Exercise Physiology - Senior PE

During a competitive 100-meter dash, which energy system is primarily responsible for providing the burst of energy athletes need?

• Aerobic Glycolysis System

• ATP-PC System

• Anaerobic Glycolysis System

• Lactic Anaerobic System

During a marathon, which energy system does a runner primarily rely on for sustained energy production?

• Alactic Anaerobic System

• Glycolytic System

• Aerobic Glycolysis System

• Anaerobic Glycolysis System

What is the primary purpose of chronic training adaptations?

• Increase short-term energy production

• Enhance acute response to exercise

• Improve long-term performance and fitness

• Minimize fatigue during exercise

Which fitness component is most associated with the ability of muscles to exert force repeatedly over an extended period?

• Muscular strength

• Flexibility

• Muscular endurance

• Power

In the context of fitness, what does VO2 max measure?

• Anaerobic power

• Maximum heart rate

• Aerobic capacity

• Lactic acid threshold

During a sprint, how does an athlete's body acutely respond in terms of heart rate and breathing rate?

• Decreased heart rate, increased breathing rate

• Increased heart rate, decreased breathing rate

• Increased heart rate, increased breathing rate

• Decreased heart rate, decreased breathing rate

Which scenario represents an example of aerobic exercise?

• Weightlifting for 1 rep max

• Sprinting for 30 seconds

• Jogging in the park for 30 minutes

• High-intensity interval training (HIIT) at the gym

Imagine you're in a basketball game and you need to make a quick jump to score a basket. What is the main source of energy your body uses in those initial seconds of high-intensity effort?

• Oxygen

• Glucose

• Fatty acids

• ATP-PC System

What is lactate threshold, and how does it relate to exercise performance?

• The point at which muscles become fatigued

• The point at which blood lactate begins to accumulate

• The maximum heart rate during exercise

• The point when ATP-PC system is activated

How does regular aerobic exercise contribute to cardiovascular health?

• Decreases resting heart rate

• Increases blood pressure

• Enhances oxygen delivery to tissues

• Reduces lung capacity
