INTRODUCTION

Golf是既需要距离也需要准确的运动.距离来自于更大的移动,而精确则需要更大的稳定和较小的移动.在移动与稳定的矛盾中,不同技术水平的球手的解决方法也不同.本研究旨在揭示高手和一般球手如何控制挥杆中的平衡.

METHODS

高手 (AdP)是男性职业球手有过比赛经验.一般球手 (ImP)是男性业余球手,没有比赛经验. 都是右手,使用六铁击球.有些击球是双脚站在便携式Kistler force plate (40x60 cm), 有些是单脚站在压力垫上,另一只在齐平的平台上. 压力数据使用250 Hz采样,由Bioware software处理并转换为体重的单位body weight (BW). Mediolateral (M-L身左身右或是靠近/远离目标) and anteroposterior (A-P身前身后) center of pressure (CoP)用来描述稳定性. 类似的, M-L and A-P 力用于描述移动性.

The front of each subject was videotaped at 60 Hz, and a representative shot

was analyzed to obtain information about balance in the M-L plane. Segmental

end points as they appeared in the M-L plane were digitized and filtered with the

optimal Butterworth procedure of the Peak5 software.标准身体部分的参数用来获得M-L的位置和身体重力线的移动速度line of gravity (LoG). 站位时候与压力垫左右最远的接触点计算出支撑基础参数Base of support (BoS).
