1. What is Oxygen Debt?
2. What does EPOC stand for?
3. Explain the connection between these two terms
1. A temporary shortage of the body tissues arising from exercise/the amount of oxygen needed to bring the body back to normal
2. Excess Post-Exercise Oxygen Consumption
3. Oxygen Debt is paid back through the process of EPOC
Why might feelings of nausea occur during exercise?
Blood flow is directed away from the digestive system to the working muscles.
1. Define Stroke Volume
2. Describe the difference in stroke volume for an elite athlete and an average person
1. The volume of blood pumped out of the heart in one beat (measured in ml)
2. An elite athlete will have a higher stroke volume (around 90ml) that an average person (around 70 ml)

State and Explain 5 Factors that influence how quickly someone can recover after exercise.
Strength & Fitness

Sleep
Why does the skin become red during exercise?
Warm blood rushed to the surface to be cooled down.
Blood vessels close to the skin become enlarged, increasing blood flow and therefore heat loss through radiation.
Why do elite athletes have lower heart rate?
Their heart can contract more forcefully (Stronger)
Their heart can hold more blood (Larger)
Their stroke volume is higher than an average person so their heart does not need to beat as many times to deliver oxygenated blood.

心肌變厚,也稱為肥厚; 增厚的心肌會增加心臟泵血的難度
Cardiac Hypertrophy
Write the equations for both Aerobic and Anaerobic Respiration.
Aerobic Respiration:
Glucose + Oxygen --> Water + Carbon Dioxide (+Energy)
Anaerobic Respiration:
Glucose --> Lactic Acid (+Energy)
Write the Lactic Acid Equation.
Lactic Acid + Oxygen -->Water + Carbon Dioxide + Glucose
Blood pressure can drop after exercise due to enlarged blood vessels. This can affect oxygen delivery to the brain. This can cause?

1. Which type of training will produce lactic acid?
2. True or False - Over time, Lactic Acid tolerance can be improved through interval training.
1. Interval Training (intensity activity w/ short rest period)
2. TRUE
