Wanted to add that the trickle down of focusing on max strength or power to strength-endurance / power endurance is better than the trickle up affect of focusing on endurance aspects.
I guess you could classify strength-endurance and power-endurance in the same category, but I think they are 2 different animals. Two different people with the same strength-endurance could have vastly difference power-endurance numbers and the person with the better power-endurance would win every time. Even someone with better strength endurance numbers and poor power-endurance numbers would lose to someone with greater power-endurance numbers but substantially less strength endurance if the total work in completing the task is within the latter’s power capacity. Like I have said previously distance coaches are notoriously bad for concentrating on volume of work rather than a comprehensive plan focused on work volume in a specified amount of time. Work capacity is endurance related no matter which way you want your pizza cut. For throwers and jumpers Power-Endurance has to be heavily weighted (90% of PE workouts need to be within this realm) towards Power-Endurance of short-durations up to about 5-6s of work (basically 3 consecutive reps max on jumps, throws, or lifts), while all around sprinters (60-400) need it for short and medium durations up to 60s, mids (400-mile) need it up 3-5 minutes, and distance guys (1500-10k) need it up to around 30-35 minutes. I try to stay away from SE work and let it all be PE work, if it starts becoming an SE session I cut it. What is your take on an approach like such? I think PE work should become more specific as the season progresses, I don’t really ever get away from it, in fact I think I do more of it as the season rolls along with sprinters, but of much higher intensities and less volume, a speed/accel (W) day becomes speed/special endurance, while the tempo day (tu) becomes a speed or special endurance day, while Monday stays a speed/accel day, and thursday is extensive tempo.
I don’t typically focus on endurance factors that much anymore because i am out of the business of coaching middle schoolers in cross country. Maybe someday I will go back to doing middle school cross for fun again. It was fun watching my middle schoolers bound and throw 4lb medballs in cross practice.
