Question 1

An aerobics client reports muscle cramps during class. Which electrolyte imbalance is most commonly associated with exercise-induced muscle cramps?

Accepted Answer

All of the above can contribute

Answer

Exercise-induced muscle cramps can result from deficiencies in sodium, potassium, calcium, or magnesium — often a combination during heavy sweating.

Question 2

What is the recommended daily protein intake range for an individual regularly participating in aerobic exercise, per pound of body weight?

Accepted Answer

0.5–0.8 g/lb

Answer

Regularly active aerobic exercisers generally need 0.5–0.8 g of protein per pound of body weight (1.1–1.7 g/kg) to support repair and recovery.

Question 3

A client asks about sports drinks during a 45-minute moderate-intensity aerobics class. What is the best advice?

Accepted Answer

Water is sufficient for sessions under 60 minutes

Answer

For exercise lasting under 60 minutes at moderate intensity, water is adequate; sports drinks add unnecessary calories without significant benefit.

Question 4

Which vitamin is synthesized by the body through sun exposure and is important for calcium absorption and bone health in aerobics clients?

Accepted Answer

Vitamin D

Answer

Vitamin D is synthesized in the skin via UV exposure and is essential for calcium absorption, bone density, and muscle function.

Question 5

A client who is vegetarian and takes aerobics classes three times per week asks how to meet their iron needs. What is the best dietary advice?

Accepted Answer

Consume non-heme iron foods with vitamin C to enhance absorption

Answer

Non-heme iron from plant sources is less bioavailable, but consuming it alongside vitamin C significantly enhances its absorption.
