The Difference Between an Isotonic and Isometric Contraction
WebApr 12, 2024 · Isotonic contraction has two subtypes; concentric and eccentric. Concentric contraction is when the muscle length shortens, while eccentric contraction is when the muscle length increases. This … WebWhich statements regarding coactivation are true and which are false? 1 pts True False Coactivation is associated with a larger amplitude EMG recording from the agonist muscle compared to that in the antagonist muscle Coactivation is thought to stabilize the joint during isotonic contractions.
