Elite alpine skiers with\n ACL<\/jats:styled-content>\n \u2010\n R<\/jats:styled-content>\n (\n n<\/jats:italic>\n \u2009=\u20099; 26.2\u2009\u00b1\u200911.8 months post\u2010op) and uninjured skiers (\n n<\/jats:italic>\n \u2009=\u20099) participated in neuromuscular screening. Vertical ground reaction force during the\n CMJ<\/jats:styled-content>\n and\n SJ<\/jats:styled-content>\n was assessed using dual force plate methodology to obtain phase\u2010specific bilateral asymmetry indices (\n AIs<\/jats:styled-content>\n ) for kinetic impulse (\n CMJ<\/jats:styled-content>\n and\n SJ<\/jats:styled-content>\n phase\u2010specific kinetic impulse\n AI<\/jats:styled-content>\n ). Dual x\u2010ray absorptiometry scanning was used to assess asymmetry in lower body muscle mass. Compared with controls,\n ACL<\/jats:styled-content>\n \u2010\n R<\/jats:styled-content>\n skiers had increased\n AI<\/jats:styled-content>\n in muscle mass (\n P<\/jats:italic>\n \u2009<\u20090.001), kinetic impulse\n AI<\/jats:styled-content>\n in the\n CMJ<\/jats:styled-content>\n concentric phase (\n P<\/jats:italic>\n \u2009<\u20090.05), and the final phase of the\n SJ<\/jats:styled-content>\n (\n P<\/jats:italic>\n \u2009<\u20090.05). Positive associations were observed between muscle mass and\n AI<\/jats:styled-content>\n in the\n CMJ<\/jats:styled-content>\n concentric phase (\n r<\/jats:italic>\n \u2009=\u20090.57,\n P<\/jats:italic>\n \u2009<\u20090.01) as well as in the late\n SJ<\/jats:styled-content>\n phase (\n r<\/jats:italic>\n \u2009=\u20090.66,\n P<\/jats:italic>\n \u2009<\u20090.01).
