目的：本研究將針對青少年網球選手慣用手、非慣用手的握力表現與網球拍重量的相關性進行分析。 方法：本研究對象為曾接受專業訓練的青少年網球選手共 25 位，研究人員使用Ert 300球線測磅器測量受試者球拍直線與橫線的磅數，並且記錄球拍的重量，再以Jamar握力器紀錄慣用手與非慣用手各三次握力的平均測量值。 結果：本研究結果發現球拍重與身高、體重、年齡、慣用手握力、非慣用手握力、兩手總和握力有相關性 (p <. 05)，與球線磅數無相關性。再經由逐步迴歸統計分析後，篩選出「非慣用手握力」，最後進入迴歸方程式的顯著變項只有「非慣用手握力」一項 (p <. 05)。 結論：本研究結論發現，網球選手的身體型態、年齡、握力表現與網球拍的重量呈高度相關，但非慣用手的握力表現才是主要預測網球拍重量的項目，此結果建議網球選手、教練或相關訓練人員可運用非慣用手握力表現選擇適當網球拍重量給予青少年網球選手使用。

PURPOSE: This research was to understand the relationship between grip force and weight of tennis racket for junior tennis players. METHOD: Twenty-five junior tennis players were voluntarily recruited in this study. The researchers taked the Ert300 tennis computer to measure the netters strength of the racket when recording the racket weight. On the other hand, the grip force was taken measurement with Jamar Dynamometer for three times, and the same time to record both hands force. RESULTS: The result found that the racket weight was positive correlated with height, weights, age, grip force of dominant and non- dominant hands, and sum of both hand grip force. But it was not correlated with string strength of racket. Then, by the step- wise regression analysis, only grip force of non- dominant hands was be select into significantly variable parameter. CONCLUSION: The study was revealed the tennis players' body type, age, and grip force were highly correlated with the racket weight. The grip force of non-dominant hands was mainly estimated racket weight. We suggests that the coaches, players or trainers needed considerate the grip force of non-dominant hands to select appropriate weight of the racket for junior tennis players.
