METHODS
Experimental Approach to the Problem
This study was aimed to statistically analyze multiple 1RM strength qualities of Division-I offensive and defensive American Football linemen. The 1RM strength tests for the back squat and power clean, and vertical jump test will be analyzed in relation to the linear twenty-yard sprint time of Division-I American football offensive and defensive line athletes.
The 1RM squat was used for absolute strength testing, as it is the suggested and widely accepted lower body gold standard test for determining absolute strength (20). The 1RM back squat test was used with the subject’s body weight in pounds to calculate the measurement of relative squat strength, as was done with the power clean. The power …show more content…
Subjects were instructed to precede their jumps with a countermovement. Only two-foot takeoffs were permitted, with no approach steps. The height recorded was the difference between the subjects standing reach and the maximum jump height. Each subject was permitted two jumps to reach their maximum vertical jump height. Instrumentation used for measuring each subject’s vertical jump was the Vertec measurement system, the standard instrumentation that is widely used and accepted for testing vertical jump (Model #22550, Power Systems, Knoxville …show more content…
NSCA 1RM Power Clean protocols were followed. Each subject was required to lift the bar from the floor in one continuous motion and to catch the bar in the rack position in a quarter squat or below. The strength and conditioning staff visually confirmed each rep was caught at that depth or lower. Following the general warm-up, each subject was allowed to perform any necessary amount of warm-up sets and reps prior to reaching their 1RM weight. Weight was added or removed contingent upon the success of the repetition. The greatest successful weight lifted was recorded as the 1RM (lbs.).
