Primary findings indicate that there is ( a ) strong evidence that poor performance on a set distance run for time is a predictor for MSK-I risk in both genders ; ( b ) strong evidence that poor performance on timed shuttle runs is a predictor for MSK-I risk in males ; ( c ) moderate evidence in males and limited evidence in females that poor performance on a timed step test is a predictor of MSK-I risk ; and ( d ) limited or insufficient evidence that poor performance on the Cooper run test , maximal and submaximal aerobic grade d exercise tests , and the Conconi test are predictors of MSK-I risk in males or females or both .
Several measures of CRE are risk factors for training-related MSK-I in military and civilian athletic population s , indicating that CRE may be an important measure for MSK-I risk stratification
A systematic review of the association between physical fitness and musculoskeletal injury risk : part 1—cardiorespiratory endurance .
J Strength Cond Res 31(6 ) : 1744–1757 , 2017—Musculoskeletal injuries ( MSK-Is ) are a significant health problem for both military and athletic population s. Research indicates that MSK-I is associated with physical fitness ; however , the association between specific components of physical fitness and MSK-I in military and athletic population s has not been systematic ally examined .
Step test performance and risk of stress fractures among female army trainees.
BACKGROUND Stress fractures and other musculoskeletal injuries are major sources of morbidity among female military trainees . Several risk factors have been postulated , particularly pre-existing fitness , usually assessed with post-entry run time for ≥ 1.0 mile . PURPOSE Physical fitness is not formally evaluated prior to Army entry . If a valid and simple test that identified women at increased risk of stress fracture were available and could be applied prior to entry , it would facilitate cost-benefit studies of deferral or interventions . These analyses were undertaken to determine if a 5-minute step test conducted before entry identified women at increased risk . METHODS A prospect i ve study was conducted of weight-qualified women entering the Army in 2005 - 2006 , with analyses completed in 2011 . At the pre-entry examination , information was collected on age , BMI , smoking , race , and activity level . Everyone took the step test . All outpatient medical encounters were captured , and stress fractures and other musculoskeletal injuries identified . Women with stress fractures and those with other musculoskeletal injuries were evaluated separately . RESULTS 1568 women were included in the study ; 109 developed stress fractures and 803 other musculoskeletal injury . Women who failed the step test had a 76 % higher stress fracture incidence and a 35 % higher incidence of other musculoskeletal injuries . There was effect modification between age and test failure for stress fracture . CONCLUSIONS A step test that can be administered before military entry identifies women with increased incidence of stress fracture and other musculoskeletal injury . This test could be used pre-entry to defer or target high-risk recruits for tailored fitness training before or after military entrance
