Consistency of within-cycle torque distribution pattern in hand cycling

摘要

This investigation studied the consistency of the withincycle 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 nondisabled male participants performed a progressive peak arm crank ergometry test; a number of 5minute submaximal tests at 10, 20, 30, and 40 W; and one 15minute 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 withincycle torque distribution pattern for subsequent cycles that is minimally influenced by factors such as power output and fatigue.
