After this mornings workout and watching a presentation on training adaptations, I don’t believe in conventional energy system development. Placing conditioning into convenient pie charts or ATP flow charts are nice in the classroom but are we getting the wrong information? Now that I am re-reading the Buchheit and Bishop sprint information, I am thinking we need to look at byproducts more than substrate utilization. So the big question is, does this change anything? Yes! Coaches need to focus on velocity and distances more than biochemistry. While the physiology of exercise is important, the most vital information is speed and velocity decay (fatigue). Instead of isolating energy systems or even combining them, focus on what biomotor abilities create changes in speed and repeating speed. Some of the best coaches in the world don’t have exercise science degrees and they succeed by focusing on time and distance.
