player, 10 weight lifter from Hanyang University student,20-26 years of, age, To measure the speed of arm circumduction in 60 Seconds. With Rotational arm Motion speed Analyzer of each resistant weight; 0g. 300g, 800, 1300g, The results are as follows;1. Arm circumduction speed in 0g resistant weight was; weight lifter 32.9/RPM, Judo 37.8, Volley ball 29.9, physical Education mojor 24.0, General study 20.5,2. Resistant weight 300g speed of Arm Circumduction was; Weight lifter 30.1, Jude 27.9, Volleyball 26.9 physical Education major 24.0 General study, 20.5,3. Resistant weight 809g speed of arm Circumduction was; Weight lifer 29.4, Judo 24.6, Volleyball 23.0, physical Education major 16.6, General study 12.9,4. Resistant weight 1300g speed of arm circumduction was; Weight lifter 18.4, Judo 16.8, Volley ball 14.9, Physical Education mojor 11.6, General Study 8.5.For the above each variable resistant weights Rank order for arm circumduction speed shows weight lifter, Judo, Volley ball, physical Education-major, General study, and also to see that the between fatest of weight lifter and dullest Group of General study was statistically P<0.001 Significant level, Above all it may be conclud that weight lifting training, of which effects great value upon shortening tinge of enduring muscular Contraction speed.
