When you look at the team sports game day data from GPS and accelerometers, they do this nice thing where they separate out the amount of time spent walking, jogging, running, and sprinting. It spits out a nice chart telling you how much each athlete spent in each zone. One problem I have (among many) is that the “sprinting” parameter is often set at a speed some of my endurance athletes could run 10k at. Now, that’s not a problem if you realize what the data is telling you, but the problem is a lot of coaches ignore that fact and just see “sprinting” or “high intensity” running time as the key. So, they go back to their zoned training and program in more high intensity work to correspond with game day activity.
