5 snips
Mar 1, 2026 Running is often blamed for joint and bone issues, but is it really that harmful? Scientific studies reveal both risks and benefits. While injuries can occur, running may actually improve bone density and protect against osteoarthritis. The key lies in proper technique and allowing time for recovery. Tune in to uncover the truths behind running's reputation and find out how it can benefit your body.

Episode notes
Running Often Protects Joints And Increases Bone Density
- Running's overall effect is protective rather than harmful for joints and bones.
- Longitudinal X-rays showed 20% osteoarthritis in runners vs 32% in non-runners and marathoners had higher heel bone density (rigidity index).
High Injury Rate Explained By Repetitive High Impact
- Running is repetitive and high-impact, which explains its injury rate.
- A Current Sports Medicine Reports study estimated 50% of runners get a running-induced injury each year, including shin splints and runner's knee.
Impact From Running Raises Heel Bone Density
- Repeated impact from running can increase bone mineral density over time.
- A Madrid study found marathon runners had the best calcaneus density, followed by semi-marathoners, measured by a rigidity index.
