  1. 1Define PhysiologyThe study of how exercise affects the cells and organ systems. The sum of all human physiological responses and adaptations to exercise.
  2. 2What are the systems of the body?NM SCR GIURImmEnd
    Nervous, Muscular, Skeletal, Circulatory, Respiratory, Gastrointestinal, integumentary, urinary, reproductive, immune, endocrine
  3. 3What is GAS?GAS is the general adaptation syndrome which is the process in which your body adapts due to stress placed upon it.
  4. 4What is good stress?eustress – exercise stress.
  5. 5What is bad stress?Distress
  6. 6What is optimum training?the proper quality and quantity of exercise followed by the proper quality and quantity of recovery (sleep, nutrition, lowered stress in the off time)
  7. 7What are the three stages of the General Adaptation Syndrome?Alarm stage, resistance stage, exhaustion stage
  8. 8What are the fundamental cells of the nervous system?Neurons.
  9. 9What do neurons do?They process and transmit information between the central nervous system and the body.
  10. 10What is the central nervous system?The brain and the spine – the control center of the body
  11. 11What is the peripheral nervous system?The PNS sends signals out to organs and muscles and back.
  12. 12What are the two divisions of the peripheral nervous system?Sensory and motor.
  13. 13How does the sensory division function?The sensory division originates from receptors throughout the body that send neurons from a point of stimulus back to the CNS.
  14. 14What are the five primary sensory divisions?Mach Ther NO PHOTO CHEMO
    Machanoreceptors, thermoreceptors, nociceptors, photoreceptors, chemoreceptors
  15. 15How does the motor division function?The motor division originates from the CNS to control actions in the body using motor neurons which run down from the CNS to the muscles and glands (called effectors) that initiate both the muscular and glandular responses, innervating them.
  16. 16What are the two divisions of the motor division?Somatic and autonomic
  17. 17How does the somatic nervous system function?It innervates skeletal muscle to create movement via motor neurons. This is the intentional, voluntary and deliberate firing of neurons to accomplish a task.
  18. 18How does the autonomic nervous system function?The autonomic nervous system performs involuntary actions on internal organs (stomach, lungs, heart)
  19. 19What are the two divisions of the autonomic nervous system?Sympathetic and parasympathetic.
  20. 20How does the parasympathetic nervous system function?The parasympathetic nervous system handles the down time when you recover from eustress. Your heart rate slows, blood goes to internal organs and not to the muscles.
  21. 21Why don’t zebras get ulcers?Short bursts of high stress exercise (sympathetic nervous system) increases the parasympathetic response during rest. The more consistently you exercise, the better the parasympathetic system is able to respond and perform it’s function at rest to recover.
  22. 22What is the law of facilitation?When an impulse passes through a given set of neurons to the exclusion of others, it tends to do so again and each time it transverses the path, the resistance will be smaller.
  23. 23What do progress do beginners experience when first starting to lift weights?The neurological adaptations of the body to the new movements and not an increase in muscular strength.
  24. 24What is the Fitts and Posner Three-Stage Model of Moto Learning?The cognitive, associative, and autonomic phases of learning.
  25. 25What is the cognitive phase of learning?The phase of learning where thinking is required to perform the action. Movement is uncoordinated and relies on visual and verbal cues.
  26. 26What is the associative phase of learning?The phase of learning where there’s greater consistency in replicating the movement with less visual cues and greater proprioception is required.
  27. 27What is proprioception?Proprioception is an awareness of one’s position in space.
  28. 28What is the autonomic phase of learning?The phase of learning where movements are performed flawlessly without thinking about them.
  29. 29Define power. Now, Go.Power is the rate at which work is performed.
  30. 30How is maximum performance determined?Maximum power is determined by mechanical and physiological efficiency. Work output over work input.
  31. 31What are the divisions of motor learning?Motorola Performance and Technique
    Movement pattern, motor skills, motor skill performance, technique, motor learning, and motor control.
  32. 32Movement PatternSeries of anatomical movements that have common elements of spatial segmental movements occurring in the same plane of motion.
  33. 33Motor SkillsActivities or tasks that require voluntary movements of the body to achieve a goal.
  34. 34What does Motor Skill Performance equal?technique +Individual ability +Current External Environment
  35. 35TechniqueBasic movements of any sport or event. May require multiple techniques
  36. 36Motor LearningThe study of the acquisition of motor skills.
  37. 37Motor ControlThe study of how the neuromuscular system functions to activate and coordinate the muscles and limbs involved in the performance of a motor skill.
