>more fast twitch >dominance in sprinting Sprinting is slow-twitch. Strength is fast-twitch... Slow-twitch = aerobic (running, sprinting, jogging, biking) Fast-twitch = anaerobic (strength, power, resistance) Also what the fuck does that have to do with niggers not being capable of swimming due to intelligence? If anything, more slow-twitch (aerobic) would make one better at swimming. e: I forgive you for being wrong though. It's a confusing naming system until you think about it. We're talking about the cellular level. Relative to size, running is slow as fuck. With weight lifting you need your muscles to activate at this fucking instant or you'll seriously injure yourself. With running a leg stride is quite a large period of time and the muscle isn't in active use for anything but a small fraction of the period.
