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

Exercise and heart rate: The data in the table below represent the maximum benefit to the heart from exercising‚ if the heart rate is in the target heart rate zone. Age‚ x Maximum number of heart beats‚ y 20 140 30 133 40 126 50 119 60 112 70 105 a) Plot the data in the table above. What kind of pattern can you observe from your graph? b) What type of relationship appears to exist between the maximum number of heart beats and age? The maximum number of heart beats decreases

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

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

Does caffeine affect heart rate? Background Information: Caffeine is a bitter white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. A German chemist‚ Friedrich Ferdinand Runge‚ discovered it in 1819. Plants produce caffeine as an insecticide. It is found in varying quantities in the beans‚ leaves‚ and fruit of over 60 plants‚ where it acts as a natural pesticide that paralyses and kills certain insects feeding on the plants. Cocoa in South America‚ coffee in Africa

Investigating the effects of Caffeine on the heart rate of Daphnia Shrimp. Aim: In this experiment we are trying to find out how varying the concentration of caffeine can affect the heart rate of Daphnia shrimp. Prediction: I predict that caffeine will increase the heart rate of the shrimp . Introduction: I believe the results will comply with my prediction. Caffeine is a compound found in especially tea and coffee plants and acts as a natural pesticide. Caffeine is a central nervous system

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

| Gender Influence 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

“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

The heart is a vital organ in the human body. Though only the size of the fist‚ it pumps blood to the rest of the body by rhythmic expansion and relaxation. The frequency of this cardiac cycle is measured by the term heart rate. The heart rate is the number of contractions (beats) of the heart in a minute. The heart rate tends to increase with response to a wide variety of conditions like vigorous physical activity or according to our hypothesis‚ music. Music has an arousal effect which is related
