International Journal of Exercise Science

International Journal of Exercise Science 12(4): 847-858, 2019. The body drag (BD) is used as a test to measure a law enforcement officer (LEO) recruit’s capability to rescue an individual. However, the physical characteristics associated with faster BD performance have not been identified. It could be expected that lower- body power, often measured via jump performance, could positively relate to BD performance. This study investigated the relationship between the vertical jump (VJ), peak anaerobic power measured in watts (PAPw), power-to-body mass ratio (P:BM), standing broad jump (SBJ), and relative SBJ, with BD velocity in LEO recruits. Retrospective ...
