Context: Nearly 51 million Americans chose running as their primary form of exercise in 2012. However, with participation in running comes an increase in risk for sustaining a running related musculoskeletal injury (RRMI), with prevalence as high as 79%. It is estimated females sustain approximately 54% of all RRMI. Runners with a RRMI often exhibit with altered running kinematics, an imbalance in hip flexibility, and decreased hip strength. Tests such as the Star Excursion Balance Test (SEBT) and Single Leg Hop for Distance (SLHD) have been used within athletic populations to identify individuals at an increased risk of injury; however these tests have not been applied to the recreational running population. Objective: To determine baseline differences in running kinematics, hip strength and range of motion, and clinical screening tests between female runners who do or do not sustain a RRMI during a 16-week formalized training program. Design: Prospective cohort study. Setting: Research Laboratory. Patients or Other Participants: Fifty-four healthy female participants (38.75+9.6yrs, 1.66+0.07m, 66.29+13.2kg) enrolled in a 16-week formalized marathon running program volunteered. Interventions: All participants performed all assessment tests at one baseline testing session. The testing order was randomized and performed bilaterally. Running kinematics was collected using a 3D motion capture system; value of interest was hip flexion angle at initial contact of stance phase. The SEBT in the anterior reach (SEBT-A), was normalized by true leg length and reported as a percentage. The SLHD was normalized by height and expressed as a percentage. Hip flexion and extension active range of motion (AROM) were measured using a standard goniometer and reported in degrees. Hip flexion and extension strength were measured using a hand held dynamometer, and were normalized and reported as torque per kilogram of body mass (Nm/kg). At the conclusion of the program, all participants were designated into either the RRMI (RRMI) or injury-free (INJF) group. A RRMI was a musculoskeletal injury of the lower extremity that occurred as a result of running, and resulted in the modification or removal of running for at least one training day. Main Outcome Measures: The independent variable was group (RRMI, Injury-free), and the dependent variables were hip flexion angle at initial contact, SEBT-A, SLHD, hip flexion and extension AROM, and hip flexion and extension torque. Scores of the injured limb was compared to the mean of the scores of injury free group. Independent t-tests with a Bonferroni Correction were used for each dependent variable; alpha was set a-priori at (p<0.05). Results: There were no significant differences between RRMI and INJF in hip flexion angles (RRMI: 25.27 + 4.79o ; INJF: 27.80 + 4.79o; p=0.14), SEBT-A (RRMI: 63.56 + 4.73%; INJF: 63.98 + 5.39%; p=0.78), SLHD (RRMI: 37.50 + 11.31%; INJF: 34.37% + 9.31%; p=0.29), hip flexion (RRMI: 73.33 + 12.16o; INJF: 75.07 + 12.37o; p=0.63)or extension (RRMI: 15.09 + 5.40o; INJF: 15.86 + 4.88o; t(52)= -0.51, p=0.61) AROM, hip flexion (RRMI: 0.78 + 0.13nm/kg; INJF: 0.74 + 0.17nm/kg; p=0.38)or extension (RRMI: 0.71 + 0.14nm/kg; INJF: 0.68 + 0.19nm/kg; p=0.55). Conclusions: Baseline sagittal plane hip angles at initial contact, AROM, and strength measurements are not different between runners sustaining a RRMI and those injury-free during training. Future research should focus on what batteries of clinical functional screening tools are most appropriate for running populations.
