Jockology: training for soccer
This week’s Jockology column rounds up a bunch of research on the optimal preparation and training for soccer: the mechanics of kicking, the physiology of repeated short sprints, the psychology of penalty kicks, the optimal warm-up and nutrition, rapid direction changes, etc. It’s in the form of a big infographic, put together by Trish McAlaster, the talented artist I often work with at the Globe. (We’re currently working a pretty cool graphic for the next column — stay tuned!)
Most interesting bit of info in the current column, for me, was this: when you run a short sprint, you get about 20% of the ATP you need from aerobic processes, and 80% from anaerobic processes. But if you keep sprinting (as you would for a soccer game), the third sprint is already 50% aerobic/50% anaerobic, and the “Nth” sprint is 75% aerobic/25% anaerobic. So if you want to be fast late in the game, you need to fuel yourself like an endurance athlete.
(This info comes from Stuart Phillips‘ chapter in the book Sports Nutrition: From Lab to Kitchen. And I actually simplified the info a bit for the column by combining the contributions from phosphocreatine with other anaerobic sources. The actual split for aerobic/anaerobic/phosphocreatine is 20/30/50 for the first sprint, 50/20/30 for the third, and 75/5/20 for the Nth.)
