Name the 3 types of muscles
Cardiac muscle
Involuntary muscle
Voluntary muscle
Where are cardiac muscles found?
Heart
Are cardiac muscles able to be controlled?
No, they are not under our conscious control.
They are continuously contracting and relaxing
What do cardiac muscles do?
They pump blood around the body
What causes heartbeat?
Internal electrical impulses and contracts, this causes a heartbeat
Why is blood pumped around the body?
Oxygen can be delivered and waste products removed.
This delivery and removal is the major role of the cardiac muscle when it comes to sport and physical activity
What are cardiac muscles?
The muscle of the heart, which pumps blood around the body
Where are involuntary muscles?
Located through the middle layer of blood vessels and throughout the digestive system.
What are involuntary muscles sometimes called?
Smooth muscles
Do we control involuntary muscles?
No, we have no conscious control over these muscles
Are involuntary muscles important for sport?
Crucial for sport and physical activity as it plays a role in the distribution of blood
What is vascular shunting?
The involuntary muscles controlling the internal diameter (lumen) of veins and arteries.
With vasodilation (widening of the lumen) and vasoconstriction (narrowing of the lumen)
Blood is directed to where it is needed most during exercise
What are involuntary muscles?
The muscles involved in digestion and vascular shunting
Can you control voluntary muscles?
Yes, they are under conscious control;
You decide when, how powerfully you contract them.
Whether you are walking, running, throwing or kicking, voluntary muscles are crucial to creating movement.
Are voluntary muscles important?
Yes, even when sitting you contract muscles to maintain posture.
As a result they are crucial in all sporting and physical activity movements
