Common intrinsic risk factors for lower-extremity injuries are previous injury in the same body region and compromised function. 3 , 6 Previously injured athletes often lack the neuromuscular control, balance, proprioception

To evaluate whether a high body mass index (BMI) predisposes marathon/half-marathon participants to lower extremity injuries.


Consenting adult participants at the 2008 National Marathon to Fight Breast Cancer were enrolled in this observational study. The primary outcome measure was prevalence of self-reported lower extremity injury, during both training and race participation, with respect to BMI.


There were 194 subjects with complete data: 139 females (72%) and 55 males. Forty-six percent of females and 51% of males ran the full marathon (P = .63). Median BMI was 23.7 kg/m2 for females and 26.2 kg/m2 for males (P = .001). Eleven (24%) females in BMI tertile 1 (T1) suffered a training injury, while 9 (18%) from T2 and 4 (9%) from T3 suffered injuries (P = .072; OR 0.89; 95% CI 0.78 to 1.01). Twenty-six (19%) females suffered an injury during the race. Females in T1 were more likely to suffer a race-related injury (P = .038; OR 0.87; 95% CI 0.77 to 0.99). Females were 13% less likely to suffer a race-related injury with each 1-unit increase in BMI. Rates of injury did not differ by BMI tertile in males.


A high BMI did not impart an increased risk of lower extremity injury during training or race participation.

Lower extremity injuries in women’s basketball players are generally presented as seasonal team incidence. Available data were reported by team athletic trainers to overseeing bodies yielding estimates of injury rates as a percentage of all injuries sustained. By summarizing career incidence of women’s basketball players’ injuries, a new perspective indicating potential risk of injury can be considered.


To summarize the career incidence of lower extremity injuries in intercollegiate and professional women’s basketball players, examine the effect of anterior cruciate ligament (ACL) injury on professional basketball players’ career longevity, and explore the relationship between ankle sprains and knee injuries in this population.




246 elite-level women’s basketball players.

Outcome Measures:

Career incidence of lower extremity injury, professional career length, relationship between history of ankle sprain and ACL injury frequency calculations, and chi-square statistics. Results: Seventy-four of 85 (87.06%) professional Women’s National Basketball Association (WNBA) and 172/179 (96.09%) available collegiate Big East Conference (BEC) women’s basketball players completed the survey. Ankle sprains were the most frequently reported injury with 170/246 (69.11%) participants indicating at least one during their career. Patellar tendinopathy (28.46%), meniscal injury (22.76%), and ACL tear (21.54%) were also common. Professional career length in participants with an ACL reconstruction averaged 6.11 ± 3.20 seasons, more than the 5.70 ± 4.17 seasons reported by those without an ACL injury. Professional participants who did not report an ankle sprain were more likely to report an ACL tear (χ2 = 10.96; p = .000932).


Summarizing career incidence provides a new perspective of women’s basketball players’ injuries. Ankle sprains and knee injuries were commonly reported, both more frequently than by traditional research methods. These data may assist in developing injury prevention and rehabilitation strategies for injured athletes.

Lower extremity injuries are common among the physically active population. 1 Over 50% of all injuries in collegiate athletes that occur in practices or games involve the lower extremity. 1 Among lower extremity injuries, ankle sprains account for approximately 14% and 23% of all collegiate and

Concussions are a significant problem in athletic populations and can cause several severe symptoms. 1 Studies have shown that athletes who suffer concussions often have persistent postural stability deficits. 1 Long-term effects include an increased risk of lower-extremity injury, 2
