Frequently asked questions
- Why is 1% treadmill incline recommended?
- Research by Jones & Doust (1996) showed that 1% grade compensates for the lack of air resistance on a treadmill, making it more equivalent to outdoor running.
- How much does incline affect pace?
- Roughly 3–4% more effort per 1% grade increase. At 10 km/h, adding 5% grade is physiologically equivalent to running about 11.75–12 km/h on a flat surface.
