Introduction
The purpose of this lab is to record the resting heart rate and blood pressure of the participant, then record the same two variables during submaximal exercise, in order to observe the effects exercise would have on these two health related measurements. Heart rate is the number of times a heart beats per minute (BPM) at either the radial or the carotid and should stay around 60-80 BPM. Males usually have higher heart rates than females due to size; it takes more force to send blood through a larger body. With exercise, the heart can be trained to beat at a lower rate as it enlarges and strengthens making the heart pump twice as much blood than an unfit individual. When it comes to age, the resting heart rate remains constant, …show more content…
It is measured in millimeters of mercury (mmHg) by using a sphygmomanometer and a stethoscope. It continuously changes throughout the day depending on positioning, diet, stress level, caffeine/alcohol intake, cigarettes, body temperature, and bladder fullness. The ideal blood pressure measurement should be 120/80 mmHg at rest. The first number, called the systolic pressure, signifies the pressure in the blood vessels when the heart contracts, and the second number, the diastolic pressure, signifies the pressure between beats. The diastolic changes slightly during exercise, but the systolic greatly increase because the heart works harder to pump out more blood. Submaximal graded exercise test is any physical activity where intensity increases at regular intervals up to, but never exceeding, 85 percent of an individual’s maximum heart rate. Testing the submaximal level is ideal because all subjects can participate in a safe …show more content…
