I don't mean that dehydration doesn't lead to injuries, but that strain, as you mentioned, does.
The reason sprinters pull muscles is because, no matter how hard they train, it does not provide a real parallel to that extra gear that's needed in a race. Pushing just a little bit harder than before can do a lot of damage to a muscle.
