The purpose of this study was to investigate the effects of receiver’s moving speed and passer’s skill level on intra-limb coordination patterns(angle-angel plots and cross-correlational coefficients) among shoulder, elbow, and wrist joint of right arm during passing in basketball. The subjects(five novices and five experts) were required to make a passing in coincidence with an experimentally manipulated moving light signal in randomly presented three different light speed(1.5m/s;3.0m/s;4.5m/s). Qualitative analyses of angle-angle plots disclosed that 1) passer’s skill level had differential effects on all angle-angle plots, 2) receiver’s moving speed had no differential effects on angle-angle plots in novice, but expert appeared different decoupled coordination patterns according to increasing stimulus velocity. Quantitative analyses of angle-angle plots using correlational coefficients revealed that 3) novice was high correlational coefficients in shoulder angle vs elbow angle plots(x-axis) as compare to expert. These results mean that novice adopted the freezing strategy of degrees of freedom in order to increase movement controllability, but expert accepted the releasing of degrees of freedom, resulted in enhancing movement flexibility. We suggested in based on these results that research paradigm for temporal accuracy should shift from information-processing approach into dynamic system approach focusing on coordination patterns, stability variables, and control parameters in the future.
