The aim of this study is to examine the impact of cognitive-based learning and imagery training on basic tennis skills to students who take elective tennis course. 16 volunteers who take elective tennis course took part in the research. Control and experiment groups are formed by dividing volunteers into two equal groups. Control group (n=8) and experiment group (n=8) have only attended the tennis course and at the end of the first week "Hewitt" test is applied to both groups. After the test is applied both groups continued to attend tennis courses regularly for 8 weeks. Cognitive learning and imagery training is applied on the experimental group (PCG) in addition to their tennis lessons 2 periods of 30 minutes for 2 times per week, control group (PG), on the other hand, only continued the tennis training. At the end of 8th week of tennis courses, "Hewitt" test is applied once more to the control and experiment group. Acquired data is statistically analysed with IBM SPSS 20 package program. In order to compare the acquired between groups, Independent 't' test, in groups Paired Sample T test is used. As a result analyzes, although there is no logical difference between control group and experiment group in pre-test scores, logical differences are determined in post-test scores (p<0.05). While no logical difference is determined in the pre-test and post-test comparison in control group, logical differences are determined in the pre-test and post-test comparison in experiment group (p<0.05).As a result, it is found that cognitive-based learning and imagery training that applied to students has important impacts on basic tennis skills. According to these results, it is that cognitive-based learning and imagery training that applied to students thought to be positive in the development of basic tennis skills and may increase in athletic performance and sporting succession.
