PURPOSE: To investigate the utility of existing recruit physical barrier tests in predicting performance of occupationally-relevant tasks. METHODS: All recruits participating in the study were undertaking the Australian Army 12-week basic training course. A total of 186 male recruits were included in the study (age 21.6 ± 4.2 y, height 178.6 ± 6.8 cm, mass 77.7 ± 11.9 kg). Physical performance was assessed at weeks 1 and 11. At each time point participants were subjected to a battery of tests that comprised: generic fitness tests; maximal push-ups (2 min) and multi-stage shuttle test (MSST) and military-related tests; 1repetition-maximum box lift and place and 3.2-km loaded run (22 kg). The ‘generic fitness tests’ form part of the Australian Army recruit physical barrier tests. All data is reported as mean ± SD and significance was set at p < 0.05. RESULTS: Maximal push-up performance during week 1 of basic military training (BMT) was not correlated with box lift and place performance at week 1 or 11 (r2 = 0.097 and 0.113 respectively, p>0.05). Push-up performance was moderately to strongly correlated with load carriage performance at week 1 and 11 of BMT (r2 = -0.514 and -0.406 respectively, p<0.05). Maximal MSST performance during week 1 of BMT was strongly correlated with load carriage performance at both week 1 and 11 of BMT (r2 = -0.676 and -0.520 respectively, p<0.05). CONCLUSIONS: The results showed that performance in the MSST and push-ups were moderately to strongly correlated with load carriage performance. The predictive utility of these generic fitness tests decreased over BMT. There was a weak correlation between push-up performance and occupationally-relevant muscular strength performance. Both manual handling and load carriage are enduring requirements for Army personnel. In fact, a recent review of physically demanding tasks across all Army employment categories revealed that muscular strength was the dominant physical capacity. These results indicate that the current Australian Army recruit physical barrier tests do not predict the ability of male candidates to perform key occupational tasks (i.e. manual handling). It is therefore recommended that an additional test is incorporated into the recruit barrier test battery that assesses and/or predicts whole-body muscular strength performance.
