Determining the Effect of Arousal on the Heart Rate and Blood Pressure of Adolescent Males Wyatt Griffith and Michaela Rodriguez Wood River High School Hailey‚ ID 83333 ABSTRACT When male adolescents were unknowingly placed in an isolated environment with an attractive woman‚ there wasn’t enough viable data to determine whether or not their blood pressure increased. Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

The purpose of this practical is to investigate how the pulse rate of humans 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 are 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 make sure your teacher knows before you start

The Health of your Heart Introduction Keeping a healthy heart is vital for good health. This is because as cardiovascular fitness increases‚ so does the efficiency of the body. The heart becomes stronger and stronger every time you use it. Aerobic or cardiovascular fitness is measured by how efficient a person can pump oxygen to their working muscles to supply energy. It decreases the danger of getting life-threatening cardiovascular diseases. cardiovascular fitness is usually improved

Biology Task To investigate the effect of some factor affecting pulse rate Aim TO investigate how exercise affects the pulse rate. To do this‚ we took our normal pulse rate and then compared it with the pulse rate after exercise (walking). We kept all other factors constant so as to study the effect of exercise on pulse rate. Introduction Our heart is a muscle. It’s located a little to the left of the middle of our chest‚ and it’s about the size of our fist. There are lots of muscles all over

normally recognised as a drug to most. Caffeine has an effect on your heart rate‚ (this is how fact your hear beats) Caffeine is able to change the way your body and mind works Chocolate is known to have traces of caffeine in it also The aim What is the point this experiment;- My aim in this experiment is to see what effects caffeine is prone to on the heart rate‚ Also to compare someone’s heart rate who has consumed caffeine to someone’s who hasn’t. This should give us a

Part I: Pulse Rate Take your pulse at the wrist‚ as described on the Work Out tab of 4.02‚ and record it below. Your count for 30 seconds 30 x 2 = 60 bpm|Count again for 1 minute only = 84 bpm| Part II: Resting Heart Rate (RHR) a. Record your heart rate for an equivalent of a minute. b. Do not eat for two hours prior to taking your resting heart rate. c. Sit or lay down for at least 30 minutes before taking resting heart rate. d. An ideal time to take your resting pulse is immediately

Pulse rate is the number of times in a minute an artery pulsates or the rhythmic expansion and contraction‚ which indicates that a heartbeat has occurred. There are many factors which affect the pulse rate which includes: gender‚ age‚ body temperature‚ pain‚ emotion‚ exercise‚ blood pressure‚ consumption of stimulants‚ dehydration‚ body mass index (weight)‚ fitness level‚ lifestyle and many more. In my investigation‚ I would be examining the affect of gender in the change in the pulse rates‚ while

on Mean Pulse Rate | Laboratory Write-Up | Section 3 Kimberly Schmidt Section 3 Kimberly Schmidt | Savannah LeRette | 9/2/2012 | | Results In this experiment‚ we observed the effects that gender had on the mean pulse rate of men and women. Our goal was to support the prediction that stated‚ “If you are a female‚ then you will have a lower pulse rate.” The male subjects had an average pulse rate of 69 beats per minute before the step test. This was only 2 beats more than the

“How Pulse Rate is Affected By Lack of Sleep” By Southern Illinois Biology 200A Section 8 Ashley Hintz September 29‚ 2011 Results The purpose of this experiment was to find out if sleep affects your pulse rate. My hypothesis for this experiment was the people with less than six hours of sleep will have a higher pulse rate. I predicted that if sleep effects pulse rate then a person who has less than six hours of sleep will have a higher pulse rate. Both of which are supported in tables
