Google "aspergers low muscle tone" or in my case "NVLD low muscle tone." It apparently was part of the early diagnostic criteria, before Aspergers really got formulated. So there might be some correlation, it's really hard to say.
In my case, I was kinda lucky and had reasonably strong leg muscles, but had/have crappy arm and upper body strength, and in general just twig arms. Oddly, the way my body is, my wrists and hands are really small, but then I have thick ankles and huge calf muscles. It's like a weird mix of ectomorph on top, and then endomorph on bottom. As far as now, it's like, so odd, as that mix allows me to parallel squat and deadlift a ton without much effort, but then I struggle at like 135 on the benchpress. As far as lack of athletic prowess as a kid, it was just sorta being a "late bloomer" which as your other thread asked, there's lots of variance going on with that. One guy I suspect with ASD or similar kinda...thing, as I said in your other thread, was 5'2 and 120 pounds when he got out of high school, and then 5 year class reunion, was 6' and 240 pounds. Talk about late bloomer...

As far as how it should affect you, well, there's lots of variables besides Aspergers in the athletic game. Genetics has a lot to do with it, different ethnicities do better at different things, and everyone has different body types they're just sorta stuck with whether they like them or not. My Indian friend is 130 pounds, and he wants to gain 20 pounds, whereas me I'm 195 at the same height and I wanna lose 20 pounds. He can do way more pullups than me (I can do none, woohoo), I can squat and deadlift way more than him. We just gotta work with what God gives us, and do the best we can.
