d. They can store more glycogen.
e. Glycogen breakdown occurs more slowly.

Which of the following is not a property of conditioned muscles? c. They rely less on glucose and more on fat breakdown for energy.

Explanation:

Muscle strength can improve a lot through high-resistance activity with a low number of repetitions. Conditioned muscles rely less on glucose and more on fat for energy, so glycogen breakdown and glucose use occur more slowly in trained individuals. This is how training affects glycogen use, making people more effective in the burning fat for energy.

Other thing to take into account is that the intensity of activity affects glycogen use. For example, moderate activities use glucose and fatty acids; by relying on fatty acids, glycogen is conserves (aerobic).
