Question 1

What is the primary energy system used during steady-state aerobic exercise lasting more than 3 minutes?

Accepted Answer

Oxidative system

Answer

The oxidative (aerobic) energy system is the primary source for sustained exercise lasting more than 3 minutes, using oxygen to produce ATP.

Question 2

According to ACSM guidelines, how many minutes of moderate-intensity cardiorespiratory exercise per week is recommended for healthy adults?

Accepted Answer

150 minutes

Answer

ACSM recommends at least 150 minutes of moderate-intensity cardiorespiratory exercise per week for healthy adults to achieve health benefits.

Question 3

Which formula is most commonly used to estimate maximum heart rate in apparently healthy adults?

Accepted Answer

220 - age

Answer

The most commonly used formula to estimate maximum heart rate is 220 minus the individual's age, though it carries a standard deviation of about ±10–12 bpm.

Question 4

What does the Karvonen formula calculate in cardiovascular exercise programming?

Accepted Answer

Target heart rate training zones

Answer

The Karvonen formula calculates target heart rate training zones using heart rate reserve (HRmax minus HRrest), providing a more individualized prescription than percentage of HRmax alone.

Question 5

During a HIIT session using a 1:2 work-to-rest ratio, if the work interval is 30 seconds, how long is the rest period?

Accepted Answer

60 seconds

Answer

A 1:2 work-to-rest ratio means the rest period is twice the length of the work interval, so 30 seconds of work is followed by 60 seconds of rest.
