Question 1

According to ACSM's position on protein, what daily protein intake range (g/kg) is recommended for athletes engaged in strength/power training?

Accepted Answer

1.6–2.2 g/kg

Answer

ACSM recommends 1.6–2.2 g/kg/day for strength and power athletes to support muscle protein synthesis and adaptation.

Question 2

A sports dietitian is counseling a female athlete who restricts caloric intake significantly. Which triad component does nutritional deficiency directly trigger first?

Accepted Answer

Low energy availability

Answer

Low energy availability is the initiating component of the Female Athlete Triad, which subsequently disrupts hormonal function and bone health.

Question 3

Which mineral is MOST likely to be deficient in a distance runner following a strict vegan diet, contributing to reduced oxygen-carrying capacity?

Accepted Answer

Iron

Answer

Iron deficiency is common in vegan endurance athletes because non-heme iron from plant sources has lower bioavailability than heme iron from animal products.

Question 4

What is the estimated energy cost of synthesizing approximately 1 pound of new muscle tissue?

Accepted Answer

~2,500 kcal

Answer

Building approximately 1 lb of skeletal muscle requires roughly 2,500 kcal above maintenance due to the metabolic cost of protein synthesis and supporting tissues.

Question 5

Which statement about caffeine's ergogenic mechanism is MOST accurate per current sports nutrition evidence?

Accepted Answer

It blocks adenosine receptors, reducing perceived exertion

Answer

Caffeine's primary ergogenic effect is antagonism of adenosine receptors in the central nervous system, which reduces perceived effort and fatigue.
