目的：本研究欲探討兒童與青少年高爾夫選手擊球時下肢動力學和桿頭速度差異。方法：14位男性兒童與14位的男性青少年，共28位，並分成兒童組與青少年組兩組。利用測力板與揮桿表現檢測工具與儀器進行量測。以獨立樣本t－test比較兒童組與青少年組桿頭速度、左右腳地面垂直反作用力之差異。結果：青少年組桿頭速度較兒童組快且達顯著差異。在地面垂直反作用力部分，上桿期右腳（後腳）與下桿加速期左腳（前腳）都是兒童組的垂直地面反作用力大於青少年組，其他期別皆無顯著差異。結論：在桿頭速度，兒童組桿頭速度接近於中老年組，青少年接近於非優秀（中差點）選手，這可提供教練在訓練上，對於桿頭速度給予適當的要求，避免兒童與青少年選手過於追求與成人優秀選手相同的桿頭速度而受傷。在地面垂直反作用力，兒童組因為身體發育趨於緩慢，技術動作會較穩定，教練反而可以要求在重心轉移能力可以接近成人優秀成人選手。青少年組因為身高快速發展，肌肉骨骼並未跟上身高的速度，在重心轉移能力要求，可以讓他們接近於非優秀成人選手，才是適合他們這個階段的技術動作。

Purpose: This study was to investigator the difference of the lower limb kinetics in children and adolescent golfers during the swing. Methods: 28 male golfers participated in this study were divided in 14 children golfers and 14 adolescent golfers. The measure with force plate and swing performance tools and instruments. The t-test compare with the difference of children and adolescent in club head speed and vertical ground reaction force. Results: In club head speed, the adolescent groups were significant faster than the children's groups. In vertical ground reaction force, the children's groups were significant bigger than the adolescent groups in left foot (front foot) at backswing phase and right foot (back foot) at acceleration phase. Conclusions: In club head speed, because of the difference in body development. the club head speed of the children's group is close to that of the middle-aged group. The adolescent groups are close to the non-elite (mid-handicap) players. This research finds that coaches can be trained to give appropriate requirements for the club head speed. Avoid children and adolescent golfers who are too wounded to pursue the same club head speed as elite adult players. In vertical ground reaction force, the children's group tends to be slower due to physical development, and the technical movements will be more stable. Coaches can instead request that the ability to weight shift can be close to elite adult players. Because the height of the adolescent's group is rapidly developing, the musculoskeletal bones have not kept up with the height of the body. The ability of the weight shifting can make them close to the non-elite adult players, which is the technical action suitable for them at this stage.
