30 Seconds Summary
Research Spotlight: Ankle mobility affects squat forward lean more than femur length

  • Improving ankle mobility can significantly reduce forward lean in squatting, more so than altering body segment ratios.
  • A 2017 study found that ankle dorsiflexion mobility is a major factor influencing forward lean, explaining 45% of its variance.
  • Additional body segment lengths like trunk-to-thigh and thigh-to-shank ratios add little predictive value to forward squat lean when combined with dorsiflexion mobility in a model.
  • Using heel-raised shoes or adopting a slightly wider stance with greater hip abduction might also help in achieving a more upright squat posture.
