How exercise can lower your heart rate
(Abstract – Summary)
Have you had a physical exam done by a doctor to determine whether you may have any heart or circulatory problems? If you’re clear of any medical issues it’s highly likely that you can lower your resting heart rate by improving the efficiency of your cardio vascular system. Cardio exercise 15 to 20 minutes a day three or more days a week is generally seen as a good basis. Walk, swim, bike or whatever you prefer but get that heart rate up into the 80% of max capacity range for 15-20 minutes and you’ll find yourself on your way to lowered resting heart rate and a whole lot of other benefits.
(Introduction)
We are doing this study to disprove that lack of exercise lowers resting heart rate and has been confirmed by consumer health magazines, medical science and sports medicine.
(Methodology)
We took a group of college students and placed them within two groups. Group #1 – physically fit persons and Group #2, non-physically fit persons. Class room instructor had students check their pulse at 30sec intervals before and after one-minute step arobic exercise and listed results on tables below:
The Essay on Affects of Physical Activity on the Heart Rate And Blood Pressure
Purpose: The lab prepared will teach you how to measure blood pressure. Learn where systolic and diastolic pressure begins. Next observe venous return, heart rate, and blood pressure in three different scenarios including: normal range, resting rate, and increased exercise. Research: In the circulatory system lab, students observed how physical activity affects blood pressure and heart rate. With ...

(Conclusion)
A delayed decrease in the heart rate of both groups during the first minute of exercise confirms that exercise lowers overall heart rate at resting levels.
