Strength and power are vital to American football players and training of these variables is constant in sophisticated, year-round preparation supervised by strength and conditioning specialists. The drive block is a principal technique in offensive line play and the squat exercise, a major staple for lower body training, is thought to relate to leg power in the task of “firing-off the line”. PURPOSE: The purpose of this study was to investigate the relationship of power (AP) and velocity (AV) to body mass (BM), fat and the 1-RM squat. METHODS: Following IRB approval 18 offensive linemen performed 10 fire-outs from a three-point stance into a stationary blocking dummy while assessments of power and velocity were made. Power (Watts) and velocity (m/sec) was recorded using a Tendo® Power and Speed Analyzer and these data were correlated with each players’ body mass, fat, and 1-RM squat. RESULTS: Means for each variable were: BM 193.82 +33.41kg, 1-RM squat 208.97 +35.93kg, fat 25.45 +6.1%, AP 1442.53 +137.46 Watts, AV 1.079 +0.09 m/sec. Correlations of the variables yielded significant (pCONCLUSION: Based on these results training protocols inclusive of squats positively relates and body fat negatively contributes to offensive line play. It is suggested that players include the squat in year-long training and attempt to replace fat by lean mass in order to maximize playing efficiency.
