STUDY ON PHYSICAL TRAINING IN TENNIS PERFORMANCE

Abstract. The purpose of the research is to determine and explain the effects of a combined workout training consisting in tennis specific sprints combined with a plyometric training. Our objectives were to analyze the effects of this type of combined training on the variable performance movements in tennis. This training has been performed for 10 weeks, three times/week with a total of 30 sessions. Forty-eight male adolescent tennis players, aged between 14 and 16 years old, participated in this study. They were divided into two groups, a control group of 23 subjects and an experimental group of 25 subjects. The participants had to have a minimum experience of 2 years of participating in competitions at a national level. The physical tests that have been used to measure their performances were: added steps, the Spider test, Illinois agility test and T-test. The statistical program used for analyzing the data was the program named SPSS version 24. To verify the obtained results, several statistical tests have been used, such as T-Test for independent samples, Pearson correlation and paired t-test. Following statistical analysis of data, it was concluded that the two groups differ significantly in terms of tennis movements performance, after the application of the training program (the results of the experiment group are better than those of the control group at the end of the intervention).
