A shorter URL for the above link: . http://tinyurl.com/cyfrrhn . .NEW YORK (Reuters Health) - Women skiers are more likely than men to injure a knee while skiing, and a new study shows they are about twice as likely to have that injury occur to their non-dominant leg, often the left one.
.The study did not go so far as to explain these inequalities, but Dr. Robert Johnson, a sports medicine physician at the University of Vermont College of Medicine said it could be caused "by a whole herd of issues."
."Anatomy, strength patterns, muscle patterns, wider pelvis...it all adds up. It's not just one factor," said Johnson, who was not involved in the research.
.Earlier studies have shown that women are twice as likely as men to hurt a knee during downhill ski crashes, and three times as likely to tear the knee's anterior cruciate ligament, or ACL.
.Gerhard Ruedl, lead author of the new study and a researcher at the University of Innsbruck in Austria, said he was interested in looking at whether women's knee troubles had to do with leg dominance.
. The dominant leg is the one that a person prefers to kick with. . snip .Men were just about equally likely to have injured their left knee as their right, although 87 percent of them were right-leg dominant.
.Most women, 91 percent, were also right-leg dominant, but twice as many injured their left ACL as their right.
. snip .Ruedl said women have greater body asymmetry than men with regard to strength and proprioception, the sense of how the body -- in this case, the knee -- is positioned.
."Studies show that strength and proprioception is greater in the dominant compared to the non-dominant leg," Ruedl told Reuters Health by email.
.This could perhaps make women more vulnerable to the strain that is put on the non-dominant knee as a skier turns.
."During a carving turn the greatest pressure is on the inside edge of the downhill (outside) ski," he said. "Our results showed that most skiers injured their ACL during a right turn where the left leg (= mostly the non-dominant leg) is the outside leg."
