Question
During exercise of increasing intensity there is a greater reliance on muscle glycogenolysis due to local factors and increased levels of this hormone:Group of answer choicesadrenalineinsulinglucagon
Solution
The hormone that increases during exercise of increasing intensity, leading to a greater reliance on muscle glycogenolysis, is adrenaline.
Here's why:
-
During exercise, the body needs to produce more energy to meet the increased demand. This energy is produced by breaking down glycogen stored in the muscles, a process known as glycogenolysis.
-
As the intensity of the exercise increases, the body needs to produce energy more quickly. This is where adrenaline comes in.
-
Adrenaline is a hormone that is released in response to stress or excitement - such as during intense exercise. One of its roles is to stimulate glycogenolysis, helping to increase the rate at which energy is produced.
-
Therefore, during exercise of increasing intensity, there is a greater reliance on muscle glycogenolysis due to local factors and increased levels of adrenaline.
Insulin and glucagon are also involved in energy regulation, but they play a more significant role in maintaining blood sugar levels, rather than in the immediate energy production required during intense exercise.
