✍️ Sample NTP Questions & Answers
1. When reintroducing foods after an elimination diet, the recommended protocol is to:
Introducing one food at a time with a 3-day window allows delayed IgG reactions to manifest and clearly identifies specific triggers.
2. What is the primary purpose of the phosphocreatine (PCr) system during maximal sprinting?
Phosphocreatine donates its phosphate group to ADP to rapidly restore ATP, powering maximal efforts lasting roughly 1–10 seconds.
3. Which carbohydrate strategy best supports a 90-minute high-intensity soccer match?
Glycogen loading before and mixed glucose/fructose during a 90-minute match maximizes fuel availability and oxidation rates.
4. Which form of exercise has been shown to have the greatest benefit for improving insulin sensitivity and metabolic rate in overweight individuals?
Combining resistance training with aerobic exercise builds metabolically active muscle tissue and improves glucose uptake, yielding greater metabolic benefits than either alone.
5. Which sleep-related factor most directly contributes to weight gain when chronically disrupted?
Poor sleep suppresses growth hormone (which supports fat metabolism) and elevates ghrelin (the hunger hormone), promoting fat storage and increased appetite.
6. Which functional lab finding would prompt an NTP to investigate SIBO (small intestinal bacterial overgrowth)?
The lactulose breath test detects hydrogen and methane gas produced by bacteria in the small intestine, making it the primary non-invasive test for SIBO.
