Other than Cadence which is more easily and effectively gathered using cheaper technology, there's not much evidence that any of the other metrics are valuable to a runner.I think that the Lumo has potential, but needs more development. (Early versions of the Lumo have a fault where light causes a bad battery reading, so you have to insert it into its holder the other way round.) (It's not clear why they can't calculate stride length from pace and cadence.) Lumo are planning on adding this metric, along with stride length. As your support leg moves backwards, there is a tendency for the pelvis to twist so the supported side if further back and the side with the leading leg is further forward. This pelvic drop might be a waste of energy, so Lumo recommends it should be under 12 degrees. As you run, your side of your pelvis that is supported by your leg tends to move up and the other side down. (I'm not sure why this is measured as a velocity rather than acceleration.) I'll be curious to see how this compares to RunScribe's foot braking and Wahoo TICKR Run's smoothness. Lumo measures how much your torso slows up on each stride, and recommends that it should be under 1.65 feet/second. 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. Some are part of a runner's 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. It is generally believed that less Vertical Oscillation is a better, but I suspect that this is an oversimplification. This is how much your torso moves up and down with each stride. 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. It's this 9-axis sensor that allows some of the potentially interesting metrics to be gathered. 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 measures a number of aspects of your Running Form, including Cadence, Vertical Oscillation (bounce), braking, pelvic drop, and pelvic twist. Lumo Run is a Running Sensor that mounts on the rear waistband of your shorts. Unlike BSX, who made some of their software open source, Lumo has just disappeared. Update: Lumo has gone bankrupt and as far as I can see their sensors are effectively bricked.
