Final answer:
Martha should avoid jogging since it is a high-impact activity that may cause additional joint stress, aggravating her osteoarthritis. Instead, she should engage in low-impact exercises like swimming, walking, or Tai chi, which can help manage symptoms and maintain joint health.
Step-by-step explanation:
Martha, who has osteoarthritis, should avoid c. Jogging as an activity.
For individuals with osteoarthritis, it's important to participate in low-impact exercises that do not exacerbate joint pain or cause further damage to the joint cartilage. Activities like swimming, walking, and Tai chi are recommended because they put relatively little stress on the joints, helping to maintain joint mobility and strengthen the muscles around the joints. In contrast, jogging is a high-impact exercise that can put additional stress on the weight-bearing joints, potentially leading to increased pain and further deterioration of the articular cartilage.
Lifestyle adjustments such as engaging in specific exercises, losing excess weight, and using pain management techniques are key to managing osteoarthritis symptoms. While there is no cure for osteoarthritis, these activities can help in maintaining joint function and reducing discomfort. It is also essential to balance these activities with periods of rest to prevent joint fatigue.
