What is the maximum speed of man run? Scientists find biological men can run up to a maximum speed of 40 miles per hour (mph) or 64 kilometers per hour. This figure is much faster than the speed of 12 miles of the world's fastest sprinter Usain Bolt.
With the ability of 40 mph, a man capable of crossing the finish line 100 meters race during the 6.67 seconds, or the same time from Bolt to reach 60 meters. Bolt is the Olympic record holder for 100 meters for 9.58 seconds (41 steps).
Scientists calculate that the maximum speed by calculating the rate of speed of muscle in the body that are biologically able to move.
Previous studies have assumed a major barrier to the escape velocity as a member of the body can only take some power just when it slid to the ground. But new research suggests ototlah muscle contractions which holds an important key.
As reported by the Telegraph, Tuesday (26/1/2010), Dr Matthew Bundle, biomechanics expert from the University of Wyoming said the speed of muscle contraction speed allows people to run 35-40 miles per hour or even faster.
In the study researchers used a high-speed treadmill capable of recording speeds of 40 mph, and then measurements were taken at each step foot. This research has been published in the Journal of Applied Physiology.
Strength when jumping with one leg who applies exceed 30 percent if done by walking. Active force produced by the muscles of limbs approximately 1.5-2 times greater in one leg jump.
Dr Bundle and colleagues said their research shows running speed limit set by the limits of the muscle fibers themselves. Olympic gold medalist Usain Bolt could be close to 28 mph (44.8 km) in the 100-meter run. While the lion can run 50 mph when chasing prey and cheetah can reach a speed of 70 mph.
Professor Peter Weyand, a psychologist and researcher from Southern Methodist University in Dallas, said the notion that speed is limited by the force with limb movement to the surface of the foot is something that makes sense.
