| Summary: | 碩士 === 中國文化大學 === 體育學系運動教練碩博士班 === 98 === The purpose of this study was to investigate: (1) how to anticipate spin of serve among table-tennis players with different skill levels influenced by receiving different perceptive trainings; (2) how different among table-tennis players with different skill levels in pre-cue availability to spin of serve. Subjects took perceptive trainings for 3 weeks continuously, 3 time per week, and with repeating 2 kinds of 5 players serving actions vedio twice in each time. The experiment lasted 9 days totally, and used 48 table-tennis players with different skill levels as subjects (34 males, 14 females, age: 13.66±.75yrs, height: 162.20±8.27cm, weight: 53.5±10.73kg), and was separated them into 6 groups: Perceptive Training I Experts, Perceptive Training II Experts, Control Experts, Perceptive Training I Normal, Perceptive Training II Normal,Control Normal. The subjects’ serving of left sidespin / left side backspin were recorded from the front, and were edited into tests with scenes of 1000ms, 800ms, 600ms, 400ms and 200ms before serving by using time masking method, and letting the subjects to judge the spin nature of the left sidespin. The data collected were analysied by SPSS, with 3-way ANOVA and 2-way ANOVA, the significance level was set at α＝.05. This study concluded that: (1) The anticipation to serve of table-tennis players with better skill levels were better than normal players. (2) Perceptive trainings showed no significant influence on players’ anticipation to serve. (3) The pre-cue availability at different time were significantly related to anticipation; in other words, the longer the time was from serving, the availability to anticipate was lower,and the pre-cues for anticipation were fewer (1000ms<800ms<600ms<400ms<200ms). (4) No significant difference was shown between two groups on the pre-cue availability.
