There is a specific response to the specific nature of a training load. This specific response will tend to emphasize one or more of the abilities that make up fitness. These abilities are basic and respond well to training. Each exercise in training tends to develop a particular biomotor ability. The game, tennis, requires high level of speed, agility, coordination and endurance. Different training methods are being adopted by tennis players to improve their biomotor abilities. The researcher is interested to find out the effect of core board and slide board training on performance of selected biomotor abilities of tennis players. The subjects, male tennis players (N=45), from the different colleges of Chennai were randomly selected as subjects and their age ranged between 19-23 years. They were divided into three groups namely core training group, slide board training group, and control group on random basis. Pre test was conducted for all the 45 subjects on selected biomotor abilities. The experimental groups participated in respective training for a period of six weeks. The control group did not participate in any of the training programme. The post test was conducted on the above said dependent variables after a period of six weeks for all the three groups. The obtained data were subjected statistical analysis using ANOVA. The results proved the experimental groups proved that core board and slide board exercises were significantly better than control group in improving speed, coordination and endurance comparing control group. It was concluded that core board training and slide board training can be used for improving of specific biomotor abilities of tennis players.
