SPORTS NUTRITION EXAM
QUESTIONS AND ANSWERS
Aerobic system - answer-many steps involved, very slow but a lot of atp
What are the functions of carbohydrates ? - answer-energy source, metabolic primer
for fat metabolism, prevents protein catabolism in body
What are the recommendations for carbohydrate intake for athletes ? - answer-6-10
g/kg of body weight
What is the glycemic index? - answer-indicates how much a certain food raises
blood glucose levels when consumed in isolation
Phosphagen system - answer-provides atp fast but doesn't get as much
Anaerobic system - answer-slower, but more atp than phosphagen
Hitting the wall - answer-depleted muscle glycogen
Bonking - answer-depleted liver stores
Stale - answer-chronic fatigue that occurs when athletes consume inadequate
amounts to train hard daily
How long does it typically take to replenish glycogen stores? - answer-about 20 or
more hours
What is carbohydrate loading? - answer-muscle glycogen super saturation and has
been shown to increase levels above normal for longer sports
What is the crossover point? - answer-the point at which carbohydrates take over as
the primary energy source
High-quality protein - answer-complete protein
Low-quality protein - answer-incomplete protein
What are complementing proteins ? - answer-proteins sources that when mixed
together supply all of the essential amino acids
What is nitrogen balance? - answer-an indicator of nitrogen status and thus protein
intake
Equals:(nitrogen in)-(nitrogen out)
What are the best sources of leucine? - answer-beef, chicken, tuna, milk
