Question 1

Which energy availability threshold is associated with impaired physiological function in female athletes according to the RED-S model?

Accepted Answer

<30 kcal/kg FFM/day

Answer

Energy availability below 30 kcal/kg FFM/day is the established threshold associated with hormonal disruption and health consequences in female athletes.

Question 2

An athlete's body weight has plateaued despite maintaining a 400 kcal/day deficit for 8 weeks. The MOST likely physiological explanation is:

Accepted Answer

Adaptive thermogenesis has reduced total energy expenditure

Answer

Adaptive thermogenesis causes the body to downregulate NEAT, RMR, and TEF in response to sustained caloric restriction, slowing weight loss over time.

Question 3

Which biomarker is MOST sensitive for detecting early metabolic adaptation to low energy availability in athletes?

Accepted Answer

Triiodothyronine (T3)

Answer

T3 is highly sensitive to energy availability and decreases rapidly with caloric restriction, making it a useful early marker of metabolic adaptation.

Question 4

A 65 kg female soccer player wants to lose 4 kg of fat in 8 weeks. Approximately what weekly caloric deficit is needed?

Accepted Answer

500 kcal/day

Answer

Losing 0.5 kg/week requires roughly a 500 kcal/day deficit (3,500 kcal ≈ 0.45 kg fat), totaling ~4 kg over 8 weeks.

Question 5

Compared to aerobic exercise, resistance training's contribution to acute caloric expenditure is generally:

Accepted Answer

Lower per session but produces greater excess post-exercise oxygen consumption (EPOC)

Answer

Resistance training burns fewer calories acutely per session than aerobic exercise but generates greater EPOC, elevating metabolism for hours post-workout.
