Examining of the Effects of Target-Oriented Circular Training on Biomotor Features by using Tennis Ball Throwing Machine at 12-14 Age Tennis Performance Sportsmen for 10 weeks

Abstract

Aim: In this work, it is aimed that examining the effects of target-oriented circular training on biomotoric features by using a tennis ball throwing machine at 12-14 age tennis performance sportsmen for ten weeks. Method: This research was implemented on sixteen active licensed athletes who played tennis for at least four years in Ankara. The athletes were randomly divided into two separate groups as the experimental group (n=8) and the control group (n=8). After measuring the height, weight, and fat rate of the athletes, biometric tests were started. Flamingo balance, sit-reach, reaction time, five meters and twenty meters sprints, T-test, and standing long jump tests were performed, respectively. Athletes were get heated for ten minutes before the tests and they were given a trying chance. The best scores were recorded by repeating each test twice. In the statistical analysis of the collected data, IBM SPSS 19 package program was used. In repeated measurements, the results were compared by two-way ANOVA with intergroup, intragroup and post-training data. Results: As a result, between the experimental group and control group data; on averages of T-Test (p<0.139), visual reaction (p<0.001), Flexibility (p<0.024), Vertical Jump (p<0.022), Flamingo Balance right foot (p<0.046) and left foot (p<0.045) statistical significance was confirmed.
