Choose the correct answer for each question. Only one answer is correct.
The primary energy system fueling the muscle of a runner during a marathon is:
anaerobic production of ATP from creatine phosphate and ADP
anaerobic production of ATP from free fatty acids
aerobic production of ATP from protein
aerobic production of ATP from free fatty acids
anaerobic production of ATP from glucose
During physical activity, water loss increases significantly via:
sweat
urine
respiration
two of the above
all of the above
Replenishing energy during activity:
is important for activities lasting 30 minutes or less
is beneficial for assisting in weight loss
helps maintain blood glucose for activities lasting longer than one hour
all of the above
none of the above
Benefits of physical fitness include:
improved sleep
health body composition
reduced stress and anxiety
improved cognitive functioning, alertness, and memory
all of the above
What is the primary fuel for activities of extremely high intensity lasting only 8 - 10 seconds?
ATP-CP
anaerobic glycolysis
aerobic glycolysis
fatty acid oxidation
protein
What is the primary fuel for activities of very high intensity lasting 20 seconds to 3 minutes?
ATP-CP
anaerobic glycolysis
aerobic glycolysis
fatty acid oxidation
protein
What is the primary fuel for activities of high intensity lasting 3 - 20 minutes?
ATP-CP
anaerobic glycolysis
aerobic glycolysis
fatty acid oxidation
protein
What is the primary fuel for activities of moderate intensity lasting longer than 60 minutes?
ATP-CP
anaerobic glycolysis
aerobic glycolysis
fatty acid oxidation
protein
Which of the following is NOT one of the primary fuels used to support physical activity?
ATP-CP
glucose
protein
fatty acids
none; all of the above provide a significant contribution to fuel use during activity
Maximal endurance time is greatest for a diet composed of:
high fat
high protein
high carbohydrates
mixed
maximal endurance time is not affected by meal composition
As the duration of an activity increases:
there is an increase in fat metabolism
there is a increase in carbohydrate metabolism
there is an increase in both carbohydrate and fat metabolism
there is a decrease in both carbohydrate anf fat metabolism
there is a decrease in fat metabolism
As the intensity of an activity increases:
there is an increase in fat metabolism
there is a increase in carbohydrate metabolism
there is an increase in both carbohydrate and fat metabolism
there is a decrease in both carbohydrate anf fat metabolism
there is a decrease in carbohydrate metabolism
Protein use as fuel during activity increases with:
high dietary protein intake
increased duration of activity
increased intensity of activity
a and b
b and c
The optimal diet to support physical activity should include:
protein supplements
plenty of water and other fluids
extra vitamins and minerals to enhance performance
all of the above
none of the above
According to Canada's Guide to Healthy Active Living, we should:
reduce sitting for long periods of time
increase endurance activities to 2 - 4 times per week
increase flexibility activities to 4 - 7 times per week
two of the above
all of the above
Adaptations to endurance training include:
an increase in the number of mitochondria within muscle cells
increased number of capillaries to supply oxygen and energy to working muscles
an enhance ability to use fat as energy
two of the above
all of the above
Althetes require supplements to meet protein needs because:
protein is a primary energy source to fuel athletic activity
protein needs cannot be met through a healthy balance diet
more protein is require to build and maintain muscles
all of the above
none of the above
Protein use as a fuel for physical activity:
decreases with an increased protein intake
decreases with increased strength training
decreases with increased duration of activity
increases with increased intensity of activity
all of the above
How does proportional utilization of carbohydrates and lipids change as the duration of an activity increases and the intensity of the activity decreases?
use of both fuels increases
use of carbohydrates increases, while use of lipids declines
use of carbohydrates decreases, while use of lipids increases
use of both fuels decreases as protein becomes the predominant fuel source
none of the above
How does proportional utilization of carbohydrates and lipids change as the duration of an activity decreases and the intensity of the activity increases?
