The Harvard Step Test was developedt in 1943 as a physical fitness test, and modifications of it remain in use today. The candidate steps up and down on a bench 20 inches high 30 times per minute for 5 minutes. The pulse is counted three separate times for 30 seconds each: at 1 minute, 2 minutes, and 3 minutes after the exercise is completed. If P is the sum of the three pulse counts, then the physical efficiency index E is calculated using 15,000 E= The following table shows how to interpret the results of the test. Interpretation Efficiency index Below 55 Poor condition 55 to 64 Low average High average Good Excellent 65 to 79 80 to 89 90 & above (a) Does the physical efficiency index increase or decrease with increasing values of P? O increase O decrease Explain in practical terms what this means.
