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

How much alcohol do teens use? Alcohol is the most frequently used drug by teenagers in the United States. About half of junior high and senior high school students drink alcohol on a monthly basis‚ and 14% of teens have been intoxicated at least once in the past year.

the heart rate to slow and blood vessels to dilate‚ which then leads to blood pools in the lower body and less blood going up to the brain. c. Compensatory mechanism that become activated include; increase sympathetic outflow leading to arteriolar vasoconstriction‚ venoconstriction‚ and increase in heart rate; d. Increase pressure in the aortic arch will activate the aortic arch reflex and cause increased parasympathetic stimulation of the heart.

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)

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

The effect of exercise on heart rate Word Count THE EFFECT OF EXERCISE ON HEART RATE Abstract - Aims - This study is to ascertain‚ if there is an effect on heart rate after exercise. This is being done to see‚ if there is a difference between resting heart rate and heart rate after performing exercise. Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used‚ a polar heart rate monitor was used for each

designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals of intense exercise
