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.
Middle-distance running events are track races longer than sprints, ranging from 500 metres up to two miles (3218.688 metres). The standard middle distances are the 800 metres , 1500 metres and mile run , although the 3000 metres may also be classified as a middle-distance event. [ 1 ]
The 100 metres, or 100-meter dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the 100-meter (109.36 yd) dash is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and since 1928 for women.
sh – short track, including "indoors" but also allowing for outdoor 200 metres tracks w – mark of wind assistance . For events where wind assistance is a factor (outdoor races 200 metres or less, long jump and triple jump ), the wind reading is usually reported in metres per second (m/s).
Sprinting is a sport that requires development of footspeed.. Footspeed, or sprint speed, is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports, such as association football, Australian rules football, American football, track and field, field hockey, tennis, baseball, and basketball.
Running can assist people in losing weight, staying in shape and improving body composition. Research suggests that the person of average weight will burn approximately 100 calories per mile run. [61] Running increases one's metabolism, even after running; one will continue to burn an increased level of calories for a short time after the run. [62]
A distance medley relay is made up of a 1200-meter leg (three laps on a standard 400 meter track), a 400-meter leg (one lap), an 800-meter leg (two laps), and a 1600-meter leg (four laps) in that order. The total distance run is 4000 meters, or nearly 2.5 miles. Aside from the 400 meter segment, which is a sprint, all legs are a middle distance ...
The study showed that non-sprinters ran with an inefficient gait for the maximal speed trial while all groups ran with energetically efficient gaits for the distance trial. This indicates that the development of an economical distance running form is a natural process while sprinting is a learned technique that requires practice. [6]
