Asymmetries of the lower limb: the calculation conundrum in strength training and conditioning

Asymmetry detection has been a topic of interest in the strength and conditioning (S&C) literature with numerous studies proposing many different equations for calculating between-limb differences. However, there does not appear to be a clear delineation as to which equation should be used when quantifying asymmetries. Consequently, the authors have uncovered nine different equations which pose confusion as to which method the S&C specialist should employ during data interpretation. This article aims to identify the different equations currently being used to calculate asymmetries and offer practitioners a guide as to which method may be most appropriate when measuring asymmetries
