Sample Questions
A personal trainer is explaining to a client how the body coordinates movement during exercise. According to NASM, which system is responsible for collecting, processing, and responding to information from the environment?
- A. The cardiovascular system
- B. The endocrine system
- C. The nervous system
- D. The digestive system
NASM defines the nervous system as the system responsible for collecting, processing, and responding to information from the environment.
A personal trainer is studying the two major divisions of the nervous system. According to NASM, which structures make up the central nervous system?
- A. The spinal nerves and cranial nerves
- B. The brain and spinal cord
- C. The sympathetic and parasympathetic pathways
- D. The sensory neurons and motor neurons
NASM identifies the central nervous system as consisting of the brain and spinal cord.
A personal trainer reviews how the nervous system influences exercise performance. According to NASM, which two major divisions make up the nervous system?
- A. The somatic and autonomic nervous systems
- B. The central nervous system and the peripheral nervous system
- C. The sympathetic and parasympathetic nervous systems
- D. The sensory nervous system and the motor nervous system
NASM identifies the two major divisions of the nervous system as the central nervous system and the peripheral nervous system.
A client asks how their brain communicates with their muscles during a squat. According to NASM, what is the primary function of the central nervous system?
- A. To transport oxygenated blood to working muscles during physical activity
- B. To produce hormones that regulate muscle growth and recovery after exercise
- C. To act as the command center for collecting and interpreting sensory information and sending motor commands to muscles
- D. To generate the mechanical tension required for all voluntary and involuntary muscle contractions
NASM describes the CNS (brain and spinal cord) as the command center for interpreting sensory information and coordinating motor output to muscles.
A personal trainer explains to a client that some nerves carry signals toward the brain while others carry signals away from it. According to NASM, the peripheral nervous system serves which two essential communicative functions?
- A. Carrying only motor commands from the spinal cord to muscles and joints
- B. Generating and storing electrical impulses for emergency fight-or-flight responses
- C. Filtering all sensory input before passing only relevant signals to the central nervous system
- D. Carrying sensory information to the CNS and delivering motor commands from the CNS to muscles and organs
NASM describes the peripheral nervous system as carrying sensory information to the CNS and delivering motor commands from the CNS to muscles and organs, the two essential communicative functions.
During a functional movement assessment, a personal trainer considers how the nervous system integrates with muscles and bones. According to NASM, what does the nervous system collectively allow the human movement system to do?
- A. Provide structural support and leverage for all external resistance activities
- B. Generate energy exclusively through anaerobic pathways during high-intensity performance
- C. Communicate, control, and coordinate the functions of the muscular and skeletal systems during movement
- D. Regulate macronutrient absorption and redistribution during prolonged exercise
NASM states the nervous system allows the human movement system to communicate, control, and coordinate all of the functions of the muscular and skeletal systems.
A personal trainer is explaining the difference between the CNS and PNS when a client asks what happens when they decide to begin a squat. According to NASM, which structures are responsible for processing that decision and relaying it to the peripheral system?
- A. Sensory neurons in the skin and muscle receptors
- B. The Golgi tendon organs and muscle spindles within the working muscles
- C. Peripheral nerves that exit the spinal cord and travel to the lower extremities
- D. The brain and spinal cord, the two components of the central nervous system
NASM identifies the brain and spinal cord as the central nervous system, the structures that process the volitional decision and relay commands to the periphery.
A fitness professional is explaining to a client why improving neuromuscular coordination is essential to optimizing performance. According to NASM, which statement most accurately reflects the nervous system's integrative role in human movement?
- A. The nervous system provides structural stability to joints through ligamentous tension generated by motor nerve activity
- B. The nervous system stores and releases chemical energy for muscle contractions during high-intensity exercise
- C. The nervous system generates the primary mechanical force that moves bones through their range of motion
- D. The nervous system collects, processes, and responds to information, allowing the human movement system to communicate, control, and coordinate all muscular and skeletal functions
NASM describes the nervous system as responsible for collecting, processing, and responding to information, allowing the human movement system to communicate, control, and coordinate all functions of the muscular and skeletal systems.
Key Terms in This Domain
- Muscle fiber types: Type I (slow oxidative, fatigue-resistant, low force), Type IIa (fast oxidative-glycolytic, intermediate), Type IIx (fast glycolytic, high force, fatigues fast)
- Muscle contractions: Concentric (shortening), eccentric (lengthening under load), isometric (no length change); eccentrics produce the most force and the most DOMS
- All-or-none principle: A motor unit either contracts fully or not at all; force is graded by recruitment and rate coding
- Length-tension relationship: A muscle generates maximal force at its resting (optimal) length; over- or under-shortened positions reduce force production
- Force-couple relationship: Muscles work as synergistic groups producing rotational forces around a joint (e.g., glute med + TFL + adductors at the hip)
- Cardiorespiratory system: Heart, lungs, and blood vessels deliver O₂ and remove CO₂; trained pulse pressure widens, stroke volume rises, resting HR falls
- Overhead Squat Assessment: NASM's primary dynamic posture screen: identifies muscle imbalances by checkpoint (feet, knees, LPHC, shoulders/head)
- Resistance training systems: Single-set, multiple-set, pyramid, superset, complex, drop set, giant set, tri-set, vertical/horizontal loading, split routine, peripheral heart action
- Skeletal system roles: Support, protection, movement (lever system), mineral storage (Ca, P), blood cell formation (hematopoiesis)
- Sliding filament theory: Actin and myosin slide past each other when calcium binds troponin and exposes binding sites, the molecular basis of muscle contraction
