The Effects of Vision Training Applied to Kumite Karate National Team Athletes
A study testing Vision Training Program and Routine Training Program in people with Health Individuals and Atlhetes, run by Marmara University at 1 site in Turkey (Türkiye).
Trial summary
This study examines the effects of visual training applied to professional kumite karate athletes. In karate, rapid decision-making, opponent perception at the right time, effective implementation of strategic moves and reaction time are largely dependent on visual perception skills.

About this study
This study examines the effects of visual training applied to professional kumite karate athletes. In karate, rapid decision-making, opponent perception at the right time, effective implementation of strategic moves and reaction time are largely dependent on visual perception skills. In this context, our study investigated how vision training improves visual acuity and sportive performance of kumite karate athletes.
Read the detailed description
Before the study, ethical approval was obtained from Marmara University Faculty of Medicine Ethics Committee with the number 09.2024.611. The study was started with 24 national athletes from Kocaeli Metropolitan Municipality Kağıtspor Team and was carried out on 23 athletes after one athlete in the control group was injured. The athletes who were examined by an ophthalmologist before the study, who did not have any visual problems and who did not have any surgical operation and/or injury history that would adversely affect the balance in the last 6 months were randomly divided into 2 groups. The 12-member vision training group was subjected to a vision training programme that included eye exercises accompanied by a physiotherapist for 3 sessions per week in addition to their routine training for 4 weeks, while the control group continued their routine training. At the beginning of the study (week 0) and at the end of the training (week 4), 't ruler-nelson hand reaction test', 'sit \& lie flexibility test' were performed by another physiotherapist, and 'snellen test' measurements were performed by an ophthalmologist for 'visual acuity' evaluation of the athletes. The researcher who performed the reaction time and flexibility measurements and the physician who assessed visual acuity performed the measurements without knowing which group the athletes were in. After statistically homogeneous-normality evaluation of the groups, Independent Sample t Test was used for comparison of descriptive characteristics between the groups. Mixed-order analysis of variance (ANOVA) was used to compare the variables in the groups according to the follow-up times. Bonferroni correction was applied for the comparison of main effects in the analyses. p<0.05 was considered statistically significant.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Vision Training ProgramOther
Vision Training Programme: A training programme including exercises such as saccadic movements of the eye, spiral movements, converging-diverging exercises, peripheral walking was applied.
Routine Training ProgramOther
All athletes continued their routine training programmes planned by the national team coaches for karate sport during the training period.
| Study group | Role | What they receive |
|---|---|---|
| Control Group | Active comparator | The karate athletes in the control group continued their routine training planned by the national team during the study. Receives: Other: Routine Training Program |
| Vision Training Group | Experimental | The karate athletes in the vision training group participated in a vision training programme that included eye movements and was applied by one of the researcher physiotherapists in addition to their routine training planned by the national team. The application was applied for 10 minutes in 3 sessions per week for 4 weeks. Receives: Other: Vision Training Program; Other: Routine Training Program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Acuity Assessment
Visual acuity was assessed by an ophthalmologist using a Snellen chart.
Measured: Pre-study (week 0) and post-study (week 4)
Secondary outcomes (2)
Reaction Time Assessment (cm)
It is a test that measures reaction time to visual stimuli. In the hand reaction test, the ruler is placed between the fingers of the hand. The practitioner holds the ruler by the tip and above. He/she releases the ruler a while after giving the ready signal. The subject tries to catch the ruler as soon as possible. The reaction time is calculated and recorded according to the distance at the point of catching. 3 repetitions are done and the average value is recorded.
Measured: Pre-study (week 0) and post-study (week 4)
Sit & Reach Test (cm)
Sit on the floor and rest bare feet flat on the test bench. The torso (waist and hips) is tilted forward and the knees are asked to reach as far as possible forward without bending the knees, with the hands in front of the body. The subject tries to reach the farthest point in this way and waits 2 seconds at the last point and the value is recorded. The tester stands next to the subject and prevents the subject's knees from bending. The test is repeated three times and the average value is recorded.
Measured: Pre-study (week 0) and post-study (week 4)
