144III.IDEA FROM:(COWl"INU£O)Simplified Pulse Ratio Test:(a) While sitting, have the student count and record her heartbeats forone minute.(b) Have the student face a chair (approximately 45 cm high) and step upwith the left foot, up with the right, down with the left, and downwith the right. The student should do 30 of these steps in one minute.In order to set the cadence the teacher or another student can callout "up, up, down, down" at the required speed or playa taped recordingof the cadence.(c) Immediately after completing the 30 steps, the student should sit,count and record her heartbeats for two minutes.(d) Have the student write her pulse ratio. Pulse Ratio = Heartbeats for2 minutes following the exercise : Heartbeats for 1 minute beforeexercise. Simplify theratio by dividing the firstnumber by the second, correctto one decimal place.

Three Minute Step Test:This test is administered likethe previous test, except thestudent steps for three minutes,and the cadence is 24 steps perminute. In addition wait oneminute after the student completesthe exercise and countthe heartbeats for only 30seconds. The efficiency scoreis the ratio ofnumber of seconds stepping x 100pulse for 30 seconds x 5.6Divide and check Table C to findthe physical fitness rating.*This table is accurate for juniorhigh girls. The efficiency scoresmay ne~d to be raised for juniorhigh boys. At the grade schoollevel there is not much differencebetween boys and girls.BelolN 2.'3 Above Aver9file2.'3 - 2..7Above 2.'1TABLE C*?hysicO-\Fi+ness'Ra..+lno72 -100 Excellent J[.t-f i Ciet"1c~Sc(")\'"eAvera.~eBelow AverQ!2,e62-7\ Very Good51-f,1 GoodAI-50 I="Q.. i r31-40 Poor0-30 Vey-l.j 'PoorPhysical Fitness Workbook, by Thomas Cureton.Copyright © 1944 by Stipes Publishing Company.Permission to use granted by Stipes Publishing Company(((
