Abstract

Eye and hand dominance, as a laterality index, represents structural and functional asymmetries of brain hemispheres. Their contribution to phylogenic and ontogenetic development of human, have been well documented by neuroscientific data. Since the second half of the twentieth century, researchers and sport psychologists, were concerned with the contribution of hand and eye dominance to aiming skills. The aim of this study was to investigate the role of ipsilateral and contralateral eye-hand dominance in tennis serve accuracy. Forty-one right handed amateur tennis players, 22 males and 19 females, mean age 20,9 (SD= ±0.66 years) participated in this study. The mean training age in this period was one to three years. According to ipsilateral and contralaterar eye-hand dominance, sample was divided into two groups: contralateral eye-hand dominance group, including 21 participants (11 males and 10 females) and ipsilateral eye-hand dominance group, including 20 participants (11 males and 9 females). Hand dominance was defined by two different tests, showing the same results. Participants were asked to serve 20 times (10 serves from the "deuce side" of court and 10 from the "advantage side"). Serve accuracy was examined by two experienced, independent examiners. One way Anova analysis has shown no significant differences in accuracy test between the two groups of contralateral and ispilateral eye-hand dominance. However, contralateral group achieved higher scores in accuracy from the deuce court with mean score 5,71 against 5,45 of the ipsilateral goup. Those findings are in contrast to previous studies with regard to aiming tasks. On another study which is currently in progress, the hypothesis about the impact of ipsilateral and contralateral hand-eye dominance on tennis serves accuracy is being examined in professional tennis players.

“…The one-sided preference or functional advantage of limbs or organs, also known as laterality, reveals the individual's tendency to use coordinated, more accurate and stronger body parts mainly regarding to upper and lower limbs and the brain hemisphere during life. If we use them more often, the movement or work-related tasks will become more economic, confident, and precise (Domino, Świątkowski, & Matłosz, 2015;Hagemann, 2009;Loffing, Hagemann, Strauss, & MacMahon, 2016;Ziagkas, Mavvidis, Grouios, & Laios, 2017). Favoring one hand in everyday life creates a difference within the hands and then, a dominant hand develops.…”
