Embrace the Gray: Fat and Mitochondria in High Intensity Training
Effective training involves understanding that both high-intensity and moderate-intensity exercises contribute to fat burning and mitochondrial efficiency. Engaging in vigorous exercises (80-85% max heart rate) does not solely shift energy utilization to glucose; instead, it also enhances mitochondrial density, which in turn improves fat metabolism. While zone two training is beneficial for maximizing fat oxidation by maintaining a specific intensity threshold, high-intensity interval training is equally valuable as it fosters an increase in mitochondrial density, allowing for improved fat burning capabilities. Emphasizing a balanced approach enables more comprehensive fitness gains.
