D)Ketones

Quizplus · Accepted Answer

Training improves the muscles' ability to use fatty acids as a fuel source, which is known as "fat adaptation." This occurs due to an increase in the number and size of mitochondria within the muscle cells, which are responsible for producing energy from fatty acids. While glucose and amino acids can also be used as fuel sources, they do not require the same level of training adaptation as fatty acids. Ketones are not typically used as a primary fuel source for the muscles during exercise.
