Cardiorespiratory Training Flashcards

Ventilatory threshold 1 (VT1) is most accurately described as the point at which:

Answer: Breathing begins to increase disproportionately to oxygen demand

VT1 represents the exercise intensity where ventilation begins to increase non-linearly relative to oxygen consumption, signaling a shift toward greater anaerobic contribution.

For most healthy adults, maximum heart rate is estimated using the formula:

Answer: 220 − age

The widely used estimate for maximum heart rate is 220 minus the client's age in years, though more precise formulas exist.

Which training principle states that the body adapts to the specific demands placed upon it?

Answer: SAID principle (Specific Adaptation to Imposed Demands)

The SAID principle holds that the body makes specific physiological adaptations in direct response to the type and intensity of training stress applied.

Which of the following is the MOST common method NASM uses to prescribe cardiorespiratory intensity?

Answer: Heart rate zones based on HRmax or HRR

NASM recommends prescribing cardiorespiratory intensity using heart rate zones derived from maximum heart rate or heart rate reserve, as these are practical and measurable.

Interval training differs from steady-state training in that it:

Answer: Alternates periods of higher-intensity effort with recovery periods

Interval training alternates bouts of elevated intensity with recovery periods, producing greater improvements in VO2 max and caloric expenditure per session than steady-state work.

The primary long-term adaptation to consistent aerobic training on cardiac output is:

Answer: Increased stroke volume and decreased resting heart rate

Chronic aerobic training causes cardiac hypertrophy and increased blood volume, resulting in greater stroke volume and a lower resting heart rate (athlete's heart).
