Final answer:
The phases belonging to the flexibility continuum are functional flexibility, active flexibility, and corrective flexibility, which are essential for improving range of motion and muscle function.
Step-by-step explanation:
The three phases that belong to the flexibility continuum are functional flexibility, active flexibility, and corrective flexibility. These flexibility training techniques are used to improve the range of motion of the muscles and joints. Functional flexibility is focused on basic range of motion and daily movement patterns. Active flexibility involves the ability to hold extended positions using only the tension of the agonist muscles.
Corrective flexibility is designed to correct muscle imbalances and improve muscle function. Ballistic flexibility is not considered part of the flexibility continuum as it is a more dynamic movement that might increase the risk of injury if not performed correctly. It's important to practice these types of flexibility exercises safely and effectively to enhance overall performance and reduce the risk of injury.
