摘要

本研究的主要目的為探討不同球速與不同來球方向對動作時間之影響。受試者為國立高雄餐旅大學乙組桌球選手，共20人。平均年齡20.56±0.78歲、平均球齡11.5±0.42年、平均身高170.28±2.53、平均體重62.27±0.54。此研究僅推論不同球速與不同來球方向對大專乙組桌球選手擊球動作之動作時間的影響。以擬真方式由真人發球後受試者將球擊回，來探討不同球速與不同來球方向對動作時間（MT）之影響。資料取得主要是藉由LabVIEW程式模組、加速規、紅外線感應器等實驗器材進行相關參數資料的收集，自變項不同球速及不同來球方向，依變項為動作時間（MT）。以相依樣本二因子變異數分析（2-way ANOVA）進行考驗分析。結果顯示：一、不同球速對MT的影響達顯著。二、不同來球方向對MT的影響未達顯著。三、不同球速與來球方向對MT無交互作用產生。

This research aims to discuss the effect of movement time on different velocities and different ball coming directions. The subjects were B class intercollegiate table tennis players of National Kaohsiung University of Hospitality and Tourism, in the aggregate of 20 players. Subjects' average age ±20, length of playing table tennis ±11years, height ±170cm, weight ±62kg.This research only inferences the effect of movement time on different velocities and different ball coming directions to B class intercollegiate table tennis players. To discuss the effect of the movement time (MT) from different velocities and different ball coming directions by taking an imitation of subjects hitting the ball back from real player severing. Data found by the experiment from LabVIEW program module, acceleration sensor and infra-red senor. Take the independent variable as different ball velocities and directions while dependent variable as movement time (MT). Analyze by 2-way ANOVA. The result shows: 1. The effect of different velocities to MT reaches significant standard. 2. Different ball coming direction to MT did not reach significant standard. 3. Different ball velocities and different coming directions to MT did not exert an influence of interaction.
