Submaximal cardiac output is ____________ in trained individuals when compared to untrained individuals.

Lower

None are correct

Higher

The same

What is preload as it relates to the cardiac cycle?

Preload is the amount of blood in the left ventricle after the filling phase of the cardiac cycle.

None of the choices are correct

Preload is the resistance to ejection that the heart faces during systole.

Preload is the amount of blood that is ejected from the heart during systole.

Answer #1

1. Submaximal cardiac output is ____________ in trained individuals when compared to untrained individuals.
   
     The same

  The submaximal cardiac output will be same in trained and untrained individuals .

2. What is preload as it relates to the cardiac cycle?

None of the choices are correct

The preload is the amount of sarcomere stretch experienced by the cardiac muscle cells during at the end of ventricular filling during diastole.

Select the MOST CORRECT answer. During the cardiac cycle... Blood flows from the right atrium, through the AV valve, and is pumped by the right ventricle into the pulmonary artery. The ventricular diastole occurs at the same time as atrial systole and atrial diastole. The second heart sound (S2, or dup) occurs just as the left ventricle reaches its highest pressure, which exceeds aortic pressure. Both a) and b) are correct and c) is incorrect. a), b) and c) are...
