  3. Muscular Endurance
    The ability of a muscle to contract repeatedly over an extended period of time.
  4. Resistance Training
    Controlled and progressive stressing of the body's musculoskeletal system using resistance exercises to build and maintain muscular fitness
  5. Tendons
    The connective tissue attaching muscle to bone
  6. Muscle Fibers
    The cells of the muscular system
  7. Myofibrils
    Thin strands within a single muscle fiber that bundle the skeletal muscle protein filaments an span the length of the fiber.
  8. Slow-twitch muscle Fibers
    Muscle Fiber type that is oxygen dependent and can contract over long periods of time.
  9. Fast-twitch Muscle Fibers
    Muscle fiber type that contracts with greater force and speed but also fatigues quickly.
  10. Motor Unit
    A motor nerve and all the muscle fibers in controls.
  11. Isotonic
    A muscle contraction with relatively constant tension.
  12. Isometric
    A muscle contraction win NO change in muscle length.
  13. Isokinetic
    A muscle contraction with a constant speed of contraction.
  14. Concentric
    A muscle contraction with overall muscle shortening.
  15. Eccentric
    A muscle contraction with overall muscle lengthening.
  16. Hypertrophy
    An increase in muscle cross-sectional area.
  17. One repetition maximum (1 RM)
    The maximum amount of weight you can lift one time.
  18. Spotter
    A person who watches encourages, and, if needed, assists a person who is performing a weight-training lift.
  19. 20 Repetition maximum (20RM)
    The maximum amount of weight you can lift 20 times in a row.
  20. Calisthenics
    A type of muscle endurance and/or flexibility exercises that employs simple movement without the use of resistance other than one's own body weight.
  21. Plyometric exercise
    An exercise that is characterized by a rapid deceleration of the body followed by a rapid acceleration of the body in the opposite direction.
  22. Power
    The ability to PRODUCE FORCE QUICKLY!
  23. Speed
    the ability to rapidly accelerate; exercises for SPEED will Increase stride length and frequency.
  24. Agility
    The ability to rapidly change body position or body direction without losing speed, balance, or body control.
  25. Valsalva Maneuver
    The process of holding one's breath whole lifting heavy weight; this practice can increase chest cavity pressure and result in light-headedness during the lift' excessively increase blood pressure can result after the lift and breath are released.
  26. Ergogenic Aids
    Any nutritional, physical, mechanical psychological or pharmacological procedure or aid used to improve athletic performance.
