1
Q
What is force?
A
A pushing or pulling motion that changes a body’s star of motion.
2
Q
What is Contraction?
A
The contraction is determined mainly by length and velocity
3

4
Q
What is Force - Velocity?
A
The force a muscle can create decreases with the increase velocity of shortening.
5
Q
What is Force-Length?
A
The active force decreases with the increasing muscle fibre length.
6
Q
Other factors affecting max force Generation?
A
- Pre-streghting
- Muscle fatigue
- Type of muscle fibre
- Frequency of muscle simulation.
