Here is the question and all answer choices presented for analysis.
Question: Application-Level Multiple-Choice Items
How can endurance athletes best postpone fatigue during their activity?
Answer choices:
- ​Eat glucose periodically during the event.
- Fat load one to three days before the event.
- Avoid sports drinks during exercise.
- Stay in the moderate intensity range to prevent anaerobic metabolism.
- Eat glucose periodically during the event.
- Restrict fat to less than 20 percent of calories.

Now, let's evaluate each option in turn:
Option 1: Fat load one to three days before the event.
This strategy is not supported as a general best practice for postponing fatigue in endurance activities. Carbohydrate loading is the common approach for maximizing glycogen stores, not a focus on dietary fat loading. Excessive fat loading does not reliably delay fatigue and can impair performance due to gastrointestinal distress or decreased exercise economy. Therefore, this option is unlikely to be effective as a universal endurance strategy.
Option 2: Avoid sports drinks during exercise.
Avoiding sports drinks contradicts widely accepted endurance nutrition guidelines. During long events, fueling with carbohydrates and electrolytes helps maintain blood glucose and fluid balance, delaying fatigue. Choosing to avoid sports drinks would risk early energy depletion and dehydration, making this choice incorrect for postponing fatigue.
Option 3: Stay in the moderate intensity range to prevent anaerobic metabolism.
Staying strictly in a moderate intensity zone can help with overall endurance, but it does not fully address delaying fatigue throughout an event, especially as glycogen stores deplete. Endurance athletes often benefit from pacing strategies that mix intensities, including some higher-intensity segments, to optimize performance. This statement is overly simplistic and not universally correct as a primary fatigue-delay strategy.
Option 4: Eat glucose periodically during the event.
This option aligns with established endurance nutrition practices: providing a steady supply of carbohydrates (glucose) during exercise helps maintain blood glucose levels, preserves muscle glycogen, and can delay the onset of fatigue, particularly in events lasting beyond 60–90 minutes. It directly targets energy availability during activity, making it a sound and evidence-based approach.
Option 5: Restrict fat to less than 20 percent of calories.
While fat intake is important, restricting fat to a very low percentage does not directly address fatigue postponement during endurance events in the short term.Fat oxidation remains a factor, but the primary fatigue-delaying strategy during events is carbohydrate availability and hydration, not a strict macronutrient percentage restriction. This option is not the optimal method for postponing fatigue during activity.

In summary, among the listed options, the recommendation that best supports postponing fatigue during endurance activity is to provide a carbohydrate source—specifically, eat glucose periodically during the event. The other choices either misrepresent best practices (fat loading, avoiding sports drinks, overly simplistic pacing without carbohydrates) or minimize the practical impact of key nutrients (fat restriction) on fatigue delay.
