An Examination of the Effect of 'Hit-Turn Tennis Test' on Two Different Protocols in Pre-Pubertal Tennis Players to Heart Rate, Total Distance Runned and Perceived Difficulty

Aim: The aim of the research, Hit-Turnu Tennis test, fixed with punches against the top of this test modified by downloading thrown my heart made on kick against the top speed is defined as the total requirement distance and examine the impact of the perceived difficulty. Material and Methods: The ages of the athletes were included in our study 12.7±1.75 years, height of 155.2±3.1 cm, body weight 50.9±4.78 kg, training age was determined they did was 6.7±1.5 years and a week was 5.7±0.4 hours of training. Every athlete and tennis Hit-turn test against a stationary ball, as in the original, but they also perform this test by hitting the ball against oncoming traffic by modifying. Both tests from applying their athletes run totals, heart rate and difficulty during tests perceive degrees were recorded. After the data collected during both tests calculated descriptive statistics, the differences between the differences between the two groups paired t-test to examine test (paired-samples) were analyzed. Results: Hit Tennis athlete-turn test during the test, the modified test Hit-turn compared to 124 m They travel a greater distance. This difference was statistically significant (t:2.915; p<0.006). In addition, heart rate values are observed to be similar to each other when both tests. When we look at both testes of athletes perceived degree of difficulty Modified Hit-turn test it was found to be more compelling by athletes. Conclusion: As a result, the modified test Hit-Turn tennis athletes to hit the balls by other net, than they do to kick a stationary ball is believed to spend more effort.
