Efficacy of Visual Training in Beach Tennis

Study Overview
=================
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.

Primary Purpose: Supportive Care
Intervention Model: Single Group Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Visual training<br>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<br>* Pre-defined visual training protocol including the optometrical unit exercises<br>|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Optomechanical reaction time | The reaction time between the visual stimulus and the motor reaction | 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Static visual acuity | Best-corrected visual acuity in static conditions expressed in logMAR | 8 weeks | 
| Dynamic visual acuity | Best-corrected visual acuity in dynamic conditions expressed in logMAR | 8 weeks | 
| Overall performance during sparing match | Overall performance of the player during the supervised match [percentage of properly conducted series of moves specific to rocket sports] | 8 weeks |
