Which of the following is a contraindication for participation in the AFAP?

Uncontrolled high blood pressure is indeed a contraindication for participation in the Arthritis Foundation Aquatic Program. This is because uncontrolled high blood pressure can significantly increase the risk of serious health complications during physical activity. Aquatic exercise can elevate heart rates and increase blood circulation, which may pose a danger if blood pressure levels are not properly managed. Participants need to be in a safe health condition to engage in any exercise program, especially one involving physical exertion like those offered in aquatic therapy.

In contrast, controlled diabetes, recent knee surgery with clearance from a healthcare provider, and mild osteoarthritis are conditions that can typically be managed or accommodated within an aquatic exercise program. Controlled diabetes indicates that the participant's blood sugar levels are stable, making it safer to exercise. Having clearance for recent knee surgery suggests that the participant is ready to start rehabilitation exercises, and mild osteoarthritis usually allows for light to moderate physical activity, which can actually be beneficial in managing symptoms and improving joint function.
