High-Volume Zone 2 training is about as enjoyable as getting a root canal without the novocaine, but what really grinds my gears is that conventional wisdom dictates we should all be consuming the same meal composition to optimize energy levels during these phases.
Im talking about the standard fare of complex carbs, lean protein, and healthy fats - you know, the whole shebang. But what if I told you that some of the most successful endurance athletes Ive met swear by consuming a disproportionately high amount of protein during these phases? Were talking up to 1.6 grams of protein per kilogram of body weight per day.
Now, before you start throwing around terms like nitrogen balance and protein synthesis, lets get real for a second. What does the actual science say about the optimal meal composition for high-volume Zone 2 training? Is the traditional model still the gold standard, or are there other, more effective ways to fuel our bodies for these grueling phases?
Specifically, what role does protein play in maintaining energy levels during extended periods of moderate-intensity exercise? Should we be doubling down on the protein shakes and chicken breasts, or is this just a bunch of bro-science nonsense?
