The present study investigated performance changes during three runs (1 min recovery) of repeated military simulation task test (RMST) and its associations with physical performance. Voluntary male soldiers ( = 114) participated in a series of measurements of physical performance. Lower body explosive force production, anaerobic endurance and upper body strength endurance together explained 58% of the variance in the first RSMT ( < 0.001). The same variables explained the variance in the second and third runs of RSMT by 60% and 51%, but explosive force production was replaced with aerobic endurance, assessed by the 3.2 km loaded run ( < 0.001). This study demonstrated that the role of explosive power of the lower body decreased and military specific aerobic endurance increased when occupational performance was assessed under acute fatigue even during a short high-intensity test. These results may benefit tactical strength and conditioning coaches in training optimisation for improved occupational performance in military. Soldiers are required to perform occupational tasks in a repeated manner with short recovery time. In the present study, the role of explosive power of the lower body decreased and military specific aerobic endurance increased when occupational performance was assessed with a repeated high-intensity task specific performance test.
本研究调查了三次重复军事模拟任务测试（RMST）期间的表现变化及其与身体表现的关联。自愿男性士兵（n=114）参加了一系列身体表现测量。下肢爆发力、无氧耐力和上肢力量耐力共同解释了第一次 RMST 中 58%的变异（<0.001）。同样的变量解释了第二次和第三次 RMST 运行的变异，分别为 60%和 51%，但爆发力被通过 3.2 公里负重跑评估的有氧耐力所取代（<0.001）。本研究表明，即使在短时间的高强度测试中，当评估职业表现时，下肢爆发力的作用降低，而特定于军事的有氧耐力增加。士兵需要以重复的方式执行职业任务，并有短暂的恢复时间。在本研究中，当使用重复的高强度特定任务表现测试评估职业表现时，下肢爆发力的作用降低，而特定于军事的有氧耐力增加。
