PT Inquest 320 Recreational Running Injury Risk Factors
Nov 28, 2023
The podcast delves into a study on recreational running injury risk factors, discussing the frustrations in the field. They explore knee valgus at toe off, thorax drop, and foot pronation as potential risk factors. The speakers highlight the importance of tracking injuries in recreational runners and the need for accessible research publications.

Episode notes
Statistical Significance ≠ Clinical Meaning
- Small kinematic differences can be statistically significant yet clinically meaningless.
- Knee valgus at toe-off is implausible as a major injury mechanism given low knee loading at that phase.
Tiny Effects Lost In Large Variability
- Reported mean differences (≈1°) were smaller than group SDs (~3°), indicating noisy effects.
- Small effect sizes with large variance undermine confidence in practical relevance.
Sample Foot-Strike Mix Shapes Injury Pattern
- High proportion (≈37%) of non-rearfoot strikers likely explains many calf and lower-leg injuries.
- Sample composition (foot-strike mix) shapes observed injury patterns.
