Basics of Exercise Science
Show Answers:

  1. Physical Activity
    Any bodily movement produced by the contraction of skeletal muscles that increases energy expenditure above resting levels
  2. Exercise
    Planned and structured repetitive movements of physical activity in order to improve or maintain one or more characteristics of physical fitness
  3. Physical Fitness
    • A group of characteristics a person possesses/achieves related to physical activity:
    • Cardioresperatory Fitness
    • Muscle strength
    • Muscle Endurance
    • Flexibility
    • Body Composition
  4. Overload
    Increase in stimulus beyond normal to impose demands on the body system to create adaptation
  5. Threshold
    Minimum amount of overload required to bring about change.
  6. Excessive Overload
  7. Principiles of Training
    • Specificity
    • Progression
    • Overload
    • Reversibility
  8. Specificity
    The body will adapt to specific training stimuli with specific physical and physiological adaptations
  9. Progression
    Incremental increases in workload over period of training
  10. Tissue Adaption/ Remodeling
    • Stimulus creates demand
    • Body repairs/remodels¬†
    • Remodel rate > tissue damage: adaptation occurs
    • Remodel rate< tissue damage: overuse/injury
  11. Muscular strength
    the amount of force a muscle can exert in a single all-out effort (1 Rep Max/1RM)
  12. Muscular Endurance
    Muscle's ability to perform multiple submaximal contractions or hold a static contraction
  13. Flexibility
    Refers to a joint's Range Of Mobility-ROM
  14. Body Composition
    Relative proportion of fat (fat mass) and fat-free (lean mass) tissue in the body.
  15. Cardiorespiratory Fitness
    Ability to perform large muscle, dynamic, moderate to high intensity exercise for prolonged periods of time and reflects the functional capabilities of the heart, blood vessels, blood, lungs and relevant muscles during various exercise demands.
  16. Metabolic Equivalent MET
    • A measure of exercise intensity based on oxygen consumption
    • 3.5 ml*Kg*min
    • <3 Light PhA
    • 3-6 Moderate
    • 6+ Vigorous
  17. Skill-related Fitness Components
    • Agility
    • Coordination
    • Balance
    • Power
    • Reaction Time
    • Speed
