10%
 
15%
 
20%

Nutrients and Intakes

 
 
 
(4)Fish oil is a good source of __________.

Physiological Aspects of Nutrition

 
 
 
(5)Which muscle fiber distribution would be the most beneficial to a marathon runner?
 
 
A high density of Type I fibers
 
A high density of Type IIa fibers
 
A high density of Type IIx fibers
 
An equal distribution of all fibers
 
 
 
 

Physiological Aspects of Nutrition

 
 
 
(6)During high-intensity work fueled by anaerobic glycolysis, performance declines due to which of the following reasons?
 
 
Skeletal muscle can store only limited amounts of glycogen
 
Hydrogen ions are released, increasing muscle acidity
 
The rapid breakdown of glycogen promotes hypoglycemia
 
The rapid creation of glucose from glycogen promotes hyperglycemia
 
 
 
 

Physiological Aspects of Nutrition

 
 
 
(7)What percentage of heme iron consumed can be absorbed?
 
 
5%
 
20%
 
40%
 
45%
 
 
 
 

Physiological Aspects of Nutrition

 
 
 
(8)One way to decrease the risk of exercise-related gastrointestinal (GI) problems is to:
 
 
Avoid dairy products prior to exercise
 
Consume high-fructose beverages one hour prior to exercise to enhance blood glucose levels
 
Consume high fiber foods one hour pre-exercise to slow carbohydrate absorption and maximize blood glucose prior to exercise
 
Avoid consuming fluids both prior to and during exercise to prevent cramps
 
 
 
 

Macronutrients

 
 
 
(9)Research over the last 30 years has shown which nutrient to be most essential for athletic performance?
 
 
Protein
 
Fat
 
Carbohydrate
 
Vitamins
 
 
 
 

Macronutrients

 
 
 
(10)Which of the following is a disadvantage of the classical carbohydrate loading method?
 
 
The athlete may become hyperglycemic prior to competition
 
The athlete may consume less carbohydrate than needed during the depletion phase
 
The athlete may become moody and lethargic during the low-carbohydrate intake period
 
The method has failed to provide tangible results during a full marathon
 
 
 
 

Macronutrients

 
 
 
(11)All of the following affect fat utilization during exercise except:
 
 
Level of aerobic fitness
 
Level of body fatness
 
Duration of exercise
 
Carbohydrate intake during exercise
 
 
 
 

Macronutrients

10%
 
30%
 
50%
 
85%

(13)If an athlete is on an energy-restricted diet, adequate calcium intake can in part be ensured by consumption of which of the following food products?
 
 
Avocados
 
Chicken
 
Green leafy vegetables
 
Olive oil
 
 
 
 

Micronutrients and Supplementation

Athletes who perform heavy weight training
 
Athletes who train and compete in hot environments
 
Athletes returning after a long layoff
 
 
 
 

Micronutrients and Supplementation

 
 
 
(15)The mechanisms of action for caffeine include all of the following except:
 
 
Increased signaling from the brain to motor neurons
 
Increased excitability of muscle fibers.
 
Increased release and sensitivity to calcium in the myofibril.
 
Increased use of carbohydrates.
 
 
 
 

Micronutrients and Supplementation

 
 
 
(16)What is the function of creatine in muscle?
 
 
It functions as a structural component of myofilaments
 
It functions to release calcium in the sarcoplasmic reticulum
 
It functions as an immediate energy source
 
It functions to mobilize lipids for energy production
