THE Q-ANGLE AND SPORT

Quadriceps muscle contraction tends to straighten the Q angle. We expe cted that sports comprising a high amount of quadriceps training could be associated with low Q angles. The aim of the present study was to estimate the Q angle in athletes and to investigate its potential asso ciations with participation in sport. Three hundred and thirty-nine at hletes had their Q angle measured. The mean of right-side Q angles was higher than left side, and the mean Q angle was higher in women than in men. The Q angle was positively associated with years of jogging, a nd negatively with years' of soccer, swimming and sports participation at all. It is concluded that the use of Q angle measurements is quest ionable.
