Implementation of Sport Science Coaching: Improving Strength and Conditioning Performance of Tennis Junior Athletes

the purpose of this research is to examine the improvement of strength and conditioning of performance for junior-aged tennis athletes, especially strength, speed, and endurance, by using sport science and A T-test which was used to assess and measure the improved strength, speed and endurance of the experimental research method. The tests subjects for this research were 13 athletes of “Tennis Plus” in Bandung City, Indonesia, consisting of seven male and six female juniors. This research used 3 instrument tests: the first instrument test for strength was the “push up”, the second test for speed was a 20-metre sprint, and the third test for endurance was a “bleep” test. The results showed an increase in physical conditioning, comparing the pre-test and post-test instrument test scores, comparing t-count with t-table with significance level of 0.05. Initial test results and final tests for strength obtained a t-count = 3.09, for the speed tests they obtained a t-count = 2.05, and initial test result and final test for the bleep test and endurance obtained a t-count = 1.80, with t- table value = 1.71. The conclusion from the research showed that the application of a sport science-based training program increased the physical conditioning (strength, speed and endurance) of the junior tennis athletes.

This study analyzes the impact of sport science on junior tennis athletes' physical conditioning.
