Systematic review and meta‑analysis applying PRISMA guidelines with a PICOS format was constructed to provide an overview of changes in physical performance, body composition and physical training in soldiers during prolonged (≥ 3 months) military operations. Twenty‑four studies out of the screened 4431 records filled the inclusion criteria. A small decrease in endurance performance was the most consistent finding (Hedge’s g [g] − 0.21, 95% CI − 0.01 to − 0.41) while small overall increases in maximal strength of the lower (g 0.33, 95% CI 0.16–0.50) and upper body (g 0.33, 95% CI 0.19–0.46) were observed. In addition, small increases in strength endurance (push‑up, g 0.34, 95% CI 0.15–0.52; sit‑up g 0.26, 95% CI 0.07–0.44) were observed. The overall changes in body composition were trivial. Heterogeneity in the outcome variables varied mainly between low to moderate. Large inter‑individual variations were observed in physical training volume, including decrements especially in endurance training frequency and volume. A reduction in total training load was often associated with negative changes in body composition and physical performance according to the principle of training specificity. Individuals with higher initial fitness level were more susceptible to decrements in their physical performance during operation.
