چکیده

هدف از این پژوهش، بررسی اثر یک برنامۀ تمرینی منتخب بینایی و دو مهارت مختلف تنیس روی میز بر برخی مهارت­های بینایی دانشجویان پسر جوان بود. شرکت­کنندگان پس از شرکت در آزمون­های اولیۀ غربالگری     بینایی­سنجی، به­صورت تصادفی به چهار گروه تقسیم شدند که عبارت هستند از: گروه­­ تمرینات بینایی و     سرویس­­­های ­­تاس تنیس روی میز، گروه­ تمرینات بینایی و درایو فورهند تنیس روی میز، گروه­ ­­تمرینات بینایی و گروه­ تمرینات ورزشی (درایو فورهند و سرویس­های­ تاس تنیس روی میز). پیش و پس از هشت هفته تمرین، آزمون­های استاندارد بینایی­سنجی از تمامی شرکت­کنندگان به­عمل آمد. تحلیل واریانس مرکب چهار (گروه) × دو (زمان) نشان می­دهد که پس از اتمام هشت هفته تمرین، گروه­های یک و دو در حرکات ساکادی، گروه­های دو و سه در سهولت تطابقی­، گروه­های یک، دو و سه در زمان واکنش بینایی و درنهایت، گروه یک در هماهنگی چشم­ـ­دست، بهبودی بیشتری نسبت به گروه­های دیگر دارند؛ بنابراین، می­توان نتیجه گرفت که به­منظور بالا­بردن مهارت­های بینایی خاص یک مهارت ورزشی، تمرین آن مهارت به­تنهایی کافی نیست. بلکه، انجام تمرین ورزشی به­همراه تمرینات بینایی مربوط به آن می­تواند بهترین نتیجه را به­همراه داشته باشد. دراین­صورت، هم نیازهای ادراکی ـ حرکتی مهارت­ مورد­نظر از طریق تمرین تخصصی ورزشی بهبود می­یابد و هم تمرین بینایی می­تواند به­عنوان عامل کمکی، نیازهای بینایی مهارت­ را توسعه بخشد.

چکیده [English]

The aim of present study was to investigate the effect of training visual and two different table tennis skills programs on some visual skills in male students. All of the participants completed the optometric screening tests and then were randomly assigned into four groups: 1: visual training &high toss service; 2: visual training & forehand drive; 3: visual training; 4: service & drive training. Before and after eight weeks subjects participated in some standard optometric tests. Mixed ANOVA 4 (group) * 2 (time) indicated that saccadic eye movements in the groups 1 & 2; facility of accommodation in the groups 2 & 3; visual reaction time in the groups 1, 2 & 3 and eye-hand coordination in the group 1 had more improvements after eight weeks (P<0.05). Therefore, we can conclude that exercising the sport skills won't be sufficient for enhancing their special visual skills. It seems that visual and sport training together will have the best results. As both the perceptual-motor and visual needs can be promoted.
