Developing Fitness Lab By: Megan McLin Purpose: Working out a technique to find for fitness without a strenuous activity Methods and Materials Per group: * An ECG rate * A laptop with the proper software for recording heart rates * A low chair or stool * A timer * A calculator In developing a fitness test, the hypothesis conducted in this experiment will test if ones heart rate will recover more quickly after exercise in fit people than in less fit people. Before starting the experiment, the person in the group exercising this experiment must determine their resting heart rate. If the resting rate is higher than 75 bpm, the person exercising in the experiment must not continue. To find the resting heart rate, locate the radial artery pulse on the wrist and record the number of beats within 12seconds with a timer. Then divide that time by 12 and multiply by 60. After the resting heart rate is completed, exercise by using a stepping stool or low chair. While exercising, determine how long to exercise to increase the heart rate by 1.7 X the resting rate and rest 5 minutes between exercise bouts. After completing the exercise, attach electrodes tot the recording ECG as soon as possible after exercise and record for 4 minutes. Determine BPM for first 30 seconds in minute 1 of recovery, first 30 second. Every group calculating should have one way to calculate so that the testing can be compared. Results The results show each group’s recording of heart rates within 4 minutes.
