Football--Training; Motor ability--Testing;


The main purpose of this study was to examine the effects of the RS (lateral rhythm step) on the pro-agility test and observe how it compares with the crossover step (CS). Thirteen Division I college football players were recruited to perform both step techniques which were randomly assigned to them. Each technique was performed twice for a total of four trials. A high-speed camera was used to record all trials at 100 Hz. All videos were then digitized and analyzed to determine maximum acceleration (amax), time to maximum acceleration (tamax), body angle (θlean), time to reach body angle (Tθlean), and times during the first five yards (t1), the second ten yards (distance covered immediately after the first five yards) (t2), the last five yards (t3), and the total time (tT) of the drill.

Descriptive statistics (mean ± SD) were calculated for all variables. Alpha was set at (p<0.05) for all tests. A significant difference between the two techniques was observed at t1 (RS mean 1.56 ± 0.09 s, CS mean 1.62 ± 0.11 s), ttotal (RS mean 4.99 ± 0.35 s, CS mean 5.09 ± 0.35 s), and tamax (RS mean 0.38 ± 0.67, CS mean 0.46 ± 0.61). It appears that the RS allowed for the utilization of the SSC more effectively, which contributed to the production of higher force during the beginning, as well as the end of t1. Additionally, the Tθlean, although not very significant (p=0.06), it demonstrates a trend in favor of the RS. Overall, the RS appeared to be superior to the CS for reaching peak acceleration faster during the initial phase of the pro-agility drill as well as short distance sprints that are initiated from a standing position.
