武術長拳套路要求有效掌控 1 分 20 秒的演練時間，既不使演練時間太短，產生 「以快遮醜」的現象；也不使演練時間太長，而影響動作節奏與風格的表現。本研究以武術 長拳競賽套路每小節的演練時間為白色訊息，得分為灰色訊息，透過灰色訊息關聯度分析方 法，找尋系統中各子系統之間的關係，目的是了解完成武術長拳套路各小節動作的時間與得 分的關聯順序，以進一步作為了解套路「精神節奏風格」特徵的探討指標。 本文分析 85、 86 年度區運武術競賽男女長拳項目， 五位評分裁判員分數的一致性，以肯德爾和諧係數考 驗，結果均達顯著水準（ P<.01 ）。 再將系統的各項訊息通過灰色訊息關聯度分析模式計 算。結果發現：武術長拳套路各小節動作結構與布局的變化愈大，其時間分配對於分數的影 響也越大。 由於結構與布局的變化豐富，第 8 小節對於分數的影響就較其他小節的影響大 。而第 1 小節、第 2 小節與第 4 小節的時間分配，由於動作路線短、幅度小， 在動作節 奏的展現也就沒有優於其他小節的趨勢。　

　　　　　The design of sports equipment is one of the major factors affecting the sport performance. Tennis and baseball are typical sports which equipment plays an important role. The material, shape, size, inertia, string tension and vibration characteristics of equipment will affect the performance. The vibration of equipment is caused by the impact between the ball and striking equipment. The potential energy is stored by the equipment after the impact, then return it to ball as kinetic energy. Only part of the energy can be transferred to ball's kinetic energy in this impact process, the rest of energy will cause the vibration of the ball and equipment. The vibration of ball will vanish by the air resistance when the ball fly in the air. The vibration of equipmentis absorbed by human hand to produce the vibration load which will cause human body fatigue even injury. Therefore, the vibration characteristics of sport equipment should be thoroughly studied in order to design a optimal equipment. This study proposed the finite element method, a computer simulation method widely applied in other fields to do the modal analysis of sport equipment. Three-dimensional finite element models were developed using ANSYS according to the geometry and material properties of a typical mid-size graphite tennis racket and baseball bat. The first, second and third mode shape as well as the first, second and third natural frequencies were determined using FEM approach. The rest of mode shapes can be ignored due to the low energy of high frequency and low amplitude.
