Fat is a better fuel, but is organized in fat tissues and isn"t directly accessible to muscle, so signals must be sent to fat tissues to mobilize ffas. Already used 1/3 of glycogen and is using more and more fat to keep atp levels. She is changing gears as she is mobilizing more and more fat. Has to keep increasing the use of fat and not run out of glycogen if glycogen reserves are gone, there is remarkable reduction in running efficiency. Krebs has a weak point (the oaa) Small formation of oaa, but rapid utilization, thus oaa levels are usually low. This will slow down krebs unless you can support oaa.
