- W2492079574 abstract "The best indication of an individual’s ability to perform a physically demanding task is to perform the actual task. However, this is not always safe or practical when selecting an individual for a job. A physical employment test (PET) consisting of basic physical ability tests may be a safer alternative. PURPOSE: The purpose of this study was to use common physical fitness tests (PFTs) to predict Soldier performance of a simulated casualty drag task (CD). METHODS: 608 male and 230 female soldiers were timed (sec) dragging a 123 kg dummy 15 meters as fast as possible, while wearing a fighting load with a weapon (~ 38 kg total load). The CD was performed on a rubber floor and the final score was the speed of dragging in m/sec. Soldiers also performed 14 PFTs wearing shorts, t-shirts and athletic shoes. PFTs included: standing 9 kg overhead medicine ball throw (OT), isometric lifting strength (IL), dumbbell squat lift (SL), seated 2 kg medicine ball put (MBP), 20 m sled drag (SD), standing long jump (LJ), handgrip, 300 m sprint, pushups, sit-ups, isometric biceps curl, beep test, arm ergometer endurance and Illinois agility test. Stepwise multiple linear regression procedures were used to predict CD performance. RESULTS: The model obtained using all possible predictors was: CD (m/sec)= -0.831 + (0.058)(OT m) + (0.002)(IL kg) + (0.005)(SL kg) + (0.060)(MBP m) + (0.136)(SD m/sec) +(0.126)(LJ m), R2=0.72 (p<0.01), SEE=0.23 m/sec. The amount of variability in the prediction accounted for with the addition of each variable was as follows: OT=61%, IL=6.6%, SL=2.5%, MBP=1.4%, SD=0.6%, and LJ=0.6%. Measuring 6 variables to predict one task may not be practical. Examination of the stepwise R2 values revealed that the first two PFTs entered (OT and IL) achieved an acceptable R2 of 0.68. CONCLUSIONS: The use of a whole body power test (OT) and isometric lifting test (IL) provide a reasonable estimate of a person’s ability to perform a heavy CD. In pre-employment screening testing, where it is impractical and unsafe to test an employees’ ability to perform this task, performance can be predicted using simple measures of physical fitness with an acceptable level of accuracy.
