“…Some other studies have used lift heights comparable with the 1.45-1.70 m of primary interest to the British Army, but have limited the mass lifted to 72 kg which affected the performance score of a significant proportion of subjects (17,18) or have been focussed on repetitive lifting capacity (2,7). The studies providing data most relevant to maximal box-lifting ability to 1.45-1.70 m have suggested that simple anthropometric measurements including stature, fat-free mass and chest circumference (12, 13, 15, 17, 18), isometric back extension or lifting strength (12,15,17,18,20,21) and dynamic strength assessed using an incremental lift machine (13, 15,17,18,20,21) are probably the most useful predictors of task performance. However, it would also be useful to determine the ability of a safe, easily controlled free weight exercise (requiring only widely available apparatus) to predict box-lifting ability.…”
