Figure 4From: Viscoelastic properties of the Achilles tendon in vivoAverage Achilles tendon force-elongation curves at the fast and slow loading rates. The data points are given at 10% intervals ranging from 10–80% of maximum voluntary force. The solid line and square markers indicate the fast rate, and the broken line and circle markers indicate the slow rate. Elongation was not significantly different between the fast and slow rates at any force level.Back to article page
