Abstract
This investigation Studied the consistency of the within-cycle torque pattern in hand cycling (1) in Subsequent cycles, (2) between different individuals, (3) between different power output levels, and (4) with respect to fatigue. Ten non-disabled male participants performed a progressive peak arm crank ergometry test; a number of 5-minute submaximal tests at 10, 20, 30, and 40 W; and one 15-minute submaximal test at 80% to 90% of their peak heart rate. A hand cycle unit attached to a computerized motor allowed for power Output adjustments and registered position and torque. Variation coefficients were calculated and averaged for evaluation of the pattern consistency. Values were 2.7% to 3.9% for subsequent cycles, 3.2% to 5.3% between participants,, 2.8% between different power Output levels, and 3.1% with respect to fatigue. These results indicate a consistent within-cycle torque distribution pattern for subsequent cycles that is minimally influenced by factors such as power output and fatigue.
