Speed as the capacity of an individual to perform successive movement of the same pattern at a fast time. Speed is the product of genetic & environment factors. Genetic factors set limit of speed but environmental factors are also play a vital role. In fact following mentioned methods are usually adopted for the development of speed & these method help to training many organic system & motor components.
Pace run :- Pace run means running the whole distance with a constant speed. Generally 800mt and above races are included in pace races. An athlete can run a distance of 300m. at full speed but in longer races such a 800mtr. Or above, he must conserve his energy by reducing the speed. Ex-If there is a runner of 800m race. His best time is 1 minute 40 seconds. So he should run first 400 m in 49 seconds and next 400m in 51 seconds. This procedure is called pace race or pace run.
Acceleration Run - Acceleration run are usually used to develop speed indirectly by improving explosive strength, technique, flexibility and movement frequency. It is the ability of a sprinter to achieve high speed from a stationary position. For direct improvement of acceleration speed a sprinter should do 25-30 mt. sprint of 6-12 times. The maximum speed should be achieved within 5-6 sec. sufficient intervals should be provided between the repetitions..
