Total questions: 26
Worksheet time: 13mins
Which of these is a immediate effect of physical exercise?
Increased Breathing Rate
Lower resting Heart Rate
Lower Breathing Rate
Bigger and stronger Muscles
Muscular fatigue is caused by a build up of?
Energy
Glucose
Lactic acid
Oxygen
During exercise, your breathing rate increased in order to accommodate:
Increased carbon dioxide needs of your muscles
Increased oxygen needs of your stomach
Increased oxygen needs of your muscles
Increased carbon dioxide needs of your stomach
Which process helps remove excess heat from your body?
Shivering
Sweating
Increased energy use
Producing lactic acid
Our breathing rate increases and you start to breathe heavily, this happens because
More blood gets circulated around the body
We have started to perform a physical activity
To break down Lactic Acid and replenish energy supplies.
Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
Selective Redistribution of Blood occurs when:
To prevent the overheating of muscle tissue
Because of the increased need for oxygen and removal of Carbon Dioxide
Arteries dilate or constrict selectively to direct blood flow from non working muscles
Cardiac Output increases
The body's main source of energy
Protein
Vitamins
minerals
Carbohydrates
Anaerobic exercises require ______ whereas aerobic exercises require ______.
No energy, energy
Energy, no energy
Oxygen, no oxygen
No oxygen, oxygen
ATP stands for what?
Aerobic Tri-potassium
Adenosine Tri-phosphate
Adrenaline Twitch Protein
Anaerobic Triple Phosphate
Why does the body require the three different energy systems?
It doesn't require three different systems
Different sports have different demands
Intensity and duration of different activities and the availability of oxygen
Physical exercise usually takes longer than a few minutes
The ATP - PC System usually lasts for how long?
0-10 seconds
10 seconds - 2 minutes
2 + minutes
1 hour +
The Lactic Acid System usually lasts for how long?
0-10 seconds
10 seconds - 2 minutes
2 + minutes
1 hour +
The ATP - PC System usually takes how long to replenish?
10-14 seconds
1-2 minutes
30+ minutes
12+ hours

Which of the following is an immediate response to exercise?
Increased heart rate
Increased body temperature
Increased blood flow
All of the above
What is stroke volume
How many times the heart beats per minute
How much blood can be pumped per beat of the heart
How much oxygen our blood can carry
How many times we breathe in a minute
why does blood flow change during exercise (pick 2)
increase delivery of O2 to working muscles
decrease stroke volume
removal of CO2/waste from the muscles
decrease breathing rate
what will happen to blood pressure during isometric contraction
increases
decreases
no change
What is Arteriovenous oxygen difference (a-VO2 diff)
difference of blood flow in the muscle
difference of blood O2 in the arterial blood compared to the venous blood
difference of CO2 entering and leaving the lungs
difference of lactic acid in the muscle before and after
What is continuous training?
Performing a set of exercises in a circuit
Running at a steady pace for a set period of time
Running for a period of time, then resting, then running again
Lifting weights
What is progressive overload?
Lifting the same weight.
Gradually increasing the load of training
Changing the types of exercise you are doing
How many times a week you train
Which of the following is a long term response to exercise
Decreased resting heart rate
Increased muscular strength
Increased muscular endurance
All of the above
What would be the dominant Energy System used in a game of Basketball?
ATP-PC
Lactic Acid
Aerobic
