Final answer:
You might not want to provide resistance in the entire ROM during reversal training when an individual is recovering from an injury or has a condition like joint instability or arthritis, to prevent further injury and stress on the affected areas.
Step-by-step explanation:
When engaging in reversal training, which involves alternating between concentric and eccentric muscle contractions, there might be situations where providing resistance through the entire range of motion (ROM) is not advisable. One scenario is when an individual is recovering from an injury and has not yet regained full strength or mobility; providing full resistance might exacerbate the injury or delay healing. Additionally, if the person has a joint instability or a condition that limits their movement, such as arthritis, not applying resistance through the entire ROM can prevent unnecessary stress on the affected areas. In such cases, it is important to customize the exercise to ensure safety and to facilitate optimal rehabilitation outcomes.
