  4. Assess your muscular strength and endurance
  5. Understand the dangers of supplements

Terminology

  • Muscles– organ in the body that causes movement
  • Skeletal Muscle– Responsible for body movement
  • Cardiac MuscleResponsible for the contraction of the heart
  • Muscle Fiber– individual muscle cell
  • Motor unit– a nerve controlling a group of muscle fibers
  • Myofibrils- threadlike structures running the length of the muscle fiber
  • Insertion– point where the muscle is attached to a bone that moves
  • Origin– point where the muscle is attached to a bone that remains in a fixed position
  • Action Potential– the electrical current that cause a muscle to contract
  • Sliding Filament Theory– the theory of how our muscles move
  • Dynamic contraction– muscle movements that cause bodily movements
  • Repetition– One movement pattern
  • Set– a group of repetitions
  • Periodization– Breaking resistance training into different training phases
  • Strength– the maximal amount a force that can produced one time
  • Hypertrophy– muscle fibers getting bigger
  • Atrophy– muscle fibers getting smaller
  • Isokinetic– muscle is contracted at a constant tempo
  • Isometric– muscle contraction that causes no change in muscle length/no bodily movement
