Question

Before an endurance training program, a 20 year old college male had a cardiac output of 5.0 L min^-1, a resting heart rate of 60 beats min^-1, and a stroke volume of 83 mL beat^-1. After 16 weeks of endurance training his heart rate was now 50 beats min^-1 so his resting cardiac output would be Equal to heart rate divided by stroke volume. 4.2 L min^-1. Equal to cardiac output divided by stroke volume. 5.0 L min^-1. During interval training, the rest interval should be long enough to all rate to reach a level of:

Explanation / Answer

Resting cardiac output would be 4. 2L/min as CO=SV×HR

Cardiac output would be reduced as CO/SV
