Swimming For Arthritis | What Makes It So GOOD?

Welcome Back Rheumatology Fans!Swimming is often recommended for people with arthritis, but is it actually better than other types of exercise? The short answer: it depends on the individual.Swimming and water-based exercise can be helpful because the buoyancy of water reduces the amount of weight going through the joints. For example, when standing in water up to belly-button depth, the body is only bearing around 40% of its usual weight . This reduction in joint loading can allow people with painful hips, knees, or feet to move more comfortably and exercise for longer.Water immersion also provides a cardiovascular benefit. The pressure of the water increases venous return — meaning more blood is pushed back to the heart — which makes the heart work slightly harder and therefore provides a cardiovascular training effect . In addition, buoyancy can make it easier to move stiff joints and take them through their range of motion.However, swimming is not without downsides. Many barriers are logistical: travelling to the pool, changing clothes, slippery surfaces, cold environments, and cost. Some people also accidentally overdo activity in the water because the reduced joint loading masks normal pain signals.Ultimately, swimming is a good exercise option for arthritis, but it is rarely the only or “best” option. The most effective exercise is usually the one a person can do consistently and safely.* Water reduces joint loadingBuoyancy can significantly decrease the weight passing through painful joints, making movement easier.* Swimming provides cardiovascular benefitsWater pressure increases venous return, which places a mild training demand on the heart.* Movement can be easier in waterBuoyancy can help people move joints and the spine through their range of motion with less discomfort.* Logistics often limit swimming as exerciseTravel, changing facilities, cost, and cold environments can be significant barriers.* Exercise choice should be individualisedSwimming is helpful for some people with arthritis, but it is not inherently superior to other forms of exercise.Check out our new CPD from PMAP!
