Is There a Connection Between Physiological Testing and Cycling?

In cycling, the metrics that we have, it's an embarrassment of riches. And there are certain things, especially with power, where we know what is necessary for a high level of performance but not sufficient all the time. A lot of us don't have training criteria that we can go to once or twice a week and work on those soft skills. It's hard to get a chance to practice these things if you only get five races in a year.
