My personal feedback and experiment of the polar heart rate monitor.
🏋🏽♂️ Hard core exercise & short bout of cardio training
🩸Fuel utilization based on heart rate
As you can see on the top of the first photo that the fat burning rate was 35% mean mostly my body was burning 65% carbs as an energy source compared to burning fat.
Looking at the line graph of the first photo that when reaching to the green, yellow & red line (above 135bpm), the body presumably start burning more carbs. At the blue line and grey line (below 135bpm) will burn more fat.
🩸 Fuel utilization according to the exercise intensity
During exercise, the body’s energy utility is presumably Carbs (50%) & Fat (50%) but it will vary depends on the exercise intensity and duration what fuel will use more or less during exercise. During the higher intensity, the body use more percentage of Carbs as a primary energy source because when the intensity increases, the body need to get the energy quickly as the carbs can generate energy very quickly and the fat take so much time to produce energy.
The more intensity increases, the higher the chance of the carbs ratio will be used as a primary energy source, and vice versa with the Fat.
If you want to burn both Carbs & Fat during exercise, you should train at the moderate intensity and duration. You can calculate your moderate intensity heart rate zone 3 between 70-80% of HR max. Mine is around 132-151bpm.
🩸Fuel utilization with diet
When you eat more carbs than your body need during the day, you should put higher intensity exercise on your training programme accordingly and for the fat is the other way around.
You can adjust your diet based on how heavy you will train during the day or you can adjust the training based on how much you have eaten during the day.
