I don't see how the tone of the muscles can be to do with the wiring of the brain. Suppose it's another invented feature that is chosen to associate with Autism. My muscles are normal. A little weak, but I'm sure if I went to the gym I could build my muscles up if I wanted to. I've got a very strong back. Most people hurt their back when lifting heavy boxes and stuff, but I only hurt my arms only - never my back.
I may have low muscle tone in my lower face but it might be because I've got big teeth at the top front and might be the reason why I can't close my mouth when laying on my back.
Like someone else said, muscle tone can mean two different things. The first, most common definition, which is more of a slang definition, means firm muscles with a low percentage of body fat. The second, more technical definition is how finely a muscle is able to contract. Someone with fine muscle tone is more coordinated, and can do things like have nice hand writing, drawing skills, can catch etc. Someone with poor muscle tone moves in cruder, grosser movements, knocks things over, might be "clumsy" etc.
As far as putting on muscle, believe it or not, the weight/rep ratio (1-4 reps ) that produces the greatest strength gains actually produces minimal size gains. The best range to increase size is 8-12 reps, and it produces less strength gains. This would explain why some people are stronger than they look.
The reason being is that the nervous system affects a muscles strength and endurance more than most people realize. It could perhaps be the most important "body part" for any athlete to exercise. It controls the percentage of muscle fiber utilized in any given motion. People claim that a chimpanzee is like 6 times stronger than a human. It's actually more like 3 times. One reason is bone structure. The main reason is coordination and muscle tone. Their nervous system isn't as coordinated and they use most of their muscle fiber for everyday movements like picking something up, etc. For a human to utilize all of their muscle fiber, we usually need a fight or flight adrenaline rush. Which is why mothers can lift cars off of their children and stuff. Basically, as the percent of muscle fiber used increases, coordination decreases.
OK. Hope my two cents is insightful.
