一、參加會議經過

此次參加的會議為第五屆世界生物力學研討會(5th

World Congress of Biomechanics)，承辦 單位為歐洲生物力學學會及慕尼黑應用科學大學(The European Society of Biomechanics, Munich University of Applied Sciences )，開會日期為 2006 年 7 月 29 日至 8 月 4 日，共計七天，地點在 慕尼黑應用科學大學 (Munich University of Applied Sciences )。以下為參加會議的經過描述：

此次世界生物力學研討會於 7 月 29 日開始。此研討會為四年舉辦一次的國際性的生物力 學研討會，涵蓋領域非常廣泛，舉凡與生物力學有關的範圍皆包含在內，此次參與此研討會 的國家多達 30 國、人數超過 3000 人、海報發表 850 篇及口頭發表 2050 篇。由於發表場次及 人數眾多，因此同一時段中有 28 個場地同時進行口題發表，故在如此大型的研討會能得到更 多新的資訊及觀念，使國際間的學術交流更多元化，另外於會場中心有多家廠商擺設最新儀 器產品參與展示，提供與會學者最新的儀器資訊。

會期中計有 4 場 Plenary Lectures，由來自 University Auckland, New Zealand 的 P. Hunter 主講 Challenges in Multi-Scale Modelling。來自 University of Pittsburgh, USA 的 Savio L.-Y-Woo 主講 Biomechanics Research and Sports Medicine’s Future: Meeting the Challenges of Keeping your Knee and Shoulder Healthy。來自 Hospital Vandoeuvre les Nancy, France 的 J. F. Stolz 主講 Regenerative Medicine: From Engineer to Clinical Application。及來自 MIT, Boston, USA 的 Roger Kamm 主講 The Role of Molecular Mechanics in Intracellular Signaling-Mechanisms and Modells。

INTRODUCTION

The competition rules of Taekwondo was modified to prefer the successive kicking

which can get more points since the last official event of the Olympic game. The rule

encourages the number of attacks relative to the intensity of attacks. In previous

studies, the researchers were focus on single kicking technique, not successive

kicking yet (Park,1989; Sung,1987). The successive kick is composed of several

single roundhouse kicks the most frequently used technique in competitions (Fig. 1).

However, the training of successive kicking technique depends on coach experiences

at present, the guidelines are not clear. Therefore, the purpose of this study was to

analyze the differences of kinematics characteristics between single kicking

technique and successive kicking technique through Motion Analysis System.

METHODS

used to collect the kinematics data through tracking the makers automatically, and

then the timing sequence of peak joint velocity for each lower limb were derived

from the time series.

RESULTS AND DISCUSSION

The results were: 1. The sequence of the peak joint velocities for the lower extremity

were hip, knee, and ankle, which were in accord with the kinematics chain of human

exercise which smaller joints move after bigger joints move for both type of kicking

techniques. 2. The successive kick was larger than the single roundhouse kick in the

shoulder-hip-axis projected angle on horizontal plane.

CONCLUSIONS

The results suggest that the successive kicking movement perform more trunk twist

which may contribute to balance the lower extremity round kick motion through the

conservation principle of the angular momentum.
