Experiment 1Heart beat and blood pressure lab reportIntroduction:In this experiment we will discuss the elevation rate of blood pressure and heart beat by doing two repeated challenges. First challenge would be that three different people, the first would be at rest, second will do exercise for at least 5 minutes and the third will walk for 5 minutes. Than we will check their blood pressure and heart beat after first task. After 20 minutes the challenge will be done again. Now let’s start the experiment.Objective:The purpose of this experiment is to check three different people heart beat and blood pressure while doing rest, exercise and walk for 5 minutes.Hypothesis:The heart beat and blood pressure will rise after doing this challenge.Materials:StopwatchTrackPulse checker3 adultsExperimental design:The dependent factor would be the heart rate and blood pressure.
The independent factor would be the Actions that will be performed.The control factor will be the adult and the time.Procedure:Measure the heart rate and blood pressure of all the three adults in resting positionsNote the dataOne person would be at rest, other two adults would do exercise of jumping rope for 5 minutesMeasure the heart rate and blood pressure of those two adultsNote the dataAfter resting for 20 minutesNext they have to walk for 5 minutes One would be in resting positionThan measure the heart rate and blood pressure of the two adults walkingNote the dataAfter resting for twenty minutes again start the second challenge with all above mentioned process. Quantitative analysis:Measured data of heart beat for first challenge:No. of series Heart rate in restbpm Heart after exercisebpm Time1 60bpm 60bpm rest2 75bpm 110bpm 5 minutes3 70bpm 105bpm 5 minutesMeasured data of blood pressure for first challenge:No. of series Blood pressure in restSBP/DBP Blood pressure after exerciseSBP/DBP Time1 119SBP79DBP 119SBP79DBP rest2 122SBP83DBP 138SBP90DBP 5 minutes3 117SBP80DBP 145SBP94DBP 5 minutesResults:The results of first challenge are as expected. Our hypothesis is correct due to exercise the heart rate and the blood pressure increases. Now after resting for twenty minutes we would repeat the above process again.
Measured data of heart beat after five minute walk, second challenge.No. of series Heart rate in restbpm Heart rate after walkbpm Time1 64bpm 64bpm Rest2 68bpm 104bpm 5 minutes3 60bpm 110bpm 5 minutesMeasured data of blood pressure after walk:No. of series Blood pressure in restSBP/DBP Blood pressure after walkSBP/DBP Time1 124SBP80DBP 124SBP80DBP Rest2 120SBP78DBP 140SBP95DBP 5 minutes3 115SBP75DBP 135SBP92DBP 5 minutesResults:After second challenge the result proved the hypothesis as above.
The heart rate and blood pressure increases due to walk off five minutes.Recovery curve for the difference and similarities between first and second challenge:First Challenge in rest: First Challenge after exercise: Second challenge in Rest : Second Challenge after exercise
