Tracking dots on the jointsKneecap force, each landingPlumb, landing ruler and bounce gaugeAt a steady 10 km/h, step length is simply speed divided by cadence. Taking 10 % more steps per minute makes each step about 9 % shorter, so the heel lands closer under the body and the body bounces less. In a lab study of 30 healthy runners, modelling showed that a 10 % higher step rate lowered the peak force behind the kneecap by about 14 % per step, and a 10 % lower rate raised it by about 15 %.The Creator 600 sees a run the way this drawing does: a depth camera under the screen tracks the joints and reports cadence, step length, bounce and vertical ratio. Its knee and hip load rating is the machine's own estimate from that tracking, not a force measurement.Group averages from healthy runners, not a prediction for you. More steps per kilometre partly offsets the lower load per step, and there isn't enough evidence yet that changing cadence prevents injury. At this pace most recreational runners take about 155–175 steps a minute; 180 isn't a target for everyone. Any change starts from your own numbers in the review after your run.
