I’m sure Mike will answer your question, but my my two pennies worth…my understanding is that static stretches followed by dynamic activity will not hinder your power output. I like the pattern jog, static stretch, general drills, event imitations, compete. (Example for a sprinter: jog, static, sprint drills, strides, a few block starts, compete.) I have used this pattern with field athletes at all levels up to World Championships and have found no reason to change. I like to have the same pattern (as close as possible) before all training sessions as well. One or two athletes pefer not to stretch specific body parts before competition/training (eg I have a discus thrower that doesn’t like to stretch her chest muscles before throwing — so instead she does this after practice.)
