Straighterline Nutrition FINAL
physical fitness - correct answer the ability to perform moderate to vigorous
activity without undue fatigue
ATP (adenosine triphosphate) - correct answer the main energy currency for
cells. Used to promote ion pumping, enzyme activity, and muscular contraction.
The immediate source of energy for body functions.
ADP (adenosine diphosphate) - correct answer A breakdown product of ATP.
Synthesized into ATP using energy from foodstuffs and a phosphate group.
phosphocreatine (PCr) - correct answer A high-energy compound that can be
used to re-form ATP. It is used primarily during bursts of activity, such as lifting
and jumping.
creatine - correct answer An organic (i.e. carbon containing) molecule in muscle
cells that serves as a part of a high-energy compound (termed creatingphosphate
or phosphocreatine) cable of synthesizing ATP from ADP.
The primary goal in the use of any fuel (carb, fat, protein) - correct answer to
make ATP.
First line of defense for resupplying ATP in muscles - correct answer PCr
(phosphocreating)
The main advantage of phosphocreatine - correct answer It can be activated
instantly and can replenish ATP at rates fast enough to meet the energy demands
of the fastest and most powerful actions.
Disadvantage of phosphocreatine - correct answer Not much of it is made and
stored in the muscles
Ues of glucose to make ATP can be either __ or __ - correct answer anaerobic or
aerobic
Anaerobic glucose breakdown - correct answer yields energy fast. It provides
most of the energy needed for events that require a quick burst of energy
(sprints)
Disadvantage of the anaerobic breakdown of glucose - correct answer (1) cannot
be sustained for long periods of time and (2) the rapid accumulation of lactic acid
greatly increases the acidity of the muscle.
,Straighterline Nutrition FINAL
pyruvic acid - correct answer a three-carbon compound formed during glucose
metabolism, also called pyruvate
lactic acid - correct answer A three-carbon acid formed during anaerobic cell
metabolism; a partial breakdown product of glucose; also called lactate.
Aerobic glucose breakdown is a ___ energy source - correct answer sustained
aerobic breakdown of glucose yields approximately __ percent of the ATP made
from complete glucose metabolism - correct answer 95%.
Products of aerobic glucose breakdown - correct answer carbon dioxide and
water as opposed to the lactic acid of anaerobic glucose breakdown
bonking - correct answer diminished mental ability as the result of blood glucose
declining during exercise
Fall in blood glucose during exercise is related to the depletion of ____ glycogen -
correct answer liver (not muscle0
____ glycogen is used to maintain blood glucose - correct answer liver
what is the main fuel for prolonged low-intensity activity - correct answer fat
for lengthy activities at a moderate pace, fat supplies how much of the energy
required? - correct answer 70-90%
The only fast-paced anaerobic fuel we eat is - correct answer carbohydrate
Slow and steady aerobid activity uses___ in addition to ___ - correct answer
fat/carbohydrateq
amino acids derived from protein only supply about ___ of the body's general
energy needs. - correct answer 5%. 10-15% during endurance exercise.
the primary muscle fuels for weightlifting are - correct answer PCr and
carbohydrate for the brief bursts of energy, and fat during the resting states
Is it possible to increase muscle mass by eating protein? - correct answer No.
Physical strain/strength training is needed.
Estimated calories to sustain moderate activity - correct answer 5-8 kcal/minute
Recommended carbohydrate intake for athletes - correct answer 60% or more
,Straighterline Nutrition FINAL
Three major causes of fatigue in athletes - correct answer depletion of fluid;
depletion of electrolytes, and depletion of carbohydrates
carbohydrate loading - correct answer high carbohydrate intake is consumed for
6 days before an athletic event while tapering exercise duration in an attempt to
increase muscle glycogen stores.
The amount of activity would be for events lasting more than 60-90 minutes so it
applies to relatively few athletes.
Purpose of carbohydrate loading - correct answer to increase muscle glycogen
stores by 50-85% over typical conditions.
disadvantage of carbohydrate loading - correct answer additional water (about 3
grams) is incorporated into the muscles along with each gram of glycogen.
Additional water weight and muscle stiffness can detract from sports
performance.
consuming carbs ___ a competition provides about the same advantage as carb
loading - correct answer during
fat needs for athletes - correct answer up to 35% of calories from fat
protein needs for athletes - correct answer 1.0 - 1.6 grams of protein per kg of
body weight.
protein needs for non athletes - correct answer .8 grams per kg of body weight
heat exhaustion - correct answer The first stage of heat-related illness that
occurs because of depletion of blood volume from fuluid loss by the body. This
increases body temperature and can lead to headache, dizziness, muscle
weakness, and visual disturbances etc.
heat crams - correct answer A frequent complication of heat exhaustion. They
usually occur in people who have experienced large sweat losses from exercising
for several hours in a hot climate and have consumed a large volume of water.
The cramps occur in skeletal muscles and consist of contractions for 1 to 3
minutes at a time.
, Straighterline Nutrition FINAL
heat stroke - correct answer Heatstroke can occur when internal body
temperature reaches 104 degrees F. Seating generally ceases if left untreated,
and blood circulation is greatly reduced. Nervous system damage may ensue, and
death is likely. Often the skin of individuals who suffer heatstroke is hot and dry.
Water vs sports drinks - correct answer less than 60 minutes or less than 5-6
pounds lost...water. Otherwise sports drinks for the electrolytes and carbohydrate
replacement.
hyponatremia - correct answer water intoxication
ergogenic - correct answer work-producing. An ergogenic aid is a mechanical,
nutritional, psychological, pharmacological, or physiological substance or
treatment intended to directly improve exercise performance.
What is the most potential single indicator of infant's future health - correct
answer Birth weight
Know if overweight pregnant women should lose weight during pregnancy -
correct answer Health care providers advise against losing weight and advocate
following a well-balanced, calorie restricted diet, and regular exercise program in
order to gain little to no weight

trimester

What is the weight gain range for normal weight women - correct answer 25-35
pounds
What is the recommended weight gain range for overweight pregnant women -
correct answer 15-25 pounds
Which nutrient is associated with developing neural tube defects? - correct
answer Folic acid
