Abstract
Hamstring/quadriceps ratios were assessed on 60 intercollegiate football players at functional speeds of 90, 180, and 300 deg/sec on the Cybex II. The ratio rose as velocity of exercise increased and the quadriceps was stronger than the hamstrings at all speeds. The flexor/extensor ratio differed bilaterally at all speeds with ratio lower for the dominant knee. The study helped establish normative data on hamstring/quadriceps ratios on football players at functional speeds. Furthermore, the ratio provides a guide to observe muscle imbalances which could be a factor in injury. Verf.-Referat
