Fitness Improvement Based on Heart Rate Data

BY School of Tri

As you improve fitness, you will see your heart rate at a given speed (run) or power (bike) go down as your body becomes more efficient during aerobic exercise.

QUESTION

I have a HR monitor and my zones set up. How do I read the data to see if I’m improving?

ANSWER

As you improve fitness, you will see your heart rate at a given speed (run) or power (bike) go down as your body becomes more efficient during aerobic exercise.  Your heart, which is a muscle, becomes stronger and pumps more blood per beat. Your body also builds more capillaries to carry more blood and oxygen to working muscles while producing more aerobic enzymes to facilitate aerobic metabolic processes. As such, you may need to re-evaluate your heart rate training zones every 4-6 weeks as these changes occur, especially if you’re just starting out with exercise.
