Swimming and bone density
Also called: swimming bone loss, is swimming good for bones
What it means
Swimming and bone density refers to the fact that swimming, while great for cardiovascular fitness and joints, is a non-weight-bearing activity that doesn't strongly stimulate bone to get stronger.
If you're relying only on swimming for exercise, your bones may not be getting the loading signal they need to stay strong as you age.
Swimming is a wonderful low-impact activity for your heart, lungs, and joints, but it doesn't send much of a signal to your bones. Bone adapts to forces like gravity and impact pushing against it, and water supports your body weight instead of loading it. That's great if you have arthritis or joint pain, but it means swimming alone won't do much to build or maintain bone density.
This isn't about swimming causing bone loss directly - it's more that it doesn't provide the stimulus bone needs compared to weight-bearing or resistance activities. Studies looking at competitive swimmers have sometimes found lower bone density than athletes in impact sports like running or jumping, which fits this idea that bone responds to the type of loading it experiences.
If bone health is a goal, swimming works best as an addition to, not a replacement for, weight-bearing exercise and resistance training. Walking, resistance training, and other activities that load your skeleton against gravity give bones a reason to stay strong, while swimming keeps you fit and moving without stressing joints.
Swimming is great for fitness and joints, but being non-weight-bearing means it barely stimulates bone to strengthen.
