BACKGROUND: There is some evidence that functional performance and validated outcome scores differ according to the gender, age, and sport participation status of a patient after anterior cruciate ligament (ACL) reconstruction. However, the impact of these three factors, and interaction among them, has not been studied across a large relatively homogeneous group of patients to better elucidate their impact. QUESTIONS/PURPOSES: We reviewed a large cohort of patients who had undergone ACL reconstruction to determine if ROM, knee laxity, objective performance measures, and validated outcome scores differed according to (1) gender; (2) age; and (3) sport participation status...

Apollo 13 was initially looking like it would be the smoothest flight ever. After the explosion of an oxygen tank however, the astronauts were close to spending the rest of their lives in rotation around the planet. I wished to use this well-known incident to discuss further the link, or lack thereof, between sport sciences research and current field practices. There is a feeling that the academic culture and its publishing requirements have created a bit of an Apollo 13-like orbiting world (e.g., journals and conferences) that is mostly disconnected from the reality of elite performance...

Recent work has espoused the idea that within applied sporting environments, 'fast' working practitioners should work together with 'slow' working researchers. However, due to economical and logistical constraints, such a coupling may not always be practical. Therefore, alternative means of combining research and applied practice are needed. A particular methodology, which has been utilized in recent years, is qualitative research. Examples of qualitative methods include the use of online surveys, one-on-one interviews, and focus groups...
