Nutrition for Athletic Performance and Cognition

January 25, 2020

how do you think about i guess going into performance and athletic performance what about nutrition for optimizing performance i mean even touching on people like haddie and even laura simpson and stuff they're incredibly great gifted athletes as well as competitors. They're super fucking strong as well. So what about nutrition for performance? Are carbs and carb timing important? Yeah, absolutely. Absolutely. I mean, carbs are go juice, right? But it also depends on what your sport is, right? So every man... certain power lifter like a power lifters desire needs to have carbs it's going to be slightly different than say like a an afl athlete right so in in one sport you're using that as a major source of fuel so if i'm dealing with a soccer player afl rugby if i'm dealing with somebody's got to play 90 minutes at a really high level constantly sprinting stopping jogging walking and they're going man um you need carbohydrates to a be able to survive the entire 90 minutes at a high level you also need it for cognition the minute you run out of uh run out of blood sugar your brain starts to shut down you start making mistakes you make judgment errors your fine motor skills start to go away you know so your speed starts to go away and there's there's plenty of research on this where you know they take two soccer groups and one of them goes in fully carb loaded the other one goes in at 50 and they've analyzed how how much time each um each group spent sprinting and how many meters that they actually covered and it's it's drastically um much better to be fully loaded with carbs and then to maintain those carbs throughout that entire game because if you don't your your your performance progressively goes down now if you look at something like a powerlifting where they're mainly staying in you know stored atp and creatine phosphate except for like training in their accessory work they don't have a huge need for carbs other than a you've got to fill in the calories somehow and b the carbohydrates serve to mechanically make you stronger so if i have more carbs on board that means i have more water that means my cells are more or filled out much better which means i have more leverage around my joints so there's still a need for carbs in strength sports where it might be a one rep type of thing but it might be a little bit different than what you're using with a long distance event like a triathlon or or field event where they're actually using a lot of those carbs to delay fatigue and improve cognition over time
