"Nobody runs, skates or cycles faster from biomechanical evaluation only, no matter how many biomechanical factors you measure, there are always more performance factors to consider and to change (or not)."
A good post from Henk Kraaijenhof which captures some of the technological / if we can measure it, it must be useful / interventionist approach that pervades coaching, particularly for those organisations with larger budgets to spend on this sort of approach. It's never black/white, either/or when it comes to measurement or technology, however it's easy to spend energy focusing on the wrong things.
