NCT06311747

Brief Summary

30 tennis players aged 12-18, will be included in the study. After their normal warm-up, the participants will make 30 forehand and 30 backhand strokes. Forehand and backhand stroke accuracy rate will be calculated. After a week, additional oculo-motor exercises will be included in the warm-up and the forehand and backhand stroke accuracy rate will be calculated again. The hypothesis that there will be an improvement in forehand and backhand stroke accuracy after oculo-motor exercises will be tested.

Outcome Measures

Primary Outcomes (1)

  • Forehand and backhand stroke accuracy

    30 forehand strokes and 30 backhand strokes will be evaluated.

    baseline and week 1

Study Arms (1)

Oculo-motor exercise

EXPERIMENTAL

Additional oculo-motor exercises will be administered to participants' warm-up before forehand and backhand stroke evaluation. As oculo-motor exercises, 3 different exercises will be applied: stepping exercise with eye movements and head rotation (The eyes are fixed on the thumb and the head rotates right and left and walks 10 steps forward and 10 steps back.), accommodation (First eyes fixed on the near target, then fixed on a target approximately 20-30 m away.) and pen tracking with 5 different movements (Horizontal, vertical, diagonal, circular, infinite eight).

Behavioral: Oculo-motor exercises

Interventions

Oculo-motor exercises will be applied as an intervention. As oculo-motor exercises, 3 different exercises will be applied: stepping exercise with eye movements and head rotation (The eyes are fixed on the thumb and the head rotates right and left and walks 10 steps forward and 10 steps back.), accommodation (First eyes fixed on the near target, then fixed on a target approximately 20-30 m away.) and pen tracking with 5 different movements (Horizontal, vertical, diagonal, circular, infinite eight).
