To investigate sprinting strategy, acceleration and velocity patterns were determined in college football players (n = 61) during performance of a 9.1-, 36.6-, 54.9-m sprints. Acceleration at 9.1-m intervals each sprint. Lower-body strength power evaluated by 1 repetition maximum (1-RM) squat, clean, jerk, vertical jump, standing long triple jump. Sprint times averaged 1.78 +/- 0.11 seconds (9.1 m), 5.18 0.35 (36.6 7.40 0.53 seconds. peaked 9.1 m (2.96 0.44 x s(-2)), was held constant 18.3 (3.55 0.0.94 negative 27.4 (-1.02 0.72 s(-2)). Velocity (8.38 0.65 s(-2)) decreased slightly, but significantly (7.55 0.66 associated with the acceleration. Measures lower-body related to acceleration, velocity, sprint only when corrected for body mass. strength/BM correlated highest 36.6-m time (rs -0.55 -0.80) (strength r 0.67-0.49; 0.73-0.81) 0.68-0.53; 0.74-0.82) m. per mass lower lineman compared linebackers-tight ends backs. The same position group, differences magnitude is rapid increase (through m) high maintained throughout independent played. best performances (independent distance) appear be initial attained velocity. Strength relative appears impact contribution performance.
