Explain how each of the three principles of cardiovascular fitness can lead to injury if they are not adhered to properly.

Answer:

Overload means asking the body to do more than it is accustomed to; too much overload can cause strains, stress injuries, or exhaustion. Progression means increasing exercise demands gradually; progressing too quickly can injure muscles and joints before they have adapted. Specificity means training the body for the activity or fitness goal. If training does not prepare the muscles and movements needed for an activity, the person may be more vulnerable to injury when performing it.
