I. Title – The Effect of Volume on Heart Rate II. Problem/Research question – Your heart rate can be affected and changed using a variety of things. One thing that can cause your heart rate to change is the volume of audio. How does the volume of an audio track affect your heart rate? If the volume of an audio track is increased‚ the number of hearts beats per minute will increase as well. III. Variables – ❖ Independent Variable ➢ The volume of the audio track ❖ Dependent

Walking‚ Skipping‚ and Running on the Heart Rate Due Date: Friday‚ November 23rd‚ 2012 Question: What is the effect of walking‚ skipping‚ and running on a person’s heart rate? Hypothesis: If the intensity of the action increases (walking<skipping<running)‚ then the heart rate will also increase because the faster the legs are moving‚ the faster the leg muscles need to contract. When the leg muscles contract faster‚ more energy is used‚ and the heart will pump faster to deliver oxygen

the 10-12 year old subject’s heart rate read 83 beats per minute (bpm). After doing jumping jacks the 10-12 year old subject’s heart rate read 96 bpm‚ that is a difference of 13 bpm. Before doing jogging‚ the 10-12 year old subject’s heart rate read 82 bpm. But after doing jogging for two minutes‚ the 10-12 year old subject’s heart rate read 92 bpm‚ that is a difference of 10 bpm. As it is shown in my data table‚ before doing sit-ups the 10-12 year old subject’s heart rate read 72 bpm. After doing sit-ups

Question: How does the number of sit-ups affect your heart rate. Independent Variable (IV): Number of sit-ups ( 0‚5‚10‚15‚20). I chose these 5 increments because they are consistent numbers in which everyone can participate without it being to much. Dependent Variable: heart rate( BPM) +/- 4 ( number of beats in 15 seconds multiplied by 4). Materials: timer‚ flat surface‚ movable clothing Background: In this experiment I will test your heart rate and if it increases or decreases with exercise (sit-ups)

IntroductionThe purpose of this experiment is to determine whether or not caffeine has an affect on the heart rate of DaphniaHypothesisThe Daphnia heart rate will increase with the concentration of caffeine. I based my hypothesis on the fact that humans heart rates increase with caffeine as it acts as a stimulant drug. In the experiment there will be several variables that I need to try and control‚ the temperature of the water is one of these because if the temperature is higher or lower on the

Exercise affects all people differently‚ specifically a person’s heart rate and blood pressure. After exercising your heart rate should increase and your blood pressure should decrease (Blood Pressure Association‚ 2008). The purpose of this lab was to determine which level of exercise would have the greatest impact on affected pulse and blood pressure. In this lab we tested how exercise affected heart rate by testing a random group of people with different body types and exercise levels to see how

A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in the Journal

Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

example of a heart rate is called resting heart rate. The resting heart rate of the body is the number of contractions of the heart that occur in a single minute while the body is at complete rest. The resting heart rate can differentiate upon age‚ gender‚ and health of a human. There will also be a difference in number upon the resting heart rate of athletes and a non-athletes. I calculated 68 beats per minute for my resting heart rate. Another example of heart rate is target heart rate. Mathematically
