Low baseline fitness of recruits entering basic military training (BMT) is associated with an increased risk of musculoskeletal injuries (MSIs) and attrition from training.
To determine the effects of a pre-training conditioning program (PCP) on aerobic endurance, incidence of musculoskeletal injuries (MSIs), and attrition rates in BMT of a special infantry unit of the Netherlands Armed Forces.
Recruits were considered eligible for this study when they were 'low-fit' at the start of BMT (time to complete a 2.7-km run ≥ 12'23″).
'Low-fit' recruits were deferred to a seven to twelve week-depending on the time between two consecutive training platoons-PCP consisting of functional training to improve several fitness domains. The control (CON) group started regular BMT without delay.
Forty-nine recruits were included in this study; 26 in the PCP-group and 23 in the CON-group. Recruits who followed the PCP started BMT with better aerobic endurance than the CON-group who started BMT immediately (2.7 km run timings: PCP 11'32″, CON 13'16″). The risk of dropout was lower in the PCP-group (incidence density ratio (IDR) 0.63, 95%CI 0.32; 1.26), but dropout due to training-related MSIs was more frequent (IDR 1.23, 95%CI 0.32; 4.76 (per-protocol 0.94, 95%CI 0.24; 3.63), without statistically significant differences between the groups.
Although a PCP was effective to improve aerobic endurance in low-fit recruits to return to meet pre-enlistment fitness criteria, we could not demonstrate an effect on dropout from military training.

进入基础军事训练（BMT）的新兵基线体能较低与肌肉骨骼损伤（MSIs）风险增加及训练淘汰率升高有关。
确定训练前体能训练计划（PCP）对荷兰武装部队一支特殊步兵部队BMT中的有氧耐力、肌肉骨骼损伤（MSIs）发生率和淘汰率的影响。
新兵在BMT开始时“体能不佳”（完成2.7公里跑步时间≥12分23秒）时被认为符合本研究条件。
“体能不佳”的新兵根据两个连续训练排之间的时间间隔推迟参加为期七至十二周的PCP，该计划包括功能性训练以改善多个体能领域。对照组（CON）立即开始常规BMT。
本研究纳入49名新兵；PCP组26名，CON组23名。参加PCP的新兵开始BMT时的有氧耐力优于立即开始BMT的CON组（2.7公里跑步时间：PCP组11分32秒，CON组13分16秒）。PCP组的退出风险较低（发病密度比（IDR）0.63，95%CI 0.32；1.26），但因与训练相关的MSIs导致的退出更频繁（IDR 1.23，95%CI 0.32；4.76（符合方案分析为0.94，95%CI 0.24；3.63），两组间无统计学显著差异。
尽管PCP有效地提高了体能不佳新兵的有氧耐力，使其恢复到入伍前体能标准，但我们未能证明其对军事训练淘汰率有影响。
