Final answer:
The effect that a client who becomes injured will experience until they return to activity is reversibility. Reversibility refers to the loss of physiological adaptations that occur as a result of training when training stops or is reduced.
Step-by-step explanation:
The effect that a client who becomes injured will experience until they return to activity is reversibility.
Reversibility refers to the loss of physiological adaptations that occur as a result of training when training stops or is reduced. When a client is injured and unable to participate in training, the adaptations they have gained will begin to reverse.
For example, if a client has developed strength and muscle size through resistance training, but then stops training due to injury, they will experience a decline in their strength and muscle size over time.
