No? I'm saying it's easier to maintain a certain amount of mass than it is to build it.
You've mentioned 4 athletes:
One is a physique competitor (glorified model). Required to hold far less muscle mass than actual bodybuilders, (all of whom eat animal products btw. How many bodybuilders at the mr. Olympia are vegan again? Imagine the marketing opportunities if one of them did go vegan. Why havent they?) Are any of the competitors at worlds strongest man vegan? Is eddie hall, was Ed Coan, Karwoski? Furthermore the phyisque athlete was a vegetarian before he went vegan right around the time he started doing his first amateur shows.
The Oly lifter for team USA finished 11th out of 19. at the olympics 94kg weightclass. He finished 6th at the 2008 olympics in the 85kg weightclass with a better total. So he went vegan in 2014, competed 9 kilos heavier and got worse results. Incredible. I think he just decided he wasn't going to be competitive in anything and made a marketing decision. Wasn't this bloke in the vegan propangada film "game changers"? Smart play. Minor point: Team USA is shit.
Does he say how much plant protein powder he's taking? For the math to work (see above) I bet it's over 3 servings at 90 grams. (which is the equivalent at 3 scoops of whey or 5 scoops if you use the pea protein serving size). Whey protein is mostly a convenience for lifters. I've met national powerlifting champions that don't use it at all (and if you look at the protein contents of a big steak, it's obvious why), and a lot of bodybuilders only use it on a cut because of caloric density.
Okay, what about the all the people above him, you know the ones that had 50kgs more on their total?
The Polish dude you mentioned I cannot find with a quick google, but I'll take your word for it. He's 74 kilos. He barely weighs more than me and I'm a female with 20% body fat. He's certainly explosive, but he's not big at all and quite skinny for a lifter. Protein intake recommendations are based on mass for a reason.
A masters category athlete is by definition not an athlete at the highest level and masters competitions aren't necessarily very competitive.
Are you that interested in strength sports that you know all these relative unknown athletes? Or do you frequent certain pro vegan publications that push these guys and did you buy into the fantasy they sell?
Thinking veganism can be an optimal diet for a person looking to get big and strong is a fantasy as much as thinking jay cutlers pre workout supplement will get you additional gainzzz.
Most people could benefit to get stronger for health (or athletic) reasons. If they don't for whatever reason, it's still a slightly suboptimal diet for some people considering the lack of omega 3 fatty acids and not all humans having great ALA conversion rates (provided there is vitamin b12 supplementation of course). This isn't a controversial view.
The most optimal diet following literally all the national health institution guidelines and that of the WHO will contain wild caught fatty fish once or twice a week and some moderate amounts of eggs, dairy and white meat.
@Raoul
See last 2 paragraphs. No it isn't "the healthier option", that's why the nutritional guidelines don't support it. Any study comparing vegans vs omnivores isn't taking into account one group has done a dietary intervention and the other hasn't. Correlation =/= causation.
