What is the primary fuel source during low-intensity, long-duration aerobic exercise?
Answer: Fat (triglycerides)
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.
Which cardiovascular exercise modality is generally considered the lowest impact on the joints?
Answer: Swimming or water aerobics
Swimming and water aerobics are the lowest impact on joints because water buoyancy reduces gravitational stress on the musculoskeletal system significantly.
Cardiac output is defined as:
Answer: Heart rate multiplied by stroke volume
Cardiac output equals heart rate multiplied by stroke volume, representing the total volume of blood the heart pumps per minute.
Heart rate drift during prolonged steady-state exercise is primarily caused by:
Answer: Dehydration reducing plasma volume and cardiovascular drift
Cardiovascular drift occurs during prolonged exercise as dehydration reduces plasma volume, causing heart rate to rise in order to maintain adequate cardiac output.
The specificity principle states that:
Answer: Physiological adaptations are specific to the type, speed, and pattern of training performed
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.
Which of the following best defines interval training?
Answer: Alternating between periods of higher-intensity effort and lower-intensity recovery
Interval training alternates between periods of higher-intensity effort and recovery (lower intensity or rest), allowing greater total training volume at higher intensities than continuous training.
For a previously sedentary, deconditioned client beginning cardiovascular training, which approach is most appropriate?
Answer: Start with 10–20 minutes of low-to-moderate intensity exercise 2–3 days per week
Deconditioned clients should begin with 10–20 minutes of low-to-moderate intensity exercise 2–3 days per week, then progressively increase duration and frequency as fitness improves.
