1
Q
Concentric
A
Muscles appear to shorten
2

Eccentric
A
- Microfibres tears are common➡️Delayed Onset of Muscle Soreness (DOMs)
3
Q
Isometric
A
Muscles contract but stay still while generating force
4
Q
What phase is Concentric?
A
Upwards
5
Q

A
Downwards
6
Q
What happens to the Myosin Heads in Concentric contraction?
A
Myosin drags the Z lines closer together
7
Q
What happens to the Myosin Heads in Eccentric contraction?
A
Myosin heads are overpowered / bent in other direction
8
Q
What happens to the Myosin Heads in Eccentric contraction?
A
Myosin head attached but no sliding of filaments
9
Q
What do the filaments (Actin/Myosin do at Concentric contraction?
A
Filaments (actin/myosin) slide across each other
10
Q
What happens to the Actin Filaments at Eccentric contraction?
A
Actin filaments slide away from centre and sarcomere lengthens.
