Which WADA-banned substance class includes peptide hormones such as erythropoietin (EPO)?
Answer: S2 Peptide hormones, growth factors, related substances
EPO falls under WADA Section S2 (Peptide hormones, growth factors, related substances and mimetics), which is prohibited at all times.
The 'female athlete triad' consists of energy deficiency, menstrual dysfunction, and:
Answer: Low bone mineral density
The classic female athlete triad consists of low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density.
Which amino acid is the primary precursor for nitric oxide synthesis and may improve exercise performance via vasodilation?
Answer: L-arginine
L-arginine is the primary substrate for nitric oxide synthase, and its supplementation may enhance blood flow and oxygen delivery to muscles.
A marathon runner complains of fatigue and poor performance. Serum ferritin is 8 ng/mL. The MOST likely diagnosis affecting performance is:
Answer: Iron depletion without anemia (stage 2)
Ferritin of 8 ng/mL indicates stage 2 iron depletion (iron-deficient erythropoiesis) without frank anemia, which still impairs endurance performance.
Which dietary fat is most associated with reducing cardiovascular disease risk and has documented anti-inflammatory properties relevant to athletic recovery?
Answer: Omega-3 fatty acids (EPA/DHA)
Omega-3 fatty acids (EPA and DHA), found in fatty fish and fish oil, reduce pro-inflammatory eicosanoids and are associated with cardiovascular and recovery benefits.
Caffeine is believed to enhance endurance performance primarily through which mechanism?
Answer: Adenosine receptor antagonism reducing perceived effort
Caffeine blocks adenosine receptors in the brain, reducing perceived exertion and pain, which allows athletes to maintain higher intensities longer.
Which ergogenic aid is classified as a 'conditionally essential' amino acid that supports immune function and gut integrity in overtrained athletes?
Answer: Glutamine
Glutamine becomes conditionally essential during high training loads; it fuels enterocytes and immune cells (lymphocytes, macrophages), helping maintain gut integrity and immunity.
