3
The 'window of opportunity' for anabolic response following resistance exercise is largely influenced by: Which of the following statements is most accurate regarding the timing of post-exercise nutrient intake?

C
Consuming protein within 30-60 minutes post-exercise is essential to maximize muscle protein synthesis rates.
