Nonsense, strength is primarily a nervous system adaptation. Muscle volume increases at a faster rate than muscle cross sectional area so strength doesn't increase at the same rate as weight, your strength to weight ratio decreases and that means you're a slower athlete. That's part of the reason why p4p smaller guys are far stronger and faster than bigger guys. Like any athletic activity involving power it is primarily the nervous system and the properties of tendons that make the difference, muscle is important but it is only a small part of the picture of movement. Tendons recoil producing power and without them you'd barely be able to get off the ground.
