ABSTRACT

RELATIONSHIPS OF A POWER COEFFICIENT, ANTHROPOMETRIC MEASURES, AND PERFORMANCE CHARACTERISTICS TO VELOCITY FROM A FOOTBALL STANCE

By Jerome Michael Learman

 The purpose of this study was to examine the relationships between various physical parameters (sprint speed, leg strength, sitting height, body weight, standing height, and arm length) in offensive and defensive linemen and their ability to quickly move three yards from a three-point stance to a blocking dummy. Data collected on each subject were of three types: personal, anthropometric, and performance. Personal data was collected by having the participants fill out a personal information sheet. The anthropometric data were collected with three devices: a free standing anthropometer, a standard scale, and a modified anthropometer. The performance data collected was the 40-yard dash, leg strength, and blocking speed over three yards. The equipment used to collect this data was a Zen-on Metrina Multi stop watch, a squat rack, and the Ariel Performance Analysis System (APAS). An analysis of data on speed from a three-point football stance found that four variables had a significant (p < .05) correlations with time over three-yards from a three-point stance: power coefficient (r = -.22), subjects’ grade level in school ( r = -.37), number of years subjects played football in high school (r = .-34), and playing level (r = -.34).
