NASM VIRTUAL COACHING CHAPTER 7 QUESTIONS AND ANSWERS

The autonomic nervous system is comprised of which two primary branches? Sympathetic and parasympathetic What is the primary difference between a gyroscope and accelerometer? A gyroscope can measure rotational movement, whereas an accelerometer can only measure movement and acceleration in the three-axis plane What is the term for an abnormally low concentration of oxygen in the blood? Hypoxemia How does an electrocardiogram (ECG) sensor collect data? Direct measurement of the heart's electrical activity What are the most common units of measurement for heart rate variability? milliseconds (ms) Which is the following is an example of a biometric? Heart rate variability How should a fitness professional determine which wearable technology to integrate into their virtual coaching business? Select an appropriate device after conducting research into which devices have been clinically validated versus gold standard medical equipment What is the gold standard method for collecting heart rate data? Electrocardiography Approximately what percentage of U.S. adults have insufficient sleep? 33% Oxygen is transported via a protein molecule in the red blood cells. What is the name of this protein molecule? Hemoglobin What is the normal range for resting heart rate in adults? 60 to 100 bpm After establishing a baseline, the fitness professional determines that it takes Client B greater than 45 minutes to fall asleep each evening. What term is used to describe the amount of time required to fall asleep? Sleep latency Which of the following lifestyle habits is most likely to reduce resting oxygen saturation? Smoking Which of the following is an example of positive reinforcement? Recognizing a client for improvements in heart rate variability Which sleep stage and type represents the lowest heart rate and respiratory rate? Stage 3 (non-REM) Which of the following may be an effective tool for measuring cumulative physical fatigue in overtrained athletes? Decreased heart rate variability What type of interventions should take place during the baseline phase? None In general, what type of biometric trend is favorable, indicating an improvement in stress resilience and physical and mental health? A steady increase in HRV over time What is the term for a resting heart rate lower than 60 bpm? Bradycardia After establishing a baseline, a fitness professional recognizes a significant decrease in heart rate variability, elevated heart rate, and inadequate sleep duration. What type of training modifications should the fitness professional consider? Modify the program to focus on active or passive recovery What type of exercise may lead to a decrease in resting heart rate in healthy clients? All types of exercise may lead to a decrease in resting heart rate in healthy clients What are the cons of utilizing wearable technologies with more advanced features? They are often more expensive and increase the complexity of use
