Metabolism

Metabolism Chart

The metabolism chart estimates your reliance on fat and carbohydrates for energy, depending on exercise intensity.

Humand use different energy sources depending on exercise intensity. At low intensity, fat is primarily utilized, while at higher intensity, carbohydrates become the main source.

• FATMAX: This is the point where fat oxidation (utilization) is most efficient. By maintaining power within the yellow zone (FATMAX), you can train effectively to reach your goals.

• Duration: The estimated time that you can sustain the power at the FATMAX point.

• TSS (Training Stress Score): The estimated training stress score achievable if power is maintained at the FATMAX level for the specified duration.
