DHN 101 Final Exam Questions With Correct
Answers
There are three primary energy systems utilized by exercising muscles. Match
| | | | | | | | | | |
each system with the duration of exercise the system supports: - ANSWER✔✔✔-
| | | | | | | | | | |
PCr-ATP Energy System: Exercise lasting a few seconds correct
| | | | | | | |
Lactic Acid Energy System: Exercise lasting 30-40 seconds correct
| | | | | | | |
Oxygen Energy System: Endurance exercise activities correct
| | | | | |
Anthony is training for a half-marathon. On long-run days, which of the following
| | | | | | | | | | | | |
snacks would be the most appropriate to consume after one hour of running and
| | | | | | | | | | | | | |
why? - ANSWER✔✔✔-A banana and pretzels because they provide carbohydrate,
| | | | | | | | |
which helps prevent fatigue.
| | | |
Anthony is training for a half-marathon. He trains for more than 90 minutes most
| | | | | | | | | | | | | |
days of the week. Calculate the minimum number of kilocalories Anthony should
| | | | | | | | | | | |
consume daily to maintain his weight while training (165 pounds). -
| | | | | | | | | | |
ANSWER✔✔✔-3,750
Carbohydrates are an important macronutrient for fueling muscles. During
| | | | | | | | |
exercise, where can the body obtain carbohydrate? Check all that apply: -
| | | | | | | | | | | |
ANSWER✔✔✔-Glycogen stored in muscles | | |
Glycogen stored in the liver cells
| | | | |
Glucose that is available in the bloodstream
| | | | | |
|
, The immediate source of glucose for working muscles is glycogen that is stored in
| | | | | | | | | | | | | |
muscles. The liver also helps supply glucose for muscles by degrading glycogen
| | | | | | | | | | | |
and releasing glucose molecules into the bloodstream.
| | | | | |
Consider each statement about protein for athletes and determine whether it is
| | | | | | | | | | | |
true or false. - ANSWER✔✔✔-TRUE:
| | | |
-the amino acids from dietary protein included in a small meal or snack after
| | | | | | | | | | | | | |
strenuous exercise can help muscle cells repair damaged muscle tissue by
| | | | | | | | | | |
synthesizing new proteins | |
-excess protein may be stored as fat
| | | | | |
-the National Academy of Sciences maintains that no additional dietary protein is
| | | | | | | | | | | |
suggested for healthy adults undertaking resistance or endurance exercise
| | | | | | | |
FALSE:
-protein is a major biological fuel used during activity
| | | | | | | |
-excess protein is stored in muscle tissue
| | | | | |
-according to the Academy of Nutrition and Dietetics, protein intake for athletes
| | | | | | | | | | | |
should be at least 4.0 g/kg/day
| | | | |
Anaerobic glucose breakdown - ANSWER✔✔✔--glucose degrades into pyruvate
| | | | | | | |
under these conditions
| |
-provides most of the energy needed fro events that require a quick burst of
| | | | | | | | | | | | | |
energy, ranging from about 30 seconds to 2 minutes
| | | | | | | |
-occurs when oxygen supply in the muscle is limited
| | | | | | | |
-produces relatively small amounts of ATP
| | | | |
