Starting the new season off with a basic question.

What is the relationship between aerobic heart rate and work output as fitness improves? My AeT heart rate seems reasonable, but I know my work output is pretty low. My hill climbing time (and running speed) is pretty bad.

Will the AeT HR stay the same, but the work output improve?
I could see the HR actually dropping if heart stroke volume and blood volume increase or the movement becomes more efficient. However, I could also see the HR increasing too if muscles require more oxygen and energy.

Does AeT HR actually tell you anything about fitness?

Much appreciation for your insights.

Hi chris,

It is difficult to answer the question because it would need more information about you to more correctly do it. In resume, as your training ramps up , your aET tends to be higher, closer to the Ant , your work capacity at a aerobic level is bigger. Having a good aerobic capacity its not enough to produce work , your local muscular endurance needs to be good.

Cheers,

Pedro
