Give an example of an antagonistic pair
Biceps and triceps, quadriceps and hamstrings
What happens with a antagonistic pair
One muscle contracts while the other relaxes to create movement
What is the name of the muscle for the buttocks

What are isotonic muscle contractions
These are contractions that result in movement
What are isometric muscle contractions
This is where muscles contract but there is no visible movement
How do you treat soft tissue injuries
RICE (rest,ice,compression, elevation)
What are the short term effects of physical activity
Increase In muscle tempura true, increase in demand for oxygen, increased production of carbon dioxide, increased lactic acid production, muscle fatigue
What adaptations take place as response of physical activity on the muscular system
Increased size of muscles, increased muscular hypertrophy, increased myoglobin stores, tendons and ligaments become stronger
Why is it important to rest
To reduce the risk of injury, not enough rest can have negative effects on performance,
