  1. Types of Muscle Contractions How Muscles Generate Force A REALLY bad Cramp Pushing the Wall Bicep Curl Landing from a high place

  2. Twitch Contractions • A quick, jerky response to a stimulus • Play a minimal role in normal muscle activity

  3. Produced by a series of stimuli bombarding the muscle in rapid succession Contractions melt together andresult in a sustained contraction or tetanus A BAD Cramp Tetanic Contraction

  4. The muscle if fired against a load, but DOES NOT Shorten or Lengthen Fires at a constant Length Carrying an object in front of you without dropping it Isometric

  5. A muscle firing against a load Shortenscausing movement at the joint Isotonic Resistance through most of the ROM Resistance decreases after a certain point Gravity Assists Isokinetic Resistance through the full ROM Concentric

  6. Muscle fibers are lengthening WHILE they are firing Controlling Movement Lowering a heavy weight Landing from a jump Decelerating Eccentric
