摘 要
在小學生日常玩耍或體育課的課程內容中隨處可見包含著地型態的動作,以往國內外的相關研究大多集中在成年人,欠缺小學生的資料,為此,本研究分析桃園縣新勢國小三、四、五、六年級學童於相同高度(40公分)赤腳著地時的運動學和動力學特徵,並以單因子變異數方法加以分析(a=.05),達顯著差異時再以薛費法進行事後比較。結果發現:1.著地瞬間、重心垂直速度為零時下肢關節角度中,只有膝關節有顯著差異,緩衝時間則無差異;2.在角位移、到達地面垂直反作用力第一峰值和第二峰值的時間、第一峰值到第二峰值時間間距方面,會隨著年級增加而增加;3.在著地期間下肢各關節的最大角速度和產生時間,踝、髖關節有差異存在,地面垂直反作用力的第一峰值、第二峰值、50毫秒內的被動衝量及到達第一峰值時的衝量隨著年級增加而減少,且達顯著差異,第二峰值時的衝量則沒有顯著差異。因此建議在國小體育課程中多教導學生主動利用膝、髖關節屈曲及延長緩衝時間來減低著地時所產生的巨大撞擊力量,避免可能造成的傷害。
Abstract
Among all of primary school students activities, landing movement is commonly seen during daily playing or sports classes. The present domestic and foreign related researches focus on analysis adult athletes. This research thus focuses on primary school students of Hsin-Shih Primary school, Taoyuan county and compares the kinematics and dynamics characteristic differences of third, fourth, fifth, and sixth-graded students’ jumping to the same height (40cm) by bare-foot. The information reference of biomechanics of this research are analyzed by one-way ANOVA method ( α =. 05). When the differences reach a certain level, the differences will be compared by Scheffe methodology. The analysis indicates that : (1) During an instant vertical landing with falling speed of zero, among the angels of lower body’s joints, only the knee joints pose an obvious difference but there is no difference among the elapse times. (2) The angular displacement, time to the first peak force(PK1) and second peak force(PK2)of ground reaction force of vertical landing will increase in proportion to the increase of age. (3) Except the knee joint, during the elapse of landing, the biggest angel velocity and exact timing are obviously difference. The PK1, PK2 and the passive impulse in less than 50 mini-seconds will tend to decline in proportion to the increase of age. Finally, the difference of reaching the first peak force pulse will decrease among students of all grades . For the measurement of the second peak force of impulse, all students are nearly the same. Thus, it is advised that primary school students be taught to exploit the bending of knee and hip joints and expanding elapse times so as to reduce the huge impact of landing repercussion and also to avoid possible relating injuries.
