of constant speed become shorter as speed increases: Subject A reached 900 deg/s.
No conventional systems have, to our knowledge, recorded measurement results
for such rapid movement areas, so low inertia properties appear to have produced
such results. Although subject B failed to reach reference speed of 800 and
900deg/s, this brake-alone system helped complete experiments without forcing
subjects to excess.
Figure 11.12
shows the relationship between exercise speed and operation
torque in experiments. Operation torque was obtained by averaging the range
of angles where normal and isokinetic control was achieved. Black circles indicate
