Standardizing rest period between iterations according to the heart rate (140 / s) to develop special speed endure of running 800 meters for youth.

Abstract

The importance of research to conduct a study to standardizing a period of rest between repetitions to develop special speed endure by heart rate on three totals (140/s), The problem with research standardizing rest period between iterations to be 140/s for development the ability of a physical task, speed endure at which require such rationing, because the use of this rate of the heart rate is difficult to use in the training and knowledge of the impact positive or negative, The duration of the heart rate of 140 / s make adaptation more Whenever shorten the duration of the rest period and increases the pressure on the efficiency of physiological and physiology and organic muscle, Adoption of the heart rate 140/s rest period between repetitions in games that require the intensity in performance
