Task: Answer Verification
Input (English): Question: Are isokinetic concentric quadriceps and hamstring strength variables from the NFL Scouting Combine predictive of hamstring injury in first-year professional football players?
Answer: Isokinetic strength data collected from collegiate players at the NFL Scouting Combine were not useful for predicting risk of hamstring injury in subsequent professional NFL competition. These data call into question commonly accepted assumptions about risk factors for hamstring injury, at least for elite collegiate American football players, when the temporal relationship between Cybex testing and actual injury is several months.
Output (English): no
