![]() ![]() The practice of eating and then having some carbohydrate just before the start of an effort reflects a regular practice for endurance athletes. That provided four conditions in the study: high-fat or high-carb meal and a placebo or maltodextrin jelly. Next, they compared these two scenarios, adding either placebo jelly or maltodextrin jelly. In this case, 4 hours prior or after a period of carbohydrate loading. ![]() Another paper sought to elicit the performance benefits of a high-fat meal versus a high-carb meal pre-exercise. In a recent paper, researchers showed that even one high-fat meal pre-exercise may help limit use of glycogen after carbohydrate loading. That is, higher carbohydrate diets shift metabolism to burn a little more carbohydrates for exercise and vice versa. This is an example of his carbohydrate load.Ī potential reason that shorter protocols may be effective is that the body will shift some of its substrate use based on diet contents. In April, David Lipman, Supersapiens' Director of Applied Science and Content, ran the 2022 Boston Marathon. For someone weighing 82kg (180lbs), this makes for a feast. They are now only about 36-48 hours in duration with some suggestions that even as little as 24 hours is sufficient.īut let’s get specific: Dosing of carbohydrate intake is 10-12g/kg of bodyweight (4.5-5.5g/lb) during this time. Modern protocols are much shorter than they were historically. Protocols and practices have evolved over the decades with respect to dosing of carbohydrates, length of protocol, and even whether there was an initial period of reduced carbohydrate intake. The goal is to delay fatigue resulting from low glycogen as long as possible.įirst things first… How do you carbohydrate load? Carbohydrate loading is the practice of systematically increasing carbohydrates during the taper phase of training (see also: doubling down on portions of pasta) to ensure glycogen stores are adequately high before a key event. ![]()
