The world record in the 100-meter dash in 1924 was 10.4 seconds, while in 1948, (the first use of starting blocks) was 10.2 seconds, and was 10.1 seconds in 1956. The constant drive for faster athletes with better technology has brought man from 10.4 seconds to 9.58 seconds in less than 100 years.
Biomechanics of sprint running. Sprinters during a 200 m race. Sprinting involves a quick acceleration phase followed by a velocity maintenance phase. During the initial stage of sprinting, the runners have their upper body tilted forward in order to direct ground reaction forces more horizontally. As they reach their maximum velocity, the ...
Persistence hunting. Persistence hunting, also known as endurance hunting or long-distance hunting, is a variant of pursuit predation in which a predator will bring down a prey item via indirect means, such as exhaustion, heat illness or injury. [ 1][ 2] Hunters of this type will typically display adaptions for distance running, such as longer ...
The test requires participants to run 20 meters back and forth across a marked track keeping time with beeps. Every minute or so, the next level commences: the time between beeps gets shorter; participants must run faster. If a participant fails to reach the relevant marker in time, they are cautioned. A second caution ends the test for that ...
Man versus Horse Marathon. The Man versus Horse Marathon is an annual race over 22 miles (35 km), where runners compete against riders on horseback through a mix of road, trail and mountainous terrain. [ 1][ 2] The race, which is a shorter distance than an official marathon road race, takes place in the Welsh town of Llanwrtyd Wells every June.
The preferred transition speed (PTS) is the speed at which an organism typically changes from one gait to another. Humans spontaneously switch from a walk to a run as speed increases. In humans, the preferred transition speed from walking to running typically occurs around 2.0 m/s (7.2 km/h; 4.5 mph), although slight differences have been shown ...
With millions of people living in the U.S.A., it’s often challenging to find a school friend you are no longer in touch with or a family member whose contact information you lost years ago. For ...
Endurance running hypothesis. The endurance running hypothesis is a series of conjectures which presume humans evolved anatomical and physiological adaptations to run long distances [ 1][ 2][ 3] and, more strongly, that "running is the only known behavior that would account for the different body plans in Homo as opposed to apes or ...
