Homework Answers
The 20 week cardio vascular training program leads to following physiological changes:
- Reduction in heart rate. The normal heart rate is about 80 beats per minute. Heart rate becomes as low as 28-40 beats per minute in elite endurance athletes.
- Stroke volume increases as a result of exercise. In normal people stroke volume is about 50-70ml/beat which can increase up to 130ml/beat after exercise; i.e. about 40% increase .This is because the left ventricle contracts more forcefully during exercise.
- Increase in stroke volume further increases cardiac output.
- As a result of exercise, blood flow starts moving towards those tissues of the body, which are in greater need of oxygen. More blood flow towards skin occurs, which promotes heat loss.

Name two physiological changes that occur in the muscle due to exercise training which allow an individual to improve their fitness (VO2max)? Why do these changes result in a change in overall fitness? Does max HR change with training? Are there any cardiac adaptations to long-term exercise training?

List and describe the normal ECG changes that occur during the submaximal and maximal stages of a graded exercise test (GXT) (i.e. changes in wave amplitudes, interval durations, etc). Describe why the physiological reason(s) that these changes occur (for example: R-R interval decreases dramatically during exercise. This occurs because heart rate increases during exercise in order to increase cardiac output/blood flow to the working muscles).

1- Explain the changes in heart rate between conditions. Describe the physiological mechanisms causing these changes. 2- Are there differences in the cardiac cycle with the respiratory cycle (“Start of inhale-exhale” data)? 3- What changes occurred in the duration of systole and diastole between resting and post-exercise? 4- In the normal cardiac cycle, the atria contract before the ventricles. Where is this fact represented in the ECG? 5- What is meant by “AV delay” and what purpose does the delay serve?...
