Muscle Mechanics Flashcards
1
Q
What is an isometric action?
A
Muscle generates tension with no change in its length
Muscle torque = load torque
2
Q
what is a concentric action?
A
The muscle generates tension while shortening
Muscle torque > load torque
3
Q
What is an eccentric action?
A
The muscle generates tension whilst lengthening
Muscle torrque < load torque
4
Q
What is the torque equation?
A
T = F x r
5
Q
Where is a pivot found?
A
between the resistive force and effort force
6
Q
What happens if the pivot point is nearer the effort force than the resistive force?
A
The lever will magnify the velocity of the effort force
7
Q
What happens if the pivot point is nearer the resistive force than the effort force?
A
The lever will magnify the effect of the effort force
