The Effects of Ten Weeks of Plyometric Training and Specific Lateral Movement Training on U16 Portuguese Masculine Tennis Players
The purpose of this study is to determine the effects of the PLYOSPECIFIC program on the lateral specific movement performed on the weak side of the tennis player. The pursued objectives are to determine if the PLYOSPECIFIC training consisting in a combined training (tennis specific with plyiometric training for strength and speed) performed during a period of 10 weeks, three times per week and a total of 30 sessions have a positive effect on the weak side of the athlete. In the present research, we have had 48 male adolescent tennis players between the ages of 14 and 16 years old taking part. They were divided into two groups: The control group, with 23 subjects, and the experimental group, with 25 subjects. To be eligible for participating in the study, the tennis players needed to have a minimum experience of 24 months participating in national competitions.
The tests that have been used to measure the physical performance are: sprint 5-10 m, long jump, run 6x20 m, side jumps performed on both legs over the gym bench, spider test, added steps test, long jump, side jumps performed on both legs over the gym bench, the spider test, Edgren side steps test, and Illinois agility test. To verify the obtained results we used SPSS 24.
So that we verify the results obtained we used the linear simple regression. The results showed that this program, by practicing the lateral movement and the added steps for the non-dominant (left) side predicts or explains significantly with (p=.000) 85% (R2adj=.85) of the variance of the specific lateral velocity (right side, the dominant part).
