Force-velocity relation: what is it?
Show the answer
In concentric work, maximal force falls as shortening speed rises.
It is Hill's curve, a hyperbola.
Why is a very heavy load lifted slowly?
- Great force is only available at low velocity
- To save ATP
- Because type I fibres work
- Only out of caution
Show the answer
Great force is only available at low velocity
That is the force-velocity relation.
Maximal isometric force: what is it?
Show the answer
The force at zero velocity, the curve's highest point.
