Background Stress fractures account for substantial morbidity for young women undergoing U.S. Marine Corps basic training. Hypothesis Certain pretraining characteristics identify women at increased risk of stress fractures during boot camp. Study Design Cohort study; Level of evidence, 2. Methods Data collected included baseline performance on a timed run (a measure of aerobic fitness), anthropometric measurements, and a baseline questionnaire highlighting exercise and menstrual status among… Expand
Epidemiology of stress fracture and lower-extremity overuse injury in female recruits.
TLDR
The results suggest that stress fracture injury might be decreased if women entered training with high aerobic fitness and participated frequently in lower-extremity strength training. Expand
Determinants of stress fracture risk in United States Military Academy cadets.
TLDR
Although prior physical training in men, length of prior estrogen exposure in women and leg bone dimensions in both genders played a role, these factors play a minor role in the development of stress fractures in physically fit USMA cadets. Expand
Step test performance and risk of stress fractures among female army trainees.
TLDR
A step test that can be administered before military entry identifies women with increased incidence of stress fracture and other musculoskeletal injury and could be used pre-entry to defer or target high-risk recruits for tailored fitness training before or after military entrance. Expand
Prospective cohort study of the risk factors for stress fractures in Chinese male infantry recruits
TLDR
This prospective, cohort study indicates that fracture history, lower exercise level and GDF5 rs143383 may be predictive risk factors for stress fractures in Chinese male infantry recruits. Expand
Femoral neck stress fracture in Air Force basic trainees.
TLDR
In this study body mass index was not correlated with FNSF risk; however, physical fitness level on arrival to training and female gender were significantly associated with risk of F NSF. Expand
Factors associated with discharge during marine corps basic training.
This prospective study assessed risk factors for discharge from basic training (BT) among 2,137 male Marine Corps recruits between February and April 2003. Physical and demographic characteristics,Expand
Development of a Prediction Model for Stress Fracture During an Intensive Physical Training Program: The Royal Marines Commandos
TLDR
Although 25(OH)D and VO2max had only a borderline statistically significant association with SF, the inclusion of these factors improved the performance of the model, and will assist in identifying recruits at greater risk of SF during training. Expand
High‐Risk Stress Fractures: Diagnosis and Management
TLDR
Treatment of high‐risk stress fractures consists of nonweight‐bearing immobilization, often with a prolonged period away from sport, and a more methodic and careful reintroduction to athletic activity. Expand
Effect of cardiovascular and muscular endurance is not associated with stress fracture incidence in female military recruits: a 12-month follow up study
TLDR
In the present female cohort, physical activity prior to recruitment had no protective effect against SF during or after ABT, and SFs were not correlated to these variables at the end of the ABT program and 16 months after recruitment. Expand
Flexibility as risk factor for stress-fracture development in South African male soldiers
TLDR
Although normal ankle and limited hip external flexibility do not appear to predispose these male soldiers to stress fracture development these variables should not be excluded as possible intrinsic risk factors. Expand

The Impact of Lifestyle Factors on Stress Fractures in Female Army Recruits
TLDR
It is concluded that prevention of stress fractures in female military recruits should include a thorough assessment of lifestyle factors such as exercise patterns, alcohol and tobacco habits, and corticosteroid and DMPA use. Expand
Stress fractures of the pelvis in female navy recruits: an analysis of possible mechanisms of injury.
TLDR
Self-reported fitness, activities before recruit training, or a history of amenorrhea was not found to be associated with the development of a pelvic stress fracture in the female Navy recruits studied. Expand
Risk Factors for Stress Fractures in Track and Field Athletes
TLDR
The results suggest that it may be possible to identify female athletes most at risk for this overuse bone injury, and multiple logistic regression revealed that age of menarche and calf girth were the best independent predictors of stress fractures in women. Expand
Risk factors associated with stress reactions in female Marines.
TLDR
It is concluded that an increased subtalar joint range of motion is not a risk factor for stress reactions in women, and further studies with a larger study population should be performed to confirm these findings. Expand
Stress fractures in female army recruits: implications of bone density, calcium intake, and exercise.
TLDR
Stress fracture in female Army recruits was not correlated with bone density or calcium intake during adolescence, although a weak relationship to prior physical activity was observed. Expand
Stress fracture in military recruits: gender differences in muscle and bone susceptibility factors.
TLDR
In both genders, differences in fitness, muscle, and bone parameters suggest poor skeletal adaptation in fracture cases due to inadequate physical conditioning prior to training. Expand
Epidemiology and site specificity of stress fractures.
TLDR
Although a gender difference in rates is clearly evident in military populations, this is less apparent in athletes, and available data suggest that runners and ballet dancers are at relatively high risk for stress fractures. Expand
Factors associated with stress fracture in young army women: indications for further research.
TLDR
Current smoking, previous history of amenorrhea, and known family history of osteoporosis were significantly associated with self-reported stress fracture history, while black ethnic origin was a protective factor. Expand
Use of simple measures of physical activity to predict stress fractures in young men undergoing a rigorous physical training program.
TLDR
It is suggested that risk of stress fracture during rigorous physical training is increased by poor physical fitness and low levels of physical activity prior to their entry into the program. Expand
The relation between stress fractures and bone mineral density: evidence from active-duty Army women.
TLDR
Femoral neck BMD was significantly associated with the probability of stress fractures, and Optimal training programs should balance the beneficial indirect effect of increased exercise (through increased BMD) with its detrimental direct effect on stress fractures. Expand
