The Effect To Tennis Receive Anticipation Ability By Simulation Anticipation Training For The Tennis-specialty Students

Purposes:To investigate the difference of tennis experts and novices at the receive to predict the use of temporal and spatial cues, clear the expert use of effective temporal clues; On this basis, through intervention the tennis-specialty students eight-week simulation to anticipation training, discussion the effect to tennis receive anticipation ability by simulation anticipation training for the tennis-specialty students.Study One:Convenient select a sports university tennis first-class level athlete 20 players (average age was 24.05±2.481 years,14 male) and 20 tennis novices (average age was 20.80 ± 1.507 years old, male,16). Within three factors mixed design, the argument between the two groups for the sports level, including two expert and novice level, within the set of independent variables 1 was Time block points, including before touching the ball with the racket 160ms,120ms and 80ms three levels, within the set of independent variables 2 was a Space block, including shoulders, torso and racket blocked three levels. The dependent variable are the response time and accuracy. Statistical analysis showed that: 1) the response time was judged experts and novices no significant difference; 2) three times block point, experts predict the correct rate was significantly higher than the novice, and before touching the ball with the racket 80ms, the correct rate the biggest difference. Tips, predict experts than novices started earlier, as time progresses, information specialists available more fully; 3) before touching the ball with the racket 120ms, space and block the sports level of the horizontal accuracy of interaction achieve significant, further analysis showed that when the blocking racket, expert and novice correct rate was no significant difference, and in the blocking shoulder or torso, experts predict the correct rate remained significantly higher than the novice, suggest that before touching the ball with the racket 120ms, racket information is an important clue to the experts anticipation.Study Two:Convenient select a sports university 28 male college tennis-specialty students in the experimental group and 14 (average age was 20.44 ±.629 years), the control group of 14 people (average age was 19.64 ±.633 years). Between groups using longitudinal quasi-experimental design, experimental group for a period of eight weeks, twice a week, every 30 minutes of simulated training anticipation, watching the tennis Grand Slam events in the control group during the intervention. For pre-sentence response and accuracy were measured before and after. The results showed that 8-week intervention, no significant increase of students at the Tennis predict response. Before the ball with the racket contacts 160ms and 120ms, the type of intervention main effect on the correct rate reached marginally significant when the ball before touching the racket 80ms, the type of intervention on the main effect of the correct rate reached significant intervention significantly improved accuracy.Conclusions:1) Tennis experts started earlier than novices of serve to anticipation; before touching the ball with the racket 120ms, information is the key to the racket clues expert use; 2) an 8-week training simulation to anticipation, it is possible to improve the tennis-specialty students tennis receive anticipation ability.
