Vision is a warning that directs muscles of the body to respond and
gives information about where and when to move. Visual reaction time amongst
athletes is mainly concerned with how fast an athlete reacts to a visual
stimulus. However, little information is available on reaction time (RT),
hand-eye coordination among athletes from different sport branches. In many
sports branches; RT and hand-eye coordination is regarded as a prerequisite for
success. For this reason, the aim of the current study was to investigate RT
differences for eye-hand coordination of athletes from different sports and
sedentary people. Study involved 48 athletes, aged 18-25 from different
branches [basketball (n=6), arm wrestling (n=4), boxing (n=6), football (n=13),
handball (n=4), rugby (n=8), volleyball (n=7)] and 9 sedentary people. Hand-eye
coordination tests were conducted by using reaction development and training
system FitLight Trainer™ (Fitlight Sports Corp., Canada). Test protocol
consisted of 10 series of simple motor reaction task to visual stimuli; each of
the 10 series included 22 reactions. Variables not fitting normal distribution
were compared by Kruskal Wallis H test. Mean reaction time (MRT) was found to
be different among branches (p=0.009). RT for 10 different trials were found to
be different for 3^rd(p=0.038), 4^th(p=0.047), 5^th(p=0.022),
6^th(p=0.044), 7^th(p=0.041), 8^th(p=0.011), 9^th(p=0.019),
10^th(p=0.023) trials. According to results, it can be said that
visual reaction times of field players are very specific and insufficient to
distinguish. During trainings, it may be advisable to have reaction time
development exercises with specific technical/tactical skills related to
branches and positions.

Görüş; vücudun kaslarını yanıtlamaya yönlendiren, nereye ve ne zaman
hareket edileceğine dair bilgi veren bir uyarıdır. Sporcular arasındaki görsel
reaksiyon süresi, bir sporcunun görsel uyarana ne kadar hızlı tepki verdiği ile
ilgilidir. Ancak, farklı branştan sporcuların reaksiyon zamanı (RT) ve el-göz
koordinasyonu ile ilgili bilgiler sınırlıdır. Birçok spor branşında RT ve el-göz
koordinasyonu başarı için ön koşul olarak kabul edilmektedir. Bu sebeple
çalışmanın amacı, farklı branştan sporcular ve sedanterler arasındaki RT
farklılıklarının araştırılması olarak belirlenmiştir. Çalışmaya farklı
branşlardan [basketbol (n=6), bilek güreşi (n=4), boks (n=6), futbol (n=13),
hentbol (n=4), rugbi (n=8), voleybol (n=7)] 18-25 yaş arası 48 sporcu ve 9
sedanter katılmıştır. El-göz koordinasyon testleri reaksiyon geliştirme ve
antrenman sistemi  FitLight Trainer™
(Fitlight Sports Corp., Kanada) ile ölçülmüştür. Test protokolü görsel uyarana
karşı motor reaksiyon görevi içeren 10 seriden oluşmuş ve her seri 22 reaksiyon
içermiştir. Normal dağılıma uygunluk göstermeyen veriler Kruskal Wallis H testi
ile karşılaştırılmıştır. Ortalama reaksiyon zamanı (MRT) branşlar arasında
farklı bulunmuştur (p=0,009). 10 deneme için RT üçüncü (p=0,038), dördüncü
(p=0,047), beşinci (p=0,022), altıncı (p=0,044), yedinci (p=0,041), sekizinci
(p=0.011), dokuzuncu (p=0.019), onuncu (p=0,023) denemelerde branşlar arasında
farklılık göstermiştir. Sonuçlara göre, sporcuların görsel reaksiyon
zamanlarının oldukça spesifik olduğu ve ayırt edici olarak yetersiz kaldığı
söylenebilir. Antrenmanlarda branşa ve pozisyona özgü teknik/taktik becerilerle
birlikte reaksiyon zamanını geliştirici egzersizler yapılması önerilebilir.
