Final answer:
To control the dominant metabolic pathway during interval training, you can adjust the rest intervals, decrease the intensity of high-intensity intervals, and change the order of intervals in a session.
Step-by-step explanation:
The dominant metabolic pathway during interval training can be controlled by adjusting the rest intervals between high-intensity intervals. By increasing the rest intervals, the body has more time to recover and the aerobic pathway becomes dominant. Decreasing the intensity of high-intensity intervals can also shift the dominant pathway towards aerobic metabolism. Additionally, changing the order of intervals in a session can impact the metabolic pathway that is conditioned.
