The purpose of this study was to investigate the effects of receiver's moving speed and passer's skill level on arm control mechanism of passing in basketball using phase plane plots(angle-angular velocity plots) for the three joints of right arm. Four novice players along with four expert players were required to make a total of 15 passes 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 the phase plane plots of shoulder, elbow, and wrist joint disclosed that 1) stimulus velocity had no differential effects on phase plane plots meaning joint control mode in both expert and novice, and 2) passer's skill level had differential effects on phase plane plots of shoulder and elbow joint. Expert accepted the position-dependent control mode as in springs or pendular in shoulder and elbow joint during passing. But novice operated elbow joint in smooth accelerations and decelerations, in which reversals occurred only at movement extremes. 3) There was no differential effects in wrist joint as a function of passer's skill level. We suggested in based on these results that research paradigm for temporal accuracy should shift from information-processing approach measuring temporal-spatial timing errors, movement time(MT), and reaction time(RT) to dynamic system approach focusing on coordination patterns, control variables, and control parameters in the future.
