Abstract: PURPOSE/HYPOTHESIS: The purpose of this study was to determine if any differences exist between hamstring to quadriceps ratios of offensive and defensive NCAA Division III football players. The research hypothesis was that a difference in hamstring to quadriceps strength ratios would exist between positions, with defensive players having higher hamstring to quadriceps strength than the offensive players. MATERIALS/METHODS: Thirty-five subjects from one NCAA Division III collegiate football team participated in this study. Exclusion criteria included any kne injury sustained in the last 6 months and any health contraindications to exercise. Subjects were also screened for incidence of lower extremity or back injury in the last months. Each subject gave informed consent and completed a demographic intake for prior to participation. A Cybex Norm isokinetic dynamometer was used to access hamstring and quadriceps strength of the players. Testing began with a 5-minute wan up on a cycle ergometer. Each subject then performed 4 trial repetitions followed by t repetitions at 60 deg/sec, 180 deg/sec, and 300 deg/sec. Players were assigned to one the two groups based on their positions: offense(n=16) and defense(n=19). Statistical analysis was performed on the highest recorded torque for each speed. An independent samples t test was used to test the null hypothesis and to analyze the data collected on comparing hamstring to quadriceps ratios in the offensive versus defensive players. The results were reported a Means and Standard Deviations (M ±SD). Statistical significance was set at a p value

Book Description
It is over 25 years since isokinetic dynamometry was first introduced into clinical practice and exercise science. Physical therapy, in particular, has benefited significantly from this technology, which rapidly became the tool of choice in hundreds of research papers as well as the cornerstone of quantitative muscle performance assessment in the clinical setting. About 1984, the technology behind isokinetic dynamometry made considerable progress when computers were incorporated to control the hardware, that is the integral power sources and the on-line processing of mechanical signals. This enabled users to establish a common basis for carrying out eccentric contractions and to obtain comprehensive information on muscle strength immediately. This book does not pretend to cover all the topics that have been examined under isokinetics. Nor is it intended to be a quick and superficial introduction to clinical applications. Rather, it is aimed at those who have at least some experience and are at a stage where they are beginning to ask some very serious questions and would not necessarily be happy with very simple answers.
