Year 12 PE SAC 3 Revision Acute Responses

What are the immediate short-term responses of the body to exercise referred to as?

• Chronic responses

• Acute responses

• Delayed responses

• Long-term responses

Which systems are examined in the chapter on acute physiological responses to exercise?

• Digestive and nervous systems

• Endocrine and lymphatic systems

• Cardiovascular, respiratory, and muscular systems

• Skeletal and integumentary systems

Which of the following is an acute physiological response to exercise in the cardiovascular system?

• Increased muscle temperature

• Increased blood flow

• Increased respiratory frequency

• Increased oxygen uptake

Which of the following is an acute physiological response to exercise in the respiratory system?

• Increased muscle enzyme activity

• Increased motor unit and fibre recruitment

• Increased ventilation

• Depleted muscle energy stores

What are acute responses of the cardiovascular system designed to facilitate?

• Increased amounts of oxygen to the working muscles

• Decreased heart rate

• Reduced blood pressure

• Decreased stroke volume

Which of the following is NOT an acute response of the cardiovascular system to exercise?

• Increased heart rate

• Increased stroke volume

• Decreased cardiac output

• Redistribution of blood flow to working muscles

What does the term "heart rate" (HR) refer to?

• The number of times the heart contracts or beats per minute

• The amount of blood pumped by the heart per beat

• The pressure of blood in the arteries

• The volume of blood in the heart

What is the average resting heart rate (RHR) for an adult?

• 60-80 beats per minute

• 40-60 beats per minute

• 80-100 beats per minute

• 100-120 beats per minute

How can the maximum heart rate (MHR) be estimated?

• By subtracting the age of the individual from 220

• By adding the age of the individual to 220

• By multiplying the age of the individual by 2

• By dividing the age of the individual by 2

What happens to heart rate as exercise intensity increases?

• It increases linearly until near-maximal intensity is reached

• It decreases linearly until near-maximal intensity is reached

• It remains constant regardless of exercise intensity

• It decreases exponentially
