[*]Placing a general emphasis on biomotor ability W while attempting to maintain biomotor abilities X, Y, and Z could potentially result in an unintentional but beneficial development in X, Y, and Z due to either the crossover effects of training or a delayed supercompensation of traits X, Y, and Z.
I have seen this happen many times as well. When we go into maintenance phases for certain qualities they actually increase. They saying goes they you get better at rest. This is one of the reasons why the overreaching literature is very interesting. There hasn't been much published on it from a perspective outside of lifting and elastic strength work, however. I think this is a big reason why Tony Wells is so successful.
