目的：比較軟式網球選手不同準備位置（前衛及後衛軟網選手）技能（包括速度技能、軟網技術技能、耐力技能）的差異。方法：以43 名高中男子軟式網球選手（前衛n=22，後衛n=21）為受試者，設計2項速度技能、15項軟網技術技能（4項發球、4項接發球、2項擊球、4項截擊、1項高壓球）、以及3項耐力技能，共20 項軟網技能測驗，依受試者地域性之不同編排2 梯次，每梯次各有4個測驗日（2日前測、2日後測）之施測日程，每個測驗日分別施測10項技能，採用二因子混合設計變異數分析考驗各項體能之差異（ =.05）。結果：前衛與後衛選手在速度測驗的30 公尺衝刺，接發球技能測驗的低手切削發球時之接發球（左場），截擊技能測驗的正手拍截擊、反手拍截擊、中場正手拍截擊、中場反手拍截擊，以及高壓球技能測驗等 7 項具有顯著差異（p<.05），皆為前衛選手優於後衛選手；其餘14項測驗則不具顯著差異。結論：本研究發現軟式網球的前衛選手明顯在速度性技能、截擊技能與高壓球技能表現較後衛選手為佳，但其他方面即沒有不同，這可能與其準備位置所造成的技能特殊性有很大的關係

Purposes: To comparative with 3 major categories of motor skills of soft tennis (ST) between differences positions (net and baseline) of ST players. Methods: The volunteers were the male high school ST players (net player n=22, baseline player n=21), 3 tested categories of motor skill with 20 motor skill test items designed, 2 for speed, 15 for ST motor skills (4 for serve, 4 for reserve, 2 for flat Shot, 4 for volley, 1
for overhead), and 3 for endurance, and tested by 2 echelon. Each echelon had 4 test days (2 days by first test and 2 days by second test). Each test day tested with 10 motor skill test items. The mix design two-way ANOVA were used to analyze the data ( =.05). Results: The motor skill items between net player and baseline player by speed with "30 m dash", reserve with "reserve during low slice serve (in left receiving
formation)", volley with "forehand volley", "backhand volley", "forehand volley on center line", "backhand volley on center line", and overhead were eminent different (p<.05), and the net player better than the baseline player. But other for 14 test items, were not eminent different. Conclusions: Net players have better speed, volley and overhead performance than baseline players. However, no difference between two
groups, maybe cause by the different preparative positions and characteristics STmotor skill.
