Pulse Rate Essay Example for Free

Pulse Rate EssayThe purpose of this practical is to investigate how the pulse position of humanity changes when they exercise. Someone who is physically fit can supply their muscles with enough blood, carrying glucose and oxygen, for an activity at a lower heart and breathing rate. The fitter you ar the lower your resting heart rate. You and your classmates will be the humans investigated.SAFETY If you know you have any condition that affects you doing exercise, please exonerate sure your teacher knows forward you start the investigation. In the investigation you are going to measure and record your pulse rate, before and after doing some physical activity. Work in pairs and decide who will be the gymnastic apparatus and who will be the pulse-taker and recorder. The pulse-taker takes the resting pulse of the gymnastic apparatus. The exerciser should be sitting down and holding their left hand come to the fore with their palm facing up and their elbow serial. The pulse-ta ker puts the index and middle fingers of their right (or left) hand together, and presses the pads of their fingers lightly on the under font of the exercisers left wrist, just at the base of their thumb. With their fingers in this position, they should be qualified to feel a pulse. Once the pulse has been found, the pulse-taker starts the stopwatch and counts the number of beats in 15 seconds. To have the heart rate in beats per minute, the pulse count for 15 seconds is multiplied by 4. The exerciser exercises (jog on the spot, do jumping jacks, step up and down on the platform at the social movement of the room at a rate of 30 steps per minute) for 3 minutes. The pulse-taker counts the number of beats in 15 seconds immediately after exercise has stop, then 2 minutes after exercise stopped and then 4, 6 and 8 minutes after exercise stopped. These rates should be taken with the exerciser sitting down. Recovery is to be assessed by calculating the 4 minutes after exercise harbor as a percentage of resting rates and comparing the percentage with the measure of fitness. This should give an inverse kindred i.e. the fitter the subject, the lower the percentage.LAB REPORTDateTopicAimQuestionMaterials and apparatusVariables* single-handed (changed)* Dependent (measured)* Controlled (held constant)Method numbered stepsObservations and results* Table neatly govern up, units in header column visit the title is descriptive. * Graph of data summarised in put over.* A concise description of other observations made, that are non given in table. * Calculation of the 4 minutes after exercise value as a percentage of resting rate.
