NETA Cardiovascular Training 3

Question 1

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

Accepted Answer

Fat (triglycerides)

Answer

Muscle glycogen

Answer

Blood glucose only

Answer

Dietary protein

Question 2

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

Accepted Answer

Swimming or water aerobics

Answer

Running on a treadmill

Answer

Jumping rope

Answer

Step aerobics

Question 3

Cardiac output is defined as:

Accepted Answer

Heart rate multiplied by stroke volume

Answer

The force generated by each ventricular contraction

Answer

The volume of blood ejected per heartbeat only

Answer

The oxygen saturation percentage of arterial blood

Question 4

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

Accepted Answer

Dehydration reducing plasma volume and cardiovascular drift

Answer

Increased muscle glycogen stores mid-exercise

Answer

Decreased breathing rate over time

Answer

Reduced lactic acid production as exercise continues

Question 5

The specificity principle states that:

Accepted Answer

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

Answer

All forms of exercise provide equal fitness benefits regardless of type

Answer

Rest is more important than training volume for adaptation

Answer

Volume should always exceed intensity in program design

Question 6

Which of the following best defines interval training?

Accepted Answer

Alternating between periods of higher-intensity effort and lower-intensity recovery

Answer

Exercising at the exact same pace for an entire session

Answer

Performing only flexibility and stretching exercises in sequence

Answer

Completing resistance exercises in a continuous circuit without rest

Question 7

For a previously sedentary, deconditioned client beginning cardiovascular training, which approach is most appropriate?

Accepted Answer

Start with 10–20 minutes of low-to-moderate intensity exercise 2–3 days per week

Answer

Begin with HIIT sessions 5 days per week immediately

Answer

Start with 45-minute continuous moderate-intensity runs

Answer

Perform near-maximal effort training to accelerate adaptation
