Evaluation of physical efficiency by pulse count after submaximal exercise

Abstract

The paper gives the results of investigation conducted in the Defence Science Laboratory to test the consistency, repetitive and discriminatory value of the D.S.L. E.T. Scores as compared to the pulse counts for one minute, taken 1/2'after 'Baithak' exercise at 40 cycles per minute extending over 3/4' to 2'. The duration of exercise decreases as the age increases. The results show that the variation of the simple pulse counts is considerably smaller than that of the D.S.L. Scores. In view of this finding it has been suggested that the Armed Forces may be classified for physical efficiency on the basis of pulse counts taken after 'Baithak' exercise. The classification suggested consists office grades of pulse counts. These are 80-90, 91-100, 101-110, 111-120 and greater than 120. The classification is done after adjusting the pulse count to 2' exercise. The adjustment works out to be 5 beats per minute for every 15 seconds decrease in the exercise.
