Unit II Lab Project

Introduction:

This lab focuses on three basic metabolic measures: pulse, respiration rate, and blood pressure. Metabolic refers to the complete set of chemical reactions that occur in living cells, allow cells to grow and reproduce, maintain their structures, and respond to their environments. The term pulse refers to the throbbing of the arteries that make a heart beat. A pulse can be taken from the neck, known as the carotid artery, the wrist, known as the radial artery, behind the knee, known as the popliteal artery, and on the inside of the elbow, known as the brachial artery. The term respiration rate refers to the number of breaths a person takes per minute.
Lastly, the term blood pressure refers to the force exerted by circulating blood on the walls of blood vessels. This term also usually refers to blood pressure in larger arteries, known as arterial blood pressure. This pressure is what circulates the blood through arteries, arterioles, capillaries, and veins. Systolic blood pressure is the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle. Diastolic pressure is the lowest pressure at the resting phase of the cardiac cycle.

Hypothesis:
I hypothesized that the “at-rest” metabolic rate will be lower than all the metabolic rates after activity. The three activities I chose was jogging on a treadmill, doing sit-ups on a weight bench, and lifting 10 lb weights. I hypothesized that jogging on a treadmill would give me the highest metabolic measurements, following lifting weights, then lastly doing sit-ups.

Materials and Methods:

This is where I did my “at-rest” metabolic rates

After I did sit-ups, I then recorded my metabolic rates.

After jogging on the treadmill, I then recorded my metabolic rates.

After lifting weights, I then recorded my metabolic rates.

This is the blood pressure machine I used, located in the Wal-Mart Pharmacy

This is me getting my blood pressure results

Analysis of my data:
Series 1 : Pulse ; Series 2 : Respiration rate ; Series 3 : Systolic blood pressure ; Series 4 : Diastolic blood pressure.
Series 1 : Pulse ; Series 2 : Respiration rate ; Series 3 : Systolic blood pressure ; Series 4 : Diastolic blood pressure.
My hypothesis was correct about the “at-rest” metabolic rate will be lower than all the metabolic rates after activity. I was also correct in hypothesizing that jogging on a treadmill would give me the highest metabolic measurements, following lifting weights, and lastly doing sit-ups.

Problems with data or technique:
One of the problems that could have occurred when recording my data, was doing all the trials one right after the other. This could have changed my pulse, and make it decrease because my body could be used to the activity after three times of doing it, and not have to work as hard.
Conclusion:
According to the data I found, harder activities such as running or jogging can increase your pulse and respiration rate, which can increase the strength of your heart, and make you at less risk for cardiovascular disease. Also according to the data I found, stationary activities such as sitting in a chair may be relaxing, but don’t challenge your body or keep it active, which keeps your immune system healthy, as well as prevents diseases and illnesses.
