Muscle Tightness: Cause or Symptom?

by Greg Roskopf |  Date Released : 19 Apr 2005

  • Introduction – a question of research. Where’s the scientific substance of stretching?
  • ACSM stretching positioning statement 2002 – Performance? Injury prevention?
  • Answer for today’s trainers?
    • Must recognize that there maynot be a benefit
    • Must look for an alternative
  • Greg's experience with stretching after having a severe injury
    • Increased symptoms
    • Various injuries
  • Why do muscles tighten up?
  • Walking on ice
  • Is muscle tightness a cause or a symptom?
  • What are we doing as an industry?
  • Understanding the sensory receptors and their function
    • Muscle spindle: acvtivation
    • Golgi tendon organ: inhibition
  • Strength coach contradiction: goal of strength training: to increase recruitment of motor units (muscle spindle override golgi tendon) vs. Goal of stretching: to calm down the muscle spindle
  • What is the effect?
  • Muscle Spindle
  • Normal vs abnormal input
  • Feed back loop of the muscle spindle: causing muscle contraction and opposite inhibition
  • If Abnormal feedback: lose loop, lose inhibition cause tightness
  • How to increase ROM – don’t create mobility with out stability
  • Training in extremes of motion
  • Reciprocal inervation
  • Tightness is secondary to lack of neural input
  • Activate muscles on opposite side – causes inhibition of tight muscles - increased ROM
  • Conclusion: Stretching? We don’t know the truth
  • Find alternative approach + create checks and balances - never increase mobility without increasing stability
