Te. Hewett et al., The effect of neuromuscular training on the incidence of knee injury in female athletes - A prospective study, AM J SP MED, 27(6), 1999, pp. 699-706
To prospectively evaluate the effect of neuromuscular training on the incid
ence of knee injury in female athletes, we monitored two groups of female a
thletes, one trained before sports participation and the other not trained,
and a group of untrained male athletes throughout the high school soccer,
volleyball, and basketball seasons, Weekly reports included the number of p
ractice and competition exposures and mechanism of injury, There were 14 se
rious knee injuries in the 1263 athletes tracked through the study. Ten of
463 untrained female athletes sustained serious knee injuries (8 noncontact
), 2 of 366 trained female athletes sustained serious knee injuries (0 nonc
ontact), and 2 of 434 male athletes sustained serious knee injuries (1 nonc
ontact). The knee injury incidence per 1000 athlete-exposures was 0.43 in u
ntrained female athletes, 0.12 in trained female athletes, and 0.09 in male
athletes (P = 0.02, chi-square analysis). Untrained female athletes had a
3.6 times higher incidence of knee injury than trained female athletes (P =
0.05) and 4.8 times higher than male athletes (P = 0.03). The incidence of
knee injury in trained female athletes was not significantly different fro
m that in untrained male athletes (P = 0.86), The difference in the inciden
ce of noncontact injuries between the female groups was also significant (P
= 0.01). This prospective study demonstrated a decreased incidence of knee
injury in female athletes after a specific plyometric training program.
