BMX Cycling Events, London 2012. BMX is one event I really don’t understand, in particular how it fits into the “movement pattern” approach. On the stand start, the athlete translates forward, pivots the torso/pelvis on the shoulders and extends the downstroke limb. Similar to what I described for the BMX-stand start at the track, and named as such for its resemblance to that movement. The stand starts here are strong and crisp; they get up to speed quickly, and really get the crankarm moving from the very first effort. Identifying a movement pattern is so difficult in the guys, primarily because of the speed and camera perspective. The ladies are no bargain either, but there is an inkling for the hip hike motion, and first half of the course is when you may be able to see this. When the rpm is on the low end, the athlete can take more time to let the movement pattern unfold, in BMX the rate is so high that the movement needs to be very compact and quick. Slow motion video would resolve that issue on short order.
The wipe outs-face plants were remarkable, it seemed they caught the rear wheel at the top of those undulations and momentum drove the athlete over the handlebars. Tough kids out there.
This leads to the editorial portion of the blog (seem to be doing a lot of that lately, and getting myself in hot water at times). About 10 years ago, or so, BMX riders were being recruited for the track, in particular from the success of those athletes in other countries. One reason may be their ability to recruit a high rate of quality movement, though there they would need to adapt their movement pattern to the higher gears and overall different position with the fixed gear. It’s not a given there would be a good transition from this cycling event to the track, especially from BMX. The point is that the coach should be able to recognize whether the athlete would be able to make the transition a successful one, and then be able to guide that transition.
