In a DSTO study involving over 100 soldiers, the effectiveness of push-ups, sit-ups and chin-ups was compared to a ‘box lift and place’ assessment method (pictured) that involves lifting a weighted box in a manner that replicates what is required in the field.
The results of this assessment method were then recorded against five strength based task simulations, including ‘bombing up’ a tank, repetitively loading an artillery gun, dragging an injured soldier, building a bridge, and lifting a field pack onto the tray of a truck.
Success with the ‘box lift and place’ assessment method was closely correlated to success in four of the five strength based tasks, while push-ups and chin-ups correlated with only one of the five job tasks (bridge building).
“The box lift assessment is a far superior predictor of job performance,” Mr Carstairs said.
