고교야구선수의 동적균형능력에 따른 하체 관절별 등속성 근력 및 Long- toss의 상관관계 분석

Abstract

Purpose: The purpose of this study is to analyze the relationship between each Isokinetic muscle strength, pitching velocity and long-toss according to the dynamic balance ability level of high school baseball players.<BR> Method: The subjects of this study were 54 high school baseball players in Seoul and Gyeonggi-do Province, chosen as high dynamic balance ability group (27 people) and low dynamic balance ability group (27 people) using Independent t-tests and The Pearson Rank Correlation Coefficient to identify them. The Level of significance was set to α = 0.05.<BR> Results: The results of this study are as follows. All of the left and right muscle strengths except for the lumbar joint strength were similarly higher in the HB group than in the LB group. Pitching velocity and long-toss were also similarly faster and farther in the HB group. Also, the correlation between left and right dynamic balance ability and Isokinetic muscle strength for each lower body joint was significant in all joints except right extensor muscle & left flexor muscle. Long-toss also showed significant correlations in all variables except right pitching velocity.<BR> Conclusion: In summary, Dynamic balance ability is an essential element for effective energy transfer, and high muscle strength strengthening of lower body is considered to increase dynamic balance ability. Thus, if the Proprioception and balance training are applied to increase the muscle strength of the lower body, the pitching velocity will be improved.
