Movement Asymmetry

Some observed asymmetries may decrease when basic bilateral movement competencies improve. Asymmetrical movement in physical work is considered a positive attribute because it challenges the body in ways programmed exercise does not. A side-to-side difference can coexist with bilateral limitation when both sides are restricted relative to expected movement options. Complete symmetry may not be realistic or necessary because humans naturally show asymmetrical biases. Physical work recruits muscle groups in irregular, asymmetrical patterns unlike the symmetrical movements of structured exercise. Asymmetry can be relevant to injury risk without necessarily impairing performance.
