Fig. 7. Relative effort (%) of vertical, braking and propulsive impulses exerted by
fore- and hindlimbs. Absolute values of total impulse (forelimb + hindlimb)
are indicated to the right. Because the total propulsive impulse on the
decline was extremely low, percent limb effort was not calculated. These
percentages were calculated for illustrative purposes; because they were
calculated from the mean vertical, braking and propulsive impulses for each
substrate slope, testing for significant difference among groups was not
possible. BW, body weight.
