NETA Cardiovascular Training 3

Question 1

What is the primary fuel source during low-intensity, long-duration aerobic exercise?

Accepted Answer

Fat (triglycerides)

Answer

During low-intensity, long-duration exercise, the oxidative system primarily relies on fat (triglycerides) as the main fuel source, sparing glycogen for higher-intensity efforts.

Question 2

Which cardiovascular exercise modality is generally considered the lowest impact on the joints?

Accepted Answer

Swimming or water aerobics

Answer

Swimming and water aerobics are the lowest impact on joints because water buoyancy reduces gravitational stress on the musculoskeletal system significantly.

Question 3

Cardiac output is defined as:

Accepted Answer

Heart rate multiplied by stroke volume

Answer

Cardiac output equals heart rate multiplied by stroke volume, representing the total volume of blood the heart pumps per minute.

Question 4

Heart rate drift during prolonged steady-state exercise is primarily caused by:

Accepted Answer

Dehydration reducing plasma volume and cardiovascular drift

Answer

Cardiovascular drift occurs during prolonged exercise as dehydration reduces plasma volume, causing heart rate to rise in order to maintain adequate cardiac output.

Question 5

The specificity principle states that:

Accepted Answer

Physiological adaptations are specific to the type, speed, and pattern of training performed

Answer

The specificity principle states that the body's physiological adaptations are specific to the type, speed, and pattern of training performed, meaning training must match the goal.
