Abstract

The purpose of this study was to collect descriptive functional Hamstring to Quadriceps (H:Q) ratio data, as defined by Aagaard, Simonsen, Magnusson, Larsson, and Dyhre-Poulsen (1998), and determine if differences exist in the functional H:Q ratio between Division I-AA college football athletes that are in different years of athletic eligibility. The primary research hypothesis was that there would be a statistically significant difference across the different years of eligibility. The population tested included 47 male Division I-AA college football players between the ages of 18-23. The functional H:Q ratio for extension was executed on the Biodex System 3 Pro (Shirley, New York) isokinetic dynamometer at 60, 180, and 270 degree per second for the left and right legs. The concentric quadriceps peak torque was then divided into the eccentric hamstring peak torque to obtain the functional H:Q ratio for extension. There was no significant difference noted between the functional H:Q ratio and year of athletic eligibility. This may be due in part to the fact that the strength program at this university focuses primarily on the concentric motions with regards to the quadriceps without eccentrically strengthening the hamstrings.
