THE EFFECT OF STATIC AND DYNAMIC CORE TRAINING ON SOME MOTORIC CHARACTRISTIC AND TENNIS SERVICE VELOCITY OF TENNIS ATHLETES

The aim of this study is to investigate the effect of static and dynamic core trainings on some motoric characteristics and tennis service velocity of tennis athletes. Thirty-six healthy male (n = 21) and female (n = 15) junior tennis players who were between the ages of 10-14 participated in this study voluntarily. Subjects were randomly and equally divided into control (n = 12), static core training (n = 12) and dynamic core training (n = 12) groups. It was implemented the tests of ages, length, weight, body mass index, vertical jump, flexibility, handgrip strength, 10 m speed, y-balance, seated medicine ball throw tests, velocity analysis and radar specifications to subjects attended to this study.The normality distribution of data was checked with using Shapiro- Wilk test and parametric analysis techniques were employed. The differences between pre and post tests were analyzed using Paired Samples T test and variation ratio of numerical difference between some motoric characteristics and tennis service velocity of the training and control groups were analyzed with Independent Samples T test. While there was a statistically significant increase (p <0.05) between some motoric characteristics and tennis service speed pre-post test values of the training group athletes, there was no significant difference in the control group (p>0.05). Core region strength is very important in terms of being the starting point of force and balance in a branch such as tennis where there is a lot of change of direction, mobility and imbalance. The inclusion of core exercises in the training programs of athletes, trainers and conditioners who work with tennis athletes can contribute to the performance development of athletes.
