Metabolism

Metabolism Chart

The metabolism chart estimates the reliance on fat and carbohydrates for energy based on exercise intensity.

Human 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 zone marked in yellow, which includes the FATMAX point if indicated, you can train effectively for your goals.

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

• TSS: The Training Stress Score (TSS) achievable during the training session if maintaining the power at the FATMAX level for the specified duration.
