NCT04384302

Brief Summary

The proposed protocol is going to study the importance of wide spread of visual functions defined by but not limited to visual perception, visual function, visual exploration, involved in the performance of beach tennis. The investigators intend to examine the basic and important visual function that are required for the better performance in the field. The aim is to assess the efficacy of general training that uses the visual channel as the main one. The investigators suspects the improvement in the visual and motor skills after a predefined 8 weeks of visual training.

Study Arms (1)

Visual training

EXPERIMENTAL

Pre-specidied visual training methods that use: the Marsden ball, tables that uses green-red visual stimuli, physical reation in response to the visual stimuli that uses the flippers or the preselected distances. One set of exercises per week was prepared. Each visual training will last for 15 minutes and should be performed by the participant in their home (using the telemedicine devices to control the conduction of each exercise) 3 times a week.

Other: Visual training

Interventions

Pre-defined visual training protocol including the optometrical unit exercises

Visual training
