International Journal of Exercise Science

International Journal of Exercise Science 11(4): 1063-1073, 2018. The purpose of this study was to investigate the relationships between tests incorporated into a physical assessment battery (PAT) for a law enforcement (LEA) to determine if there were redundancies (i.e. tests measuring the same qualities). A retrospective analysis of 226 recruits (196 males, 30 females) was conducted. The PAT consisted of: maximal push-ups and sit-ups completed in 60 s; a 75-yard pursuit run (75PR); maximal revolutions completed on an arm ergometer in 60 s; and a 2.4 km run. A one-way ANOVA (p<0.05) determined if there were significant differences in the PAT data between the sexes. Pearson’s correlations (p<0.05) calculated relationships between each of the tests within the PAT, and males and females were analyzed separately. Further, tests that could potentially measure similar qualities, including upper-body endurance (push-ups/arm ergometer), abdominal endurance (push-ups/sit-ups), and aerobic fitness (arm ergometer/2.4 km run) were investigated further with one-sample t-tests to determine agreement. Males performed better than the females in all tests (p≤0.017). There ...
