Cardiorespiratory Fitness Training Flashcards

A client doing steady-state cardio can talk, but full sentences are starting to get harder. Which marker has the client most likely reached?

Answer: First ventilatory threshold (VT1)

At VT1, breathing rises enough that continuous talking becomes harder but is still possible.

In NASM's cardiorespiratory training stages, what is required before a client moves into Stage 3 (Zone 3) intervals?

Answer: Assessing the client's VT2 or high-end intensity tolerance

Stage 3 works above VT2, so the trainer must know where VT2 is and confirm the client can tolerate near-maximal work.

Elevated oxygen use after a hard interval session ends is called what?

Answer: Excess post-exercise oxygen consumption (EPOC)

EPOC is the extra oxygen used during recovery to restore homeostasis.

Current U.S. Physical Activity Guidelines recommend how much moderate-intensity aerobic activity per week for adults?

Answer: At least 150 minutes

Adults should get 150 minutes of moderate or 75 minutes of vigorous activity per week, or an equivalent mix.

In NASM's FITTE-VP framework, what does the 'E' stand for?

Answer: Enjoyment

NASM adds enjoyment to the FITT principle because a client who enjoys the program is more likely to stick with it.

Which structure acts as the heart's natural pacemaker?

Answer: Sinoatrial (SA) node

The SA node in the right atrium starts each electrical impulse and sets the heart rate.

A client with lower crossed syndrome wants cardio. Which equipment needs the most form monitoring because it keeps the hips flexed?

Answer: Stationary bike and stair stepper

Long periods of hip flexion can make short hip flexors and anterior pelvic tilt worse in lower crossed syndrome.
