• C-E-I

  Concentric, Eccentric, Isometric (types of muscle contractions)
• AA


  Agonist and Antagonist (muscle relationship)
• FEAR

  Flexion, Extension, Abduction, Rotation (synovial joint movements)
• FART

  Femur, Arm, Radius, Tibia (major long bones involved in movement)
• Hi VeSSEL

  Heart rate, Ventilation rate, Stroke volume, Systemic circulation, Lactate levels (Immediate Physiological Responses)
• Ventricle and Atrium Vena Cava
• Isometric Contraction:

  • Memory Trick: Think "Isometric = Immobile."
  • Meaning: Muscle stays the same length (no movement).
  • Example: Holding a plank (muscles are working, but there’s no movement).
• . Isotonic Contraction:

  • Memory Trick: Think "Isotonic = In motion."
  • Meaning: Movement happens with the muscle changing length, combining concentric and eccentric.
  • Example: Bicep curl, lifting and lowering the weight (includes both shortening and lengthening).
• Eccentric Contraction:

  • Memory Trick: Think "Eccentric = Elongating."
  • Meaning: Muscle lengthens as it works.
  • Example: Lowering a weight (bicep lengthens as you lower the weight).
• Concentric Contraction:

  • Memory Trick: Think "Concentric = Curling."
  • Meaning: Muscle shortens as it works.
  • Example: Lifting a weight (bicep curl—muscle shortens).
