Exercise Physiology | Variation of Fuel Source with Exercise Intensity

The video explores how fuel selection changes with exercise intensity, focusing on the shift in energy source contribution from fat to carbohydrates as intensity increases. It explains absolute and relative energy expenditure, highlighting that higher exercise intensities require more energy, primarily from carbohydrates due to their efficient metabolism. The video concludes with a summary of these concepts, preparing viewers for a follow-up discussion on fuel selection variation with exercise duration.
