ABSTRACT

ABSTRACT Moreno, MR, Dawes, JJ, Orr, RM, Dulla, JM, and Lockie, RG. Relationships between strength and power with the 74.84-kg (165-lb) and 90.72-kg (200-lb) body drags. J Strength Cond Res 38(7) 1305-1313, 2024-A body drag is an essential job task in law enforcement. It is purported that strength and power should contribute to this task, but there has been limited analysis. This study examined strength (1-repetition maximum hexagonal bar deadlift [1RM HBD]) and power (vertical jump [VJ], standing broad jump [SBJ]) relationships with the 74.84-kg and 90.72-kg body drags. Forty-three civilians (24 men and 19 women) completed the SBJ, VJ, and 1RM HBD in 1 session. Peak anaerobic power measured in watts (PAPw) was derived from the VJ. Relative measures were calculated from the SBJ, PAPw, and HBD. In another 2 sessions, subjects completed 74.84-kg and 90.72-kg drags in a counterbalanced order using 2 techniques standard and adapted (time taken to pick dummy up from ground included in time). Independent samples t-tests compared the sexes and subjects who could or could not complete all drags. Partial correlations and stepwise regression, both controlling for sex, examined relationships between strength and power and the drags. In general, men outperformed women in almost all tests (p ≤ 0.024). Thirty-five subjects completed all drags and were stronger and more powerful than subjects who could not (p ≤ 0.011). The SBJ correlated with the 74.84-kg standard (r = -0.355) and 90.72-kg adapted (r = -0.373) drags; the VJ correlated with the 74.84-kg standard drag (r = -0.356). Peak anaerobic power measured in watts and 1RM HBD correlated with all drags (r = -0.382 to -0.668); PAPw was involved in all significant predictive relationships (explained variance = 34-62%). Absolute strength and power training should be a focus for recruits to enhance their ability to perform dragging tasks, especially with heavier masses.
