When you are exercising, your muscles use
that glycogen as a source of fuel.
Not exact matches
«Sooner or later the body runs out
of its preferred
fuel source,
glycogen, and starts to break down muscles and organs to use
as fuel — which is bad news,» says Dr Barclay.
When the body runs out
of glycogen as fuel, it turns to other
sources, such
as fat.
Our bodies generally draw upon a combination
of carbohydrates and fats to produce ATP, with the exception being very short - duration, high - intensity anaerobic activities, such
as a 100 - meter sprint where the primary
fuel sources are creatine phosphate, stored ATP, and muscle
glycogen (i.e., carbohydrates stored in the muscle).
As you check out the graph above, think of plasma glucose as something you'd get from a gel or sports drink or bar (or from the breakdown of protein); plasma free fatty acids as something you'd get from breaking down your own fat tissue, or from a dietary source of fat; muscle triglycerides as stored fat in muscle (or perhaps from an external source like coconut oil, if that's your fuel of choice), and muscle glycogen as your body's storage carbohydrat

as your body's storage carbohydrate.
This is because it uses fat
as one
of the main
fuel sources, whereas HIIT and weight training use mostly
glycogen (carbohydrates).
Many
of our metabolisms have been trained to run on dietary carbohydrate and
glycogen as their primary
fuel sources, making the first few hours to days
of fasting a challenge.
Once it depletes its
glycogen stores, the body burns fat
as its main
source of fuel as long
as insulin levels remain low.
While it is true that resistance training utilizes
glycogen as its main
fuel source [43], total caloric expenditure
of strength athletes is less than that
of mixed sport and endurance athletes.
Insulin lowers blood glucose levels partly by suppressing the release
of glucose from the liver, by increasing
glycogen (a kind
of starch) synthesis and storage, and by inhibiting
glycogen breakdown and the formation
of glucose from other
sources such
as glycerol (from fat), lactate (from the metabolism
of fuels like glucose and fructose by the liver and muscles) and amino acids (from proteins) by the process known
as gluconeogenesis.
