[PURPOSE] The purpose of this study was to investigate angles and ROMs of the upper limbs, distances, speeds, and energy consumptions. [METHODS] Four cyclists (two men belong to MH3 and two women WH4) who were registered with the Korea Disabled Cycling Federation participated in this study. Qualisys system was composed of twelve Oqus-500 infrared cameras and QTM software. Experimental protocols were designed to make subjects carry out 9 levels of incremental load exercise consisting 30 seconds of warm-up and 30 seconds of maximal exercise for each level. The analysis of the results has been done with the average values taken from the three times selected motions. [RESULTS] First, men cyclists' patterns of wrist angle were irregularly oval during cranking. Second, increasing load and time of maximum muscle activity were decreased except one excellent cyclist (SM1_Y). Third, time of maximum muscle activity of excellent cyclist was greater than others. Fourth, for women, the most difference in ROM between contralateral muscle groups was the wrist joints bur elbow joints for men. [CONCLUSIONS] These findings suggest that important factors of hand cycling performance were a regular pattern of wrist joint angle and increasing the time of maximum muscle activity.
