If You Were to Jog 1 Km a Few Hours

Question

If you were to jog 1 km a few hours after lunch,which stored fuel would you probably tap?
A)muscle proteins
B)muscle and liver glycogen
C)fat stored in the liver
D)fat stored in adipose tissue
E)blood proteins

Accepted Answer

Jogging 1 km a few hours after lunch would require energy from stored fuel in the body. The body's immediate source of energy would be muscle and liver glycogen as they are readily available and easily broken down into glucose. Fat stored in the liver doesn't provide immediate energy for exercise, and fat stored in adipose tissue is a long-term energy source that is not efficiently used during short-term exercise. Blood proteins and muscle proteins are not sources of energy unless the body is undergoing extreme stress or starvation.
