Substitution
None of these is correct.
Which of the following is true of amino acids?
Essential amino acids are produced by the body.
Conditionally essential amino acids become essential under unusual circumstances.
Nonessential amino acids are not needed to make proteins, and thus serve little purpose in the body.
There are 11 essential amino acids.

Which of the following is not a function of proteins in the body?
They help maintain the body’s fluid balance.
They are a major source of energy during exercise.
They make up the majority of many body tissues.
They play a role in immune functioning.
They help control the acidity of body fluids.
Which of the following is true if an athlete is in a state of positive nitrogen balance?
Their protein consumption is greater than their protein breakdown in the body.
Their protein consumption is less than their protein excretion.
Their protein consumption equals their protein excretion.
It indicates that lean body tissue is being broken down by the body.
None of these is correct.
Jill is a 115-pound marathoner who is training hard for her next race. She is concerned about her protein intake and has come to you for help. Which of the following would be a prudent recommendation regarding protein intake?
Jill should consume approximately 35–40% of her total daily calories from proteins.
Jill doesn’t really need to concern herself with protein intake because she is an endurance athlete.
Jill should buy a good protein supplement and supplement her diet three times per day.
Jill should try to consume at least 62 grams of protein per day.
All of these are correct.

Which of the following is true of high-quality proteins?
They are also complete proteins.
They are derived primarily from animal sources.
They contain extra amino acids that can be used for making other amino acids.
They are more easily digested by the body compared to lower-quality proteins.
All of these are correct.
Which of the following best describes “complementing proteins”?
Proteins that provide a full complement of nonessential amino acids.
Proteins that cannot be made by the body and thus must be consumed in the diet.
Protein sources that when mixed together supply all of the essential amino acids.
Proteins that come only from plant sources.
All of these are correct.
Which athletes should be most concerned about “complementing proteins”?
Athletes who do not eat red meat but do eat fish and chicken
Athletes who consume no red meat but do eat eggs and consume dairy products
Athletes who eat red meat at every meal

Oligopeptides
Dipeptides
Tripeptides
Polypeptides
Monopeptides
Which of the following is not true regarding protein intake after exercise?
The consumption of essential amino acids after exercise has been shown to increase protein synthesis.
Ingestion of amino acids should begin as soon as possible after exercise.
Food sources that cause hyperaminoacidemia soon after exercise are recommended.
Combining carbohydrates and proteins immediately after exercise appears to be a prudent nutritional practice.
Hydrolyzed proteins are the best type of protein to ingest after exercise.
Protein supplementation may be necessary in athletes having trouble meeting their protein needs through the whole foods in their diet.
True
False
Research indicates that ingesting proteins prior to training can decrease muscle catabolism and increase muscle synthesis.
True
False
Athletes should experiment ahead of time with pregame meals, particularly those with a higher protein content, to minimize the risk of abdominal discomfort during actual games.
True
False
Hydrolyzed proteins are digested and absorbed more slowly than whole food sources of protein and should be avoided by athletes.
True
False
Dipeptides are proteins composed of 3 to 10 amino acids.
True
False
Vegetarian athletes have slightly higher protein needs compared to nonvegetarian athletes, due to the intake of incomplete protein food sources.
True
False
Athletes should strive to maintain adequate intake of carbohydrates because carbohydrate availability spares proteins.
True
False
Athletes desiring to either gain or lose weight should increase protein intake to the higher end of the recommended range.
True
False
The excessive consumption of protein offers athletes more benefits than risks with regard to health and sport performance.
True
False
