Comparison of Various Kinds of Relaxation upon the Cardiac pulse after non-aerobic effect

. 8 20% 30% . / 7 . Trademile 16 / 12 . 20% 30%. Hr 8 20% 20% 30% 20%.The problem of the research is the ignorance of coaches and athletes to use the convenient rest from unairobic effort, either a rest recovery or relative rest recovery , and the intensity of the exercise recovery. The study aimed at discovering the values of the pulse rate as a field pointer during recovery period for 8 min., by using two kinds of recovery rest and exercise recovery with two experimental intensities 20% and 30%, and comparing these values with each other. To achieve these aims , the researcher chose a sample of 7 students from the second stage/ Physical Education Dep. The researcher exposed the sample to an unairobic test by running until being tired using the trademeal with a speed of 16 km.h and an incline of 12o . After the test , the pulse rate was measured for 8 mints in the recovery period for each min., and for three times, the first with a rest recovery, the second time with 20% of maximum intensity with recovery exercises, and third by 30% of maximum intensity with exercise recovery. The researcher concluded that there are differences in Hr recovery during the recovery period for 8 min., between the rest recovery and exercise recovery by 20% of intensity, and between exercise recovery 20%, 30% intensity.
