Long-term training lowers resting IL-6 levels due to which factor?

Long-term training lowers resting IL-6 levels due to which factor?

• A. Higher glycogen content
• B. Increased glycogen synthesis
• C. Unchanged glycogen content
• D. Lower glycogen content

Answer: (D)

Long-term training reduces resting IL-6 as part of the overall shift toward a less inflammatory, more metabolically efficient state. One way this shows up is through energy substrate balance at rest. With chronic training, the body becomes better at using fat as a fuel and relies less on stored glycogen as a resting energy source. This lower resting glycogen content is associated with reduced basal inflammatory signaling, so resting levels of IL-6 decline. Higher glycogen content, unchanged glycogen, or increased glycogen synthesis at rest don’t align with this anti-inflammatory adaptation. They wouldn’t explain a drop in resting IL-6 the way a shift to lower resting glycogen does, given the broader metabolic improvements that come with long-term training.
