To investigate the outcomes of sports vision enhancement training on softball players, specifically the visual skills and visual function. This will help to develop and hone best practice methods for future research as well as training protocols for athletes.
Read the detailed description
After informed consent is given by each participant, they will go through a pre-training evaluation at the Sports Vision Clinic at University Incarnate Word. The evaluation will include a Senaptec Sensory station evaluation of 10 skills, 1) visual acuity 2) contrast sensitivity 3) depth perception 4) near far quickness 5) perception span 6) multiple object tracking 7) reaction time 8) target capture 9) eye hand coordination 10) go/No go. Other skills will be evaluated and re-measured using different types of equipment for better reliability. 11) visual acuity using Rabin Super vision 12) contrast sensitivity using Pelli-Robson and Rabin Super vision 13) accommodative facility 14) reaction time on Dynavision 15) depth perception on the Howard-Dolman, Randot and Automated Vision Tester 16) vergence ranges 17) accommodative amplitude. At the first evaluation each participant will also be asked to complete an entering questionnaire, and at the last evaluation each participate will be asked to complete an exit questionnaire.
The above-mentioned evaluation of 17 items, will be given to each participant pre-training protocol, post-training protocol and once more after a washout period of 5 weeks.
The training protocol will consist of once weekly training sessions 45 minutes in duration. Every participant will receive the same training protocol the only variation will be level of advancement, some athletes will advance at different rates onto more complex levels of each activity. This is to allow continued improvement of the athletes and maintain motivation. Each training session will consist of the following activities 1) Brock string to improve vergence accuracy and depth perception; 2) Senaptec Strobe glasses while performing toss and catch, to improve concentration and visualization; 3) Eye Metrix double eye speed scanning, activities using a number board, aimed at collecting visual information quickly and accurately; 4) Senaptec Synchrony activities to improve anticipation and timing; 5) Senaptec Sensory Station Near Far, focus and concentration activities to improve eye accommodation accuracy; 6) Dynavision activities to improve reaction time, eye-hand coordination, and central-peripheral processing speeds; 7) Sports Vision Trainer Go/No go activities to improve low contrast and go/ no go decision making; 8) Senaptec Sensory Station spatial memory activities to improve memory span and peripheral awareness. Each activity will be performed twice.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Sports vision enhancement training curriculumOther
A curriculum of 8 sports vision training procedures applied during women's collegiate softball team training. The training protocol consists of once weekly training sessions, 45 minutes in duration.
| Study group | Role | What they receive |
|---|---|---|
| Sports vision participants | Experimental | Women softball team participating in a sports vision training program Receives: Other: Sports vision enhancement training curriculum |
What is being measured
The primary outcome is the main question the study is designed to answer.
Target accuracy
An evaluation to compare how many buttons pressed on Dynavision in one minute to the baseline performed at the study onset.
Measured: Change from baseline at pre-evaluation week 1; to post evaluation at week 12
Reaction time
An evaluation to compare average reaction time of buttons pressed on Dynavision in one minute to the baseline performed at the study onset.
Measured: Change from baseline at pre-evaluation week 1; to post evaluation at week 12
Vergence ranges
An evaluation to compare vergences ranges to the baseline performed at the study onset measured by using free space prism ranges distance and near.
Measured: Change from baseline at pre-evaluation week 1; to post evaluation at week 12
Secondary outcomes (1)
Diminished skills; such as Target accuracy, reaction time, vergences ranges.
To see if 5-6 weeks of not training diminishes visual skills trained.
Measured: Change from post evaluation at week 12 compared to final washout evaluation at week 18.

Questions about this trial
What is this clinical trial studying?
A study testing Sports vision enhancement training curriculum in people with Athletic Performance, run by University of the Incarnate Word at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Target accuracy (time frame: Change from baseline at pre-evaluation week 1; to post evaluation at week 12). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05990036, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2023.
