Question 1

Which form of omega-3 fatty acid found primarily in fatty fish has the most direct anti-inflammatory benefit for exercising muscles?

Accepted Answer

EPA and DHA

Answer

EPA and DHA from marine sources are long-chain omega-3s that directly reduce exercise-induced inflammation and may support muscle protein synthesis.

Question 2

What is the primary advantage of chocolate milk as a post-workout recovery beverage?

Accepted Answer

It provides an ideal 3:1 or 4:1 carbohydrate-to-protein ratio for glycogen replenishment and muscle repair

Answer

Chocolate milk naturally provides carbohydrates and protein in a ratio shown to support glycogen resynthesis and muscle protein synthesis after exercise.

Question 3

Caffeine improves exercise performance primarily through which mechanism?

Accepted Answer

Blocking adenosine receptors to reduce perception of fatigue

Answer

Caffeine competitively blocks adenosine receptors in the brain, reducing the perception of effort and fatigue during exercise.

Question 4

For a person trying to lose weight, which statement about exercise and appetite is most supported by research?

Accepted Answer

High-intensity exercise may temporarily suppress appetite, but compensation eating often offsets calories burned

Answer

Research shows that many people unconsciously compensate for exercise calories through increased food intake or reduced non-exercise activity, blunting expected weight loss.

Question 5

Which nutrient timing strategy has been shown to support muscle protein synthesis throughout the day?

Accepted Answer

Distributing 20–40 g of protein evenly across 3–5 meals throughout the day

Answer

Distributing protein intake evenly across meals maximizes muscle protein synthesis signaling because each serving stimulates anabolic pathways that a single large dose cannot sustain all day.
