When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which

two ways are energy sources conserved when people run?

Heat energy is released from the body to the surroundings.

Chemical energy is converted to mechanical energy that's used for muscle movements.

The two ways by which energy are conserved when people run are: (1). Heat energy is released from the body to the surroundings. and (2). Chemical energy is converted to mechanical energy that is used for the muscle movement.

Explanation:

When people run, their body temperature increase and the body get hotter than normal. The homeostatic regulation comes into play and make the body to sweat so that it can cool down. The body release energy into the environment through sweating. So also, when one is running, the muscles are converting chemical energy in the body to mechanical energy and they are using the energy to do the work of moving the muscles.
