OBJECTIVE: To evaluate the influence of previously treated, though clinically resolved, lower extremity injury on performance in a timed 20-meter shuttle run.
DESIGN: Case control study.
SETTING: National Collegiate Athletic Association (NCAA) Division I college during the 2000/2001 preparticipation physicals.
PARTICIPANTS: NCAA Division I athletes (n = 213) participated in this research study. Athletes were excluded if they presently had an unresolved lower extremity injury or low back pain.
MAIN OUTCOME MEASURES: Time to complete a 20-meter shuttle run was recorded. Previous lower extremity injury and college year were recorded via a short questionnaire.
RESULTS: A significantly slower response time on the 20-meter shuttle run was observed in freshman athletes with a history of a lower extremity injury, as compared with freshmen without a previous injury (p = 0.01). No significant difference was noted in non-freshman collegiate athletes regardless of injury history (p = 0.98).
CONCLUSION: Kinetic chain deficits may exist long after symptomatic recovery from injury resulting in functional deficits, which may be missed on a standard physical assessment. The slower shuttle run times observed in freshmen with previous lower extremity injury may be a manifestation of insufficient treatment received at the high school level or the benefit of a mandatory core strengthening program in returning athletes. Further study is necessary to identify and validate the cause-and-effect relationship.
CLINICAL RELEVANCE: This study may support residual functional deficits in incoming college athletes, which may be related to inadequate care in the high school setting.
