What it is
Impact measures the strength of the forces that your body experiences as you contact the ground. A lower impact score suggests that you are stressing your body by exposing it to large forces while a higher impact score suggests that you are mitigating the stress that your body experiences.
Why it matters
- High impact forces linked to stress fractures and joint pain
- Cumulative impact stress can lead to overuse injuries
- Lower impact improves running economy
- Especially important for older runners and those with joint issues
