UNSTABLE PLATFORM TRAINING IN TENNIS PLAYERS

The constant maintenance of muscular strength is a highly relevant care in training for tennis practice. The unstable platform is developed with the improvement of modern and technological resources, and the need to verify its effects on the athletes’ physical fitness is requested.

Objective:

Study the effect of unstable platform training on tennis players’ balance ability and assertiveness.

Methods:

12 male tennis-practicing students of the Beijing Sports University School of Education 2020 class were randomly selected as research volunteers. Through a literature search, data statistics, and other methods, they were randomly divided into an experimental group and a control group. After 6 weeks of traditional training in the control group and the addition of unstable platform balance training in the experimental group, the results were compared.

Results:

The ability to stand with eyes open on the dominant leg was significantly improved in the experimental group. After routine training and balance training, the athletes in the experimental group had a great improvement in the assertiveness of passes (P<0.05), and the stability of the service was also improved (P<0.05).

Conclusion:

After training, all physical abilities were improved. The unstable platform training is a valid resource to improve athletes’ balance and assertiveness ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
