What condition results from excessive water intake without adequate sodium replacement during endurance events?
Answer: Hyponatremia
Hyponatremia occurs when blood sodium levels drop dangerously low, often from drinking too much plain water without replacing sodium lost in sweat.
Which body composition assessment method uses low-level X-ray beams to differentiate bone, fat, and lean tissue and is considered a gold standard?
Answer: Dual-energy X-ray absorptiometry (DEXA)
DEXA scanning uses dual-energy X-ray beams to precisely measure bone mineral density, fat mass, and lean tissue, making it a gold standard for body composition analysis.
What does 'relative energy deficiency in sport' (RED-S) describe?
Answer: A syndrome caused by insufficient caloric intake relative to energy expended in training
RED-S describes a syndrome where athletes consume too few calories relative to their training demands, impairing hormonal, bone, cardiovascular, and psychological health.
Which fat type, found in foods like salmon and walnuts, has anti-inflammatory properties beneficial for athletic recovery?
Answer: Omega-3 fatty acids
Omega-3 fatty acids, particularly EPA and DHA found in fatty fish, have well-documented anti-inflammatory effects that support muscle recovery and reduce exercise-induced inflammation.
What is the general hydration recommendation for athletes before exercise to ensure they begin training euhydrated?
Answer: Consume 17–20 oz of water 2–3 hours before exercise
The NATA and ACSM recommend consuming 17–20 ounces of water 2–3 hours before exercise to optimize hydration status before training begins.
Which mineral deficiency is most commonly associated with muscle cramps, poor bone density, and irregular heartbeat in athletes?
Answer: Magnesium
Magnesium deficiency is strongly linked to muscle cramps, reduced bone mineral density, and cardiac arrhythmias, making it an important mineral for athletic populations.
