- What are the three types of muscles? Give examples
The three types of muscles are cardiac, skeletal and smooth muscles. The first type of muscle is the cardiac muscles, the cardiac muscles are muscles that move continuously without control. The second type of muscles are the skeletal muscles, these muscles are the muscles that you find throughout the skeleton and these are also muscles that are controlled by the person. The third type of muscles is the smooth muscles, The smooth muscles are the muscles found in organs such as your intestines, these muscles are muscles that move continuously without control.
- Describe what agonist and antagonist muscles are
Agonist and antagonist muscles are muscles the contract and relax. Agonist muscles are the muscles that contract when you do a knee or elbow flexion and the antagonist is the muscle that lengthens when you do a knee or elbow flexion.
- What are some movements in the body and examples of the movement in a sport?
A movement that you would use in a sport is a elbow extension and you would use it in basket ball when you go to shoot a 3 pointer. Another movement you would use in a sport is knee extension and you would use it in rugby when you go to kick the ball for a conversion.
- Choose one activity we have completed in class and describe what your task was.
The activity that I choose was poke-a-muscle. The objective was to go through the different stages poking muscle different areas of the human body and as you progressed more into the game it got harder and harder. The way that the game helped me was by showing me where all the different types of muscle were in the human body.
Your description of agonist and antagonist is correct, the agonist shortens/contracts and the antagonist muscle lengthens/relaxes. These muscles appear in every movement though, not only flexion and extension. Your examples are great to illustrate where you can see the movements in sport - I am wondering if you can identify the agonist and antagonist for each movement?
