“…In the article by Jorge et al [14], they used the same software as in our study, COI-SV, for the analysis of dynamic visual acuity where 147 high-level futsal players were analyzed. In this article, they concluded that dynamic visual acuity varies by playing position.…”

“…Regarding the limitations of our study, the software used in our study has been used in another published research [14]. The decision to use this software is that COI-SV can perform both diagnostic tests and optometric treatments with a specific focus on sports vision.…”

“…As a control group, thirty-five individuals in the same age group without contact with the sport were also chosen. Visual efficacy of all participants was evaluated with the digital system COI-Sport Vision (Centro de Optometría Internacional, Madrid, Spain), choosing the tests that measure the most relevant visual abilities for futsal [12,14]. The reliability of this software is (α = 0.93) [15].…”

Background: Coordination and reaction time are relevant aspects of a sport’s competitive performance within teams. The aim of this study was to explore if a group of futsal players, in a laboratory context, would present better results from actions where vision is prevalent compared to a control group without contact with futsal or any other sport. Methods: The digital system of the COI- SV software was used; six tests were selected, related to coordination (“Eye/hand coordination”; “Coordination and identification”) and reaction time (“Anticipation Time”; “Peripheral response”; “reaction time”; “Visual memory”). Results: Of all the tests performed, only in the anticipation time test did the futsal players obtain better results than the control group. The average time of the failures was lower in relation to the control group. In the others, no differences were found between the two groups. Conclusions: The futsal players did not perform better than the control group in most of the tests carried out, except in the “anticipation time”. Therefore, visual training maybe necessary to improve visual skills and sports performance.

“…Sports vision encompasses comprehensive visual assessment, sports-specific enhancement of visual performance, and ocular protection for athletes, aiming to improve athletes’ performance [ 6 , 7 ]. Studies have demonstrated that athletes have better visual abilities than non-athletes [ 8 ] in terms of larger fields of peripheral vision [ 9 , 10 , 11 ], better dynamic visual acuity [ 12 , 13 ], and more accurate depth perception [ 14 ].…”

Table tennis athletes and non-athletes potentially differ in stereopsis and eye–hand response times (RT), but whether stereopsis correlates with response time has scarcely been discussed. We aimed to compare stereopsis and RT between collegiate table tennis athletes and non-athletes and to examine the correlation between stereopsis and RT. From December 2016 to October 2019, table tennis athletes (n = 80) and non-athletes (n = 56) were recruited. Stereopsis was measured in four modes (A25, A50, R25, R50: approaching and receding directions at 25 mm/s or 50 mm/s). RT was measured with simple and choice tasks at zero, shoulder, and random distance. For stereopsis, the judged deviations were smaller during the approaching phases. Men had smaller A25 than women (p =0.012), whereas table tennis athletes showed smaller R25 and A50 than non-athletes (p = 0.03, 0.01, respectively). RT increased from simple to choice conditions and from zero to random, followed by shoulder distance. Men were significantly faster than women in choice tasks (p < 0.01). Table tennis athletes performed better in RT than the non-athletes (p < 0.05). No correlation was observed between stereopsis and RT (r = −0.01 to 0.12). In conclusion, athletes from table tennis sports showed better stereopsis and RT than non-athletes. Men had better stereopsis and RT than women. There was no correlation between stereopsis and RT.

This research aimed to produce models of hitting practice tools, which could be used in training beginner woodball athletes in Indonesia. A process of research and development was followed after the model of Gall, Gall, XXABSTRACT Borg (2007). Small-scale field trials were first conducted at Gerokgak Woodball Club (GWC), or Gerokgak Woodball Club (GWC) Buleleng-Bali, involving 10 athletes (5 males and 5 females). These were followed by large-scale field trials conducted in Pengkab Woodball Buleleng, or Pengkab Woodball Buleleng-Bali, involving 20 athletes (10 males and 10 females). Data gathered were both quantitative and qualitative. Quantitative descriptive analysis was employed with the (a) observation instruments/observations of the effectiveness of the tool development model; and (b) the athlete response questionnaire as part of the validation process. Qualitative descriptive analysis was applied to data gained from interviews, observations and fieldnotes in processing suggestions for improvement from material experts, media experts, and practitioners. This research produced an effective and appropriate hitting practice tool for beginners in woodball and a guide/instruction on how to use the tool. These wood practice products can be carried or moved in accordance with training needs (portable), can be used to train the consistency of the punch, increase the frequency of hitting exercises, in the open field (outdoor) or in the building (indoor). The wood practice tool can be used by athletes to practice short stroke, medium, long, or finishing/gating.

Static and dynamic visual acuity and refractive errors in elite football players

Abstract: Dynamic visual acuity of forwards is lower than that of other players. Twenty-five per cent of players who need to use visual correction to practice sports actually use it.
