Resting and use cardiac cycle length -a. What was the comely resting cardiac cycle length? 831 b. What was the mean(a) physical exercise cardiac cycle length? 434 c. The kitchen range of figure resting cardiac cycle length is amid 818 and 858 ms. Did average cardiac cycle length increase, decrease, or non channel with exercise? Decrease2. Resting and utilisation EDV -a. What was the average resting EDV? 139 b. What was the average use EDV? 140 c. The range of dominion resting EDVis in the midst of 135 and 145 ml for these subjects. Did average EDV increase, decrease, or not alternate with exercise? not convince3. Resting and exercising ESV -a. What was the average resting ESV? 70 b. What was the average exercising ESV? 36 c. The range of convention resting ESV is between 65 and 75 for these subjects. Did average ESV increase, decrease, or not spay with exercise? decreaseTable 3 Resting and Exercising HR, SV and COHR ( cuts per second) 70 74 72 72 Resting Values SV (mL) SV (L) 73 70 63 0.073 0.07 0.063 0.069 CO 5.1 5.2 4.5 4.9 HR (strokes per second) 139 131 145 138 Exercising Values SV (mL) SV ( L) one hundred five 103 105 0.105 0.103 0.105 0.104 CO 14.6 13.5 15.2 14Subject 1 Subject 2 Subject 3 AveragesResting and Exercising SV and CO4. Resting and exercising HR a. What was the average resting HR? 72 b. What was the average exercising HR? 138 c. The range of typical resting HR is between 70 and 73 beats per sharp for these subjects. Did average HR increase, decrease, or not change with exercise? increase5. Resting and exercising SV -a. What was the average resting SV? 69 b. What was the average exercising SV? 104 c. The range of formula resting SV is between 60 and 80 ml for these subjects. Did average SV increase, decrease, or not change with exercise? Increase6. Resting and exercising CO a. What was the average resting CO? 4.9 b. What was the average exercising CO? 14 c. The range of everyday resting CO is between 4.2 L per minute and 5.84 L for these subjects. Did average CO increase, decrease, or not change with exercise? increaseDiscussion1. What caused the cha nge in HR with exercise? Muscles use more than group O andglucose from the root with increase movement. This produces wastes that decrease rent pH below the normal range causing an increase in stock ticker lay. The soreness rate increase delivers blood to the lungs and kidneys more quickly so these organs can remove the wastes from the dust. The faster the muscles use energy and create waste, the faster the magnetic core must pump blood.2. Discuss the fix of venous return and heart rate on exercise EDV. Exercise increases venous return by forcing your remains to institute and enlarge blood vessels. In growth to circulatory improvements, exercise helps muscles and tissues become t from each one to allow them to overcome the stresses of working out. During exercise, the be demands additional oxygen and requires removal of redundant carbon dioxide increasing the heart rate. EDV is increased with exercise 3. What caused the change in ESV pot with exercise? ESV decreases with exercising so that thither is less resistance for the blood to escape to increase cardiac production signal. 4. Why did SV change with exercise? SV increase during exercise because an individuals body needs more oxygen and provisions that are both received from the pumping of blood.The level of increase of SV is also depends on the subject of exercise 5. Discuss the importance of the change in CO with exercise? When the body is in rest cardiac output is lower as the demand in oxygen is low. During exercise heart rate and stroke quite a little increase which results in an increase in cardiac output 6. Restate your predictions that were patch up and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving accompaniment data from your experiment that supports your corrections. My prediction were correctApplication1. We measured the stroke volume of the remaining ventricle. What was the average stroke volum e of the practiced ventricle at rest and after exercise? 69 resting 104 exercising 2. Assume that for one beat, the stroke volume of the left ventricle is greater than that of the right ventricle. Explain why in a normal heart this would be rectify on the next beat. blood would be transferred from your systemic circulation into you pneumonic circulation.Pressures throughout your pneumonic circulation would begin increasing. As soon as small amount of blood is transferred from the systemic to pulmonary circulation, the pressure in the pulmonary veins and left atrium increases alittle. This increases the filling of the left ventricle, and the resulting increase in its end-diastolic volume increases the stroke volume, correcting the problem 3. Explain why selected athletes have a lower than normal heart rate, yet have a higher than normal ability to increase cardiac output. An athlete has a large stroke volume, which means a greater volume of oxygen is delivered to the body per h eartbeat.They normally have larger heart that results in higher cardiac output, as more blood is pumped out with each beat. The raised cardiac output allows the heart to beat more slowly
