Is it safe for older adults with arthritis to exercise?
My mother is 71 with knee arthritis and believes exercise will wear her joints out faster. Her doctor mentioned physical therapy but she is hesitant. Is exercise safe and helpful for arthritis, or does it cause more damage?
✓ Accepted answer
Yes, it is safe and highly beneficial for older adults with arthritis to exercise, as it helps maintain joint mobility and reduces pain rather than causing structural damage.
- Strengthen Supporting Muscles: The American College of Rheumatology suggests that low-impact strengthening, such as using resistance bands or body-weight squats, supports the joints. Stronger muscles absorb impact that would otherwise stress the cartilage, reducing the risk of injury while improving stability.
- Choose Low-Impact Cardio: High-impact activities like running can accelerate cartilage wear. Instead, recommend swimming, water aerobics, or cycling. The Arthritis Foundation notes that water exercises allow for resistance without gravitational stress, making it easier for seniors with knee pain to move through a full range of motion comfortably.
- Prioritize Consistency Over Intensity: Short, frequent sessions are more effective than long, grueling workouts. Aim for 150 minutes of moderate activity per week, broken into smaller chunks. This aligns with CDC physical activity guidelines for adults, ensuring the body adapts gradually without triggering severe flare-ups.
- Address Fear of Movement: Your mother’s hesitation likely stems from a common myth that rest protects joints. Prolonged inactivity actually stiffens tissues and weakens muscles, leading to more pain. Explain that controlled, guided movement releases synovial fluid, which lubricates the joints and nourishes the cartilage from within.
- Use Professional Guidance: Since her doctor recommended physical therapy, start with a certified therapist. They can design a personalized plan that accounts for her specific limitations. Research from the National Institutes of Health supports that guided physical therapy significantly improves function and lowers the need for surgery in knee osteoarthritis patients.
