The standard knee pad is considered the most ineffective personal protective equipment in the American football player’s uniform. This study quantitatively and qualitatively assesses personal protective equipment for the lower body for U.S. football players against the VAPPR Pad (Vastus And Patellar Protection with Range of motion), the next iteration of lower body protection. The study consisted of player surveys, material drop testing, and Performance Drill testing including broad-jump, L-drill, pro-agility, and gait analysis with 138 participants in the initial survey and 25 men in the physical testing. Results of the Performance Drill Testing proved that unpadded players perform at higher levels than padded players; established no difference in performance between the unpadded players and players wearing the VAPPR Pad; and validated the VAPPR Pad’s superiority to the standard knee pad.
