What is an isotonic contraction?
When the muscle contracts to create movement
What are the two types of isotonic contraction?
Eccentric
Concentric
What is an eccentric contraction?
When the muscle lengthens as it contracts
What is a concentric contraction?
When the muscle shortens as it contracts
What is an isometric contraction?
When the muscle remains the same length as it contracts
