{{DISPLAYTITLE:Lumo Run Review}}
Lumo Run is a [[Running Sensors| Running Sensor]] that mounts on the rear waistband of your shorts. It measures a number of aspects of your [[Running Form]], including [[Cadence]], [[Vertical Osculation ]] (bounce), braking, pelvic drop, and pelvic twist. Lumo uses a 9-axis sensor, which is a 3-axis accelerometer plus a 3-axis gyroscope and a 3-axis magnetometer allowing it to sense movement far better than sensors that rely on the accelerometer alone. It's this 9-axis sensor that allows some of the potentially interesting metrics to be gathered.
* '''Cadence'''. I believe [[Cadence]] is the single most important running metric, and while Lumo seems accurate, the lack of real time data is especially annoying here.
* '''Vertical Oscillation'''. This is how much your torso moves up and down with each stride. It is generally believed that less Vertical Oscillation is a better, but I suspect that this is an oversimplification. Some are part of a runner's vertical movement [[Vertical Oscillation]] is likely to be elastic in nature (consider a bouncing rubber ball), some of the vertical motion will be while the runner is airborne (ballistic), and some of the vertical motion is the deceleration as the runner lands. So , it seems likely to me that excessive vertical oscillation is bad, but it's a tricky to know what excessive is likely to be, or how to correct it.
* '''Braking'''. Lumo measures how much your torso slows up on each stride, and recommends that it should be under 1.65 feet/second. I'll be curious to see how this compares to [[RunScribe]]'s foot braking and [[Wahoo TICKR Run]]'s smoothness. (I'm not sure why this is measured as a velocity rather than acceleration.)
* '''Drop'''. As you run, your side of your pelvis that is supported by your leg tends to move up and the other side down. This pelvic drop might be a waste of energy, so Lumo recommends it should be under 12 degrees.
