Question 1

What physiological adaptation increases stroke volume at rest following regular aerobic training?

Accepted Answer

Cardiac hypertrophy and increased end-diastolic volume

Answer

Regular aerobic training causes the left ventricle to hypertrophy and fill with more blood during diastole, increasing stroke volume at rest and during exercise.

Question 2

Which zone training intensity is associated with the lactate threshold?

Accepted Answer

60–70% VO2 max

Answer

The lactate threshold typically occurs at approximately 60–70% of VO2 max in untrained individuals and represents the point where lactate begins to accumulate in the blood.

Question 3

What is the primary purpose of a talk test during cardiorespiratory exercise?

Accepted Answer

To estimate exercise intensity based on conversational ability

Answer

The talk test is a simple method to gauge exercise intensity: if a client can comfortably hold a conversation, they are at moderate intensity.

Question 4

Interval training alternates periods of high intensity with periods of what?

Accepted Answer

Active recovery or rest

Answer

Interval training involves alternating bouts of high-intensity exercise with lower-intensity recovery periods to allow partial recovery before the next work interval.

Question 5

Which acute cardiovascular response occurs during aerobic exercise?

Accepted Answer

Increased systolic blood pressure

Answer

Systolic blood pressure rises during aerobic exercise due to increased cardiac output, while diastolic blood pressure remains relatively stable or decreases slightly.
