진동수에 따른 전신진동운동이 하지근 파워 및 점프 수행력에 미치는 영향

Abstract

The purpose of this study was to verify the differences on power generation of lower limb and the optimumfrequency to maximize the power. The subject of this study wacs hosen as 10 able-bodied male students incollege on N university, Chungcheongnam-do, whom there is no me dical history about motor disturbance,paresthesia, nervous system, musculoskeletal system, and listened about the purposes, methods and risks o fstudy, and written the participation agreement. Using random sma pling method, 10 subjects kept an uprigh tposture on the Turbo-Trainer during 5 minutes as the frequency of 8㎐, 26㎐, 40㎐ in order to fit each order,and then practiced 5 times multiple jump on the Accupower for measuring the lower limb power, finally measuredmaximum power, mean power, maximum jump height and mean jump height through the ground reactionforce. Using SPSS 18.0, the data process of this study ccaullated as mean(M) and standard deviation(SD)of all measured value, used one-way repeated measure ANOVA in o rder to verify the significant differencebetween maximum power, mean power, maximum jump height, mean jump height at each frequency. Thesignificant level of hypothesis verification is set-up as α=.05. The results of this study are follows. 1) The maximum power of whole body vibration showed significantdifferences at the 26㎐ only compared with before implementation(p <.01). 2) The mean power of wholebody vibration showed significant differences at the 26㎐ only ocmpared with before implementation(p<.05). 3) The maximum jump height of whole body vibration showed sigfniciant differences at the 26㎐ only comparedwith before implementation(p<.05). 4) The mean jump height of whole body vibration showed significantdifferences at the 26㎐ only compared with before implementation(p<.05). In summary, during whole body vibration according to frequencya ffect to lower limb power at 26㎐, theoptimum frequency except mean jump height has verified at 26㎐ ude to the significant difference has beenappeared at the maximum power, mean power, maximum jump heighet xcept mean jump height. Therefore ,this study is provided to sports scientist, supervisor, coach, trainer and player whom need the enhancement oflower limb power as scientific basic data and will be contributed to their performance enhancement
