subjects attained, in increments of 50 mm/s. The maximum velocity attained by
subject A was 500 mm/s.
Subjects B and C underwent similar experiments to determine average muscle
contraction in isokinetic contraction time. Muscle contraction is calculated from
Eq.(11.4)

ing torque measured with the torque sensor in the system.
Fig. 11.16
shows the relationship between average tension in muscle contraction and con-
traction velocity. Symbols are the same as in
