碩士 === 臺北市立師範學院 === 國民教育研究所 === 89 === The purpose of this study was to explore the influence of five different body extending-lengths to the five different static Tug of War posture on the effect of horizontal pulling-force for the Wan-Fu elementary school team player. A pulling-force extensormeter and a set of VHS camera served as major equipments for this study .The subjects were 40Tug of War team players of Wan-Fu elementary school （age:12.1 ± 0.46 year;height:156.5±6.0cm;weight:47.9±8.7kg）.After data collection, the SPSS statistic computer software was used for the basic data statistics and the polynomial regression analysis. After data treatment, the results were reached as followings: 1.The horizontal pulling force was increased when the body extending-length was reduced, and the maximal pulling force occurred at 60﹪of body extending-length for the highest and mid-high posture. 2.The horizontal pulling force was increased then backed to the decreased when the body extending-length was reduced, and the maximal pulling force occurred at 80﹪of body extending-length for the middle posture, the mid-low posture and the low posture. 3.The 80﹪ of body extending-length of the middle posture and the mid-low posture were the best appropriate postures for the elementary school team player.
