The effect of 8-week core training on agility, strength, balance performance and tennis skills on 10-14 year old tennis players

25 tennis players studying tennis at EA Tennis Academy participated in the study voluntarily. First of all, vertical jump, pro-agility agility and star balance tests and ITN Tennis skill test were applied to all participants, then, in addition to tennis training, the experimental group of 11 people was given core training 3 times a week for 8 weeks in a row in line with the literature. The tennis players in the control group continued only their tennis trainings. In order to examine the effect of core training on strength, agility and balance performance and tennis skills, the tests applied in the pre-tests were applied to all participants again at the end of 8 weeks as posttest. Using the pretest- posttest measurements taken in the study, the effect of 8-weeks core training on the strength, reactive agility, balance performances and tennis skills of 10-14-year-old tennis players was determined.
