摘 要
本研究目的在探討拔河實際比賽起始階段不同情境隊形（獲利、僵持、失利）中之預備動作與拔河繩最低點動作的運動學變化及差異，以參加九十七年全國拔河錦標賽高中職男生組560公斤級之十所學校優秀選手為研究對象，受試者平均身高173.47 ± 5.20公分、平均體重68.23 ± 5.04公斤、平均年齡16.99 ± 0.77歲。以兩部高速攝影機(型號JVC-9800U)，頻率120Hz，將所蒐集的影像資料經由Visual Basic 6.0所撰寫的數位化程式進行分析，並計算出不同情境下拔河隊員的各項運動學參數，以SPSS 10.0軟體，採用獨立樣本單因子變異數分析（one-way ANOVA）進行統計考驗，顯著水準訂為α = .05，事後比較採用薛費法（Scheffe’method），得到以下結果：（一）預備動作的僵持隊形與獲利隊形、失利隊形在軀幹與水平的夾角、小腿肢段與水平的夾角、身體重心與水平的夾角達顯著差異（p< .05）。（二）拔河繩最低點動作的獲利隊形與僵持隊形在大腿肢段與水平的夾角達顯著差異；僵持隊形與獲利隊形、失利隊形在握繩高度達顯著差異（p < .05）。所得結論為:（一）預備動作的拔河團隊隊形不同位置握繩高度保持一致性，對一開始的比賽是有利的。（二）拔河繩最低點動作的拔河團隊隊形越低，對比賽的開始有利的。

The indoor tug-of-war team formations kinematic analysis for the start of competition Master’s thesis, June,2008 Graduate student：Liu, Chia-Cheng Advisor：Tsai, Chien-Lu Assistant Advisor：Tu, Jui-Hung Abstract The purpose of this study was to compare the different team formations (win, lose, standoff) variations and differences in the start and the moment when the height of the rope at the lowest. The subjects came from ten high school male elite tuggers. The height, weight, and age were 173.47 ± 5.20cm, 68.23 ± 5.04 kg, 16.99 ± 0.77 years. The main apparatus were two high speed digital video cameras (120Hz). We had designed the digitized program by the Visual Basic software in order to get the kinematics data from the different team formations. A One-way ANOVA and Scheffe’s post-hoc comparisons (α = .05) were used to test the kinematics data by the SPSS 10.0 statistical software. The results were:（1）In the start has a significant difference (p ＜ .05), on the different team formations, including trunk angle, leg segment angle, and cg angle.（2）The moment when the height of the rope at lowest has a significant difference (p ＜ .05), on the losing and standoff team formations, including thigh angle, and there were difference between three team formations on the height of the rope. And the conclusion are:（1）In the start to keep the unity of the rope height is beneficial for a team to win the game.（2）The moment when the height of the rope at the lowest to keep the lower height of the team formation is beneficial for a team to win the game.
