What was the average resting cardiac cycle length? The average was 832 ms b. What was the average exercising cardiac cycle length? The average was 408 ms c. The range of normal resting cardiac cycle length is between 818 and 858 ms. Did average cardiac cycle length increase, decrease, or not change with exercise? The average cardiac length decreased by 424 ms 2. Resting and exercising EDP: Subject 1 – 142 ml at rest, 145 ml with exercise Subject 2 – 138 ml at rest, 141 ml with exercise Subject 3 – 144 ml at rest, 140 ml with exercise a. What was the average resting EDP? The average resting EDP – 141 ml b.

What was the average exercising EDP? The average exercising EDP – 142 ml b. The range of normal resting EDP is between 135 and 145 ml for these subjects. Did average EDP increase, decrease, or not change with exercise? The EDP increased slightly with subject 1 and 2 and decreased slightly with subject 3 3. Resting and exercising ESP..: Subject 1-74 ml at rest, 34 ml with exercise Subject 2-67 ml at rest, 35 ml with exercise Subject 3-68 ml at rest, 35 ml with exercise a. What was the average resting ESP..? The average resting ESP.. Is 70 ml b. What was the average exercising ESP..?

The average ESP.. With exercise is 35 ml c. The range of normal resting ESP.. Is between 65 and 75 for these subjects. Did average ESP.. Increase, decrease, or not change with exercise? The average decreased by 35 ml from resting to exercise See Table 3: Resting and Exercising HRS, SF, and CO See Graph: Resting and Exercising SF and CO 4. Resting and exercising HRS: Subject 1-70 BPML at rest, 156 BPML with exercise Subject 2-72 BPML at rest, 141 BPML with exercise Subject 3-74 BPML at rest, 145 BPML with exercise a. What was the average resting HRS? The average resting heart rate is 72 c.

What was the average exercising HRS? The average heart rate with exercise is 147 c. The range of normal resting HRS is between 70 and 73 beats per minute for these subjects. Did average HRS increase, decrease, or not change with exercise? The average heart rate a little more than doubled 5. Resting and exercising SF: Subject 1-68 ml at rest, 1 11 ml with exercise Subject 2-71 ml at rest, 106 ml with exercise Subject 3-76 ml at rest, 105 ml with exercise a. What was the average resting SF? The average SF is 72 at rest b. What was the average exercising SF? The average SF is 107 with exercise c.

The range of normal resting SF is between 60 and 80 ml for these subjects. Did average SF increase, decrease, or not change with exercise? The average SF increased with exercise by 35 ml 6. Resting and exercising CO: Subject 1-4. 8 ml at rest, 17. 3 ml with exercise Subject 2-5. 1 ml at rest, 14. 9 ml with exercise Subject 3- 5. 6 ml at rest, 15. 2 ml with exercise a. What was the average resting CO? The average at rest is 5. 1 ml b. What was the average exercising CO? The average is 15. 8 ml with exercise b. The range of normal resting CO is between 4. L per minute and 5. 84 L for these subjects.

Did average CO increase, decrease, or not change with exercise? The average CO increased with exercise by 10. 7 ml DISCUSSION 1. What caused the change in HRS with exercise? When we exercise the muscles are in a greater demand for oxygen, as well a need for release of carbon dioxide. The heart is responsible for this, by pumping the blood to the muscles faster when the demand is greater. 2. Discuss the effect of venous return and heart rate on exercise EDP. If we have a sufficient venous return (blood going into the heart) then the cardiac output ill be greater, the more the return the more the output.

Exercise demands more oxygen to the muscles, this demand calls for more oxygenated blood, thus the body increases heart rate, and the rest follow suit to supply the demand of oxygen. 3. What caused the change in ESP.. Volume with exercise? Consistent exercise will increase the ESP.., which will lower the resting heart rate. Reduced heart rate prolongs ventricular filling, thus increasing the EDP and ultimately allowing more blood to be ejected. 4. Why did SF change with exercise? The stroke volume is the amount of blood hat is pumped from the Left Ventricle to the body.

As I mentioned above the body’s demand for oxygen is increased therefore the stroke volume increases to meet that demand. 5. Discuss the importance of the change in CO with exercise? The Cardiac Output is the amount of blood that leaves the ventricles in a minute, the importance of this during exercise is the fact that the CO has the ability to change. The body needs more blood to circulate during exercise so the cardiac Output needs to increase to meet this demand. If the CO never changed we would not have sufficient oxygen to nourish our bodies needs.

And the amount of blood would be unbalanced leading to catastrophe in the Pulmonary circulation. 6. Restate your predictions that were correct, and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving supporting data from your experiment that supports your corrections. My predictions were all three correct: The HRS (Heart Rate) will increase, which it did in each subject and the increase was 70 to 156 BPML in subject one for example, which was over double. The two other subjects were 72 to 141 BPML, and 74 to 145 respectively.
