All of the following are benefits of aerobic training except
The body makes more red blood cells to transport more oxygen to the muscles
Arteries get stiff and rigid allowing for decreased blood flow
More capillaries form in the muscle to more efficiently exchange O2 and CO2
Muscles, including the heart, "hypertrophy" (get thicker) for more forceful contractions
It takes longer for your heart rate to return to normal after exercise as aerobic fitness improves.
True
False
The respiratory system includes the
heart, arteries, veins and capillaries
nose, mouth, lungs, diaphram
heart, muscles, bones
heart, lungs, blood vessels
In the lungs, oxygen (O2) and carbon dioxide (CO2) are exchanged through the process of diffusion in the small air sacs known as the
bronchial's
diaphragm
capillaries
alveoli
The process of breathing is known as
inspiration
exhalation
respiration
inhalation
The type of muscle that contracts and relaxes without any conscious thought is
a voluntary muscle
an involuntary muscle
Which of the following are controlled by involuntary muscles? (Pick all that apply)
The lungs
The skeletal muscles (like the biceps)
The heart
Glucose/Glycogen (the stored form of glucose) supplies continuous energy for aerobic activity for up to
30 seconds
2 minutes
60 minutes
2 hours
The energy compound that allows muscles to work is known as
Actin
ADP
ATP
Myosin
The first energy system used in high-intensity activities is the
ATP-PC energy system
Anaerobic lactic acid energy system
Aerobic energy system
There are _______ anaerobic energy systems.
1
2
3
The reaction of the breakdown of glycogen in the anaerobic energy system is known as
anaerobic glycolosis
anaerobic synthesis
lactic acid
The waste product produced by the aerobic energy system is: (Select all that apply)
Creatine Phosphate
Carbon Dioxide
Lactic Acid
Water
Which energy system requires oxygen?
Anaerobic energy system
Aerobic energy system
ATP stands for what?
Aerobic Tri-potassium
Anaerobic Triple Phosphate
Adrenaline Twitch Protein
Adenosine Tri-phosphate
Energy (ATP) production occurs in the myofibrils (which are single muscle fibers within the muscle).
True
False
The ATP - PC System usually lasts for how long?
0-10 seconds
10 seconds - 2 minutes
2 + minutes
1 hour +
Which of the following is true about the aerobic energy system? (Pick all that apply)
After 30 seconds of intense physical activity, large amounts of oxygen become available to the muscles
Requires the heart, lungs and circulatory system to provide oxygen to the muscles
Relies of oxygen for energy production
Causes lactic acid to buildup in muscles making them hurt and stiff, which requires rest
Energy systems work in which of the following ways?
Independently (one at a time)
Together (all working to varying degrees)
Evenly (all working to the same degree)
Sequentially (first, then second, then third)
