What is the main difference between normal calf muscles and SCP calf muscles in the development of force?
The SCP curve is shifted to the left and steeper. -
Where is the sarcoplasmatic reticulum located?
Just below the sarcolemma, around the myofibril. -
Why is the A-band anisothrophic?
Because it contains both myosin and actin. -
What is the main effect of lengthening Nebulin on actin?
It will increase the length of the actin filaments. -
What happens to a sarcomere when you stretch it?
- titin stretches
- nebulin stretches
-
What should you keep in mind when measuring the sarcomere-force relationship?
The different lengths of the different sarcomeres. -
What do the normalized curves of the sliding filament theory give you for information?
Mechanical properties. -
What can you say about the velocity dependent properties of sarcomeres at different lengths?
Velocity dependent properties of sarcomeres are the same at different lengths. -
How can you explain the force-length relationship that shows exponential decline in force?
The potentially different length distribution across the fiber. -
How to optimally determine the force length relationship?
- maximal activation
- length normalization
- no fatigue
- Higher grades + faster learning
