Although in-phase movement patterns are performed more stable than anti-phase movement patterns, the recent evidences suggested that stability during anti-phase movements are affected by the athletes’ level of proficiency. Therefore, this study targets the effect of athletes’ proficiency in stability of bimanual coordination movements. The performance of 30 novice and expert athletes of hip hop during two selected in-phase and anti-phase movement patterns was recorded using six, 100 Hz cameras in 3D format. Data was being processed using MATLAB software and analyzed afterwards. The results of two-way factorial analysis of variance (ANOVA) with (α≤0.05) showed that stability during in-phase movement pattern is identical in both groups of novice and expert athletes. It is also noted that novice athletes’ movement is more stable during in-phase pattern compared to anti-phase pattern, which had no change during in-phase and anti-phase movements in expert athletes. The result of this study discusses the effect of practice on acquiring proficiency in performing anti-phase movements.
