Subjects are healthy males of similar age, height, and weight.
- CO will be determined in three healthy males at rest and after exercise.
- Ventricular EDV and ESV will be measured using MRI images.
- The length of one cardiac cycle will be measured from an ECG.
- HR will be calculated from the measured cardiac cycle lengths.
- SV will be calculated from the measured EDV and ESV.
- CO will be calculated from HR and SV.
- Compare resting and exercising HR, SV, and CO.
