Abstract

Today, some researchers have focused on the impacts of new and easily applicable non-invasive methods on physical education. The purpose of this study is to examine the vibration-related acute change in rotary pursuit coordination performance soon after arm vibration. In the study, 27 students in School of Physical Education and Sport were divided randomly into two groups. In order to eliminate the effect of learning, vibration and non-vibration rotary pursuit test was applied to each group rotationally. Group 1 (n_group1=14) was subjected to 4 rotary pursuit (40 s) tests each involving 3 vibration (30 s, 50 Hz, 2 mm) interventions. Two weeks later, the same participants were subjected to rotary pursuit tests with 30 s. rests instead of vibration interventions. Group 2 (n_group2=13) first received the non-vibration test and then the vibration test in the same order. According to the results of repeated measure of ANOVA, a significant improvement (F_(3,24)=9.08, p=0.00) was found in the rotary pursuit performance with vibration (1^st: 28.28±5.21., 2^nd:29.59±4.61, 3^rd: 30.51±5.31, 4^th: 31.42±4.29 s). A significant improvement was not found (F_(3,24)=1.80, p=0.17) in the rotary pursuit coordination practice without vibration (1^st: 27.42±4.80., 2^nd:28.54±4.45, 3^rd: 29.03±3.58, 4^th: 28.60±4.21 s). The study revealed that acute hand vibration positively affected rotary pursuit coordination. This positive impact is considered to have originated from the reconstructive effect on the sense of joint position of acute vibration. It is believed that the results of this research might inform physical education teachers working on hand-eye coordination.
