Despite a global increase in running participation, with Strava recording a 59% rise in social running event attendees in 2024 and London Marathon applications up 40% since 2024, experts highlight the potential impact of running on joints.
Lauren Borowski, a primary care sports medicine specialist, noted that running involves repetitive pressure, equating to three to four times an individual's body weight with each step. This impact can affect bones and cartilage if muscles are not adequately prepared.
For those with existing joint issues, alternative cardio activities are suggested. Cycling, rowing, swimming, and incline walking are recommended options. These exercises can provide cardiovascular benefits while reducing physical stress on bones and cartilage.
Dr M Claire Coopes-Meske from Good Reps Physical Therapy explained that motion is crucial for joint health, as it releases synovial fluids that lubricate and nourish joints. Alexis Colvin, an orthopedic surgeon, advises seeing a doctor for persistent knee pain or swelling that affects daily activity.
