![]() Remember the intense staining indicates a high capacity for anaerobic capacity. Of the three highlighted cells on the screen, which have the potential to be more oxidative? 1 and 2 Of the three highlighted cells on the screen, which have the potential to be glycolytic? ![]() These cells were stained for mATPase, darker staining indicates a higher capacity to use ATP to contract muscles more quickly! 2 and 3 Since the enzyme succinate dehydrogenase is found in the mitochondria, the cells appear spotted or speckled. Once the average velocity over multiple heartbeats is know (cm/sec), what other parameter is required to calculate the cardiac output (cm^3*sec^-1)? The cross-sectional area of the aorta (cm^2) What is the correct systolic/diastolic blood pressure of the patient? 110/70 How did the heart rate change in patient A? About 2x How much did the stroke volume change in patient A? About 2x How much did the cardiac output change in patient A? About 4x Given that cardiac output did not increase as much as the oxygen consumption rate (which increased 8x), what is the most likely mechanism that could allow increased oxygen delivery by the cardiovascular system? An increase in the amount of oxygen removed from hemoglobin How did diastolic pressure change in patient A? There was little change What is the most likely explanation for such a low increase in the mean arterial pressure compared to the cardiac output? Vasodiliation reduces the resistance to blood flow What is the ratio of TPR at rest and TPR at 125 watts? About 3, TPR is higher at rest than during exercise How did the measured cardiac variables differ in subject E from the other individuals? Higher heart rate, lower stroke, lower diastolic and higher systolic pressure Which of the issues below aligns with the data from subject E? The aortic valve is failing to close, so blood flows back into the left ventricle Of the three highlighted cells on the screen, which are considered fast? Mike's blood lactate increased What does the power output measured during the Wingate sprint indicate? Anaerobic capacity With which response can the acute physiological effects of a Wingate sprint be associated? fight-or-flight Looking at the data, what is the most striking difference between Mike's first and last session? A higher peak power How much does the O2 consumption increase with exercise intensity before it plateaus? 8x What is the measurement of the velocity of moving particles the Doppler effect is based on? A shift in the frequency of the sound Thanks to the Doppler effect we can calculate the velocity at which blood is moving through the aorta.
