不同落地距離對著地錯誤動作評分測驗之影響-以大專棒球運動員為樣本

Effect of difference landing distance on landing error scoring system score in college baseball player

目的：本研究目的為比較不同落地距離對著地錯誤動作評分測驗分數之影響。方法：本研究以 16 名大專棒球男性運動員為受試者 (年齡：19.37 ± 0.88 歲、身高：175.67 ± 6.14 公分、體重：70.51 ± 8.67 公斤、球齡：7.96 ± 2.46 年)。所有受試者重複量測進行 40 % 身高落地距離、50 % 身高落地距離、60 % 身高落地距離的著地錯誤動作評分測驗 (landing error scoring system, LESS) 測驗。結果：結果發現 40 % 身高落地距離 (5.47 ± 1.3)、50 % 身高落地距離 (5.38 ± 0.97)、60 % 身高落地距離 (5.37 ±1.1) 在 LESS 分數上皆沒有顯著差異 (p <.05)。結論：本研究結論為大專棒球男性運動員進行 LESS 測試時，使用 40 % 身高落地距離、50 % 身高落地距離、60 % 身高落地距離獲得的 LESS 分數和風險分類皆會相似。建議未來教練在測試 LESS 時，可以設置 40 % ~ 60 % 的落地距離，減少測試過程的困難度。

 

Purpose: This study aimed to examine the effects of different landing distances on the landing-error scoring system (LESS). Methods: We enrolled 16 college-going baseball players as participants (age: 19.37 ± 0.88 years, body height: 175.67 ± 6.14 cm, body weight: 70.51 ± 8.67 kg, player’s baseball age: 7.96 ± 2.46 years). All participants performed maneuvers with landing distances of 40 %, 50 %, and 60% of an individual’s body height. Results: There was no significant difference in the group’s mean LESS scores under all the tested conditions (p <.05). Conclusion: The group’s mean LESS scores was similar when college-going baseball player performed maneuvers with landing distances of 40 %, 50 %, and 60 % of an individual’s body height. For testing the LESS, we recommended that the coach set a landing distance of 40 % ~ 60 % to reduce the difficulty of the test process.
