Effect of skill level on variability of intra limb coordination and control variables in top spin strike

The purpose of this study was to examine the effect of skill level on variability of intra limb coordination and control variables in top spin strike. The 16 participants of this study were divided into two groups of Skilled and Novice. The Skilled group was consisted of players who ranked as 8 top in national ranking at their age stage and the Novice group was consisted of players who recently learned the top spin skill. They performed 10 top spin strikes with emphasis on speed and accuracy. Movement kinematics were recorded and analyzed. There was a difference between these two groups in variability of intra limb coordination (p<0.05) and the Skilled group performed more consistent. However, there was not any differences between these two groups in movement control variables (all p>0.05). This study showed that the skilled performers have more consistency in their movement patterns, while it could be no difference with novice performers in control variables as cause of task constraints.
