MONDAY, Nov. 7 (HealthDay News) -- Neuromuscular warm-ups may
reduce knee injuries among female high school athletes, a new study
In neuromuscular warm-up, an athlete begins with easy
cardiovascular exercise and progresses to focusing on muscles and
motions used in the sport.
The study included 90 coaches and almost 1,500 female basketball
and soccer players from public schools in Chicago. Half the coaches
were trained in 20-minute neuromuscular warm-up and used that
method with their teams (intervention group) before practices and
games, while the other coaches and their teams used current
standard warm-up methods (control group).
The athletes were followed through the 2006-07 season. There
were 50 lower extremity injuries among the 737 athletes in the
intervention group and 96 lower extremity injuries among the 755
athletes in the control group.
Two lower extremity injuries were suffered by two athletes in
the intervention group and 13 athletes in the control group.
All non-contact lower extremity injuries that required surgery
occurred in the control group.
The study was published in the November issue of the
Archives of Pediatrics & Adolescent Medicine.
"These findings suggest that neuromuscular training should be routine in girls' high school soccer and basketball," Dr. Cynthia R. LaBella, of the Feinberg School of Medicine at Northwestern University in Chicago, and colleagues said in a journal news release.
They noted that injury rates in girls' high school sports are
highest in soccer (2.36 per 1,000 athletes) and basketball (2.01
"Knee injuries are the most common cause of permanent disability in female high school basketball players, accounting for up to 91 percent of season-ending injuries and 94 percent of injuries requiring surgery," the study authors wrote.
Damage to the ACL (anterior cruciate ligament) of the knee,
which is far more common among females than males, is a major
concern, said Dr. Victor Khabie, co-chief of the Orthopedics and
Spine Institute at Northern Westchester Hospital in Mount Kisco,
N.Y. Females may be more susceptible because of the way they land
after a jump, he said.
"Females tend to land with their knees more hyper-extended and somewhat knock-kneed, which theoretically places a great deal of tension on the ACL, leading to tears," he said.
Khabie said he suspects that the neuromuscular warm-up "trains"
female athletes how to jump and land with "better biomechanics,"
thus reducing the risk of an ACL tear.
"More widespread use of this warm-up protocol should be considered by coaches and trainers working with female athletes to help prevent serious knee injuries," Khabie said.
