Introduction In this lab‚ I looked at how exercise affects a person’s heart rate (BPM)‚ systolic pressure‚ diastolic pressure‚ and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury. I found the MAP by the following equation‚ MAP= Diastolic Pressure + ⅓(Systolic-Diastolic). We found out that heart rate and systolic pressure were highest right after and during exercise‚ while diastolic pressure and

Tachycardia Condition The normality of the heart beats rate is of sixty to one hundred beats a minute at rest. A rate that is faster than 100 beats a minute in adults is called tachycardia. People experience transient heart beats‚ called sinus tachycardia‚ as a normal reaction to some type of excitement‚ anxiety‚ stress‚ or just exercise. There are two other types of tachycardia and those are named supraventricular tachycardia and ventricular tachycardia. The condition of tachycardia is caused

the base heart rate of each water flea. The base heart rate is the control in my experiment. The variables in the experiment are alcohol and caffeine. After finding the control of the first flea I will surround it with alcohol. The second flea will go through the same process as the first flea did‚ except the variable will be caffeine. The purpose of these two experiments is to see how surrounding one water flea with alcohol and another with caffeine affects each water flea’s heart rate. I believe

is the equation for Cellular Respiration‚ basically all this means is that it requires energy to create energy. So what the lab does‚ is determines how much energy it takes from person to person to exercise and how CO2 production‚ Breathing Rate‚ and Pulse Rate fluctuate. In America we are so concerned about looks and fitness‚ but if this is true than why is there such a problem with obesity. Well‚ if you read‚ and understand what has been done in this lab‚ than you will be able to adjust your metabolism

or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction An electrocardiogram can be used to record activity during the cardiac process of pumping and returning blood to the body and heart because of the electric current that spreads

of being so physical‚ your heart is forced to beat at extremely high rates. Studies conducted at the University of Florida under Dr. Augustine revealed more specific details. The heart rate spikes at the start of the moto‚ right as the gate drops‚ heart rates can reach over two hundred beats per minute at this time. After the start‚ the heart continues to beat at the same rate for the first few laps of the moto‚ then slows down to roughly one hundred seventy five beats per minute for the middle of

What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents

Injected Reagents on Frog Hearts Melissa Higdon Section 05‚ Group 01 November 19‚ 2013 Introduction: The heart is a very complex muscle for all species. It is responsible for sending oxygenated blood throughout the body as well as sending deoxygenated blood to the lungs‚ and continuously circulate this way for as long as we are alive. Many things can be effected‚ for example how fast the heart beats or how much force the heart chambers contract with

Differences Between Athletes’ Heart Rates And Non-Athletes’ Heart Rates By Using Step Test Introduction: Different people have different heart rates because of many reasons such as health condition‚ smoking‚ working out‚ among others. This step test is used to compare and figure out the differences between athletes’ heart rates and non-athletes’ heart rates before and after the test. Kuno Hottenrott stated that the normal average heart rate of people ranges from 40 to 100 beats per minute. However‚ the

First of all I will write a prediction on what I think the results may be and why. I will then state what equipment I will need to undertake both experiments. In a group of 3 we will record our results in table form and show the difference in a bar chart. These results will be for breathing and heart rate when we are resting for 1 minute‚ jumping for 1 minute and walking
