This article highlights the differences between acute and chronic workload ratios. Take the example of a pitcher that did no throwing over Christmas break and the first week back is expected to reach max long toss distances and throw a bullpen. They essentially went from 0 to 100 in a matter of days. It’s not always on coaches; athletes are just as responsible, if not more, for taking care of their throwing during these breaks. Too much too soon and you’ll be sidelined.
