Qualitative Torque Analysis

Olympic-style Front Squat Qualitative Torque AnalysisBodybuilding-style Squat Qualitative Torque Analysis

  • Line of gravity positioned over instep
  • Feet push down into floor
    • creates a vertical reactive force moving body and weight upward
  • Examples
    • Olympic-style front squat (diagram 1 above)
      • Barbell positioned infront of body
      • Torso more upright
      • Relatively high knee torque (at bottom position)
    • Bodybuilding-style squat (diagram 2 above)
      • Barbell positioned high on shoulders
      • Torso moderately sloped
      • Torques more moderately distributed between knee and hip
    • Powerlifting-style squat
      • Barbell positioned low behind shoulders
      • Torso highly sloped
      • Relatively high hip torque
    • Box Squat
      • Participant sits back on box
      • Very low knee torque

Other Compound Exercises

  • Torque forces equally distributed through multiple joints
    • Synergistic mechanics
    • Greatest gross force production through true compound mechanics
    • Exposes kinetics chain to particular forces necessary for adaptation
  • Torque forces shifted toward target joints
    • Emphasizes target muscle group or joint movement
    • Decrease torque forces through venerable joint
    • Too great a "torque shift"
    • Subtle torque shifts (if any) may be more beneficial than more drastic torque shifts
      • since greater weights can be used, thereby increasing overall strength performance.
