The review aimed to describe the effects of military training that combine intense physical activity and sleep deprivation on oxidative stress and cellular injury markers, as well as physical and cognitive performance. A systematic review was conducted following PRISMA recommendations, and the search was conducted in Pubmed and Google Scholar databases. The string was developed to identify experimental studies that investigated pre- and post-military training moments, evaluating at least one of the dependent variables: oxidative damage, antioxidant capacity, cellular injury, cognitive alertness, and physical performance. Twenty-four studies met the inclusion criteria. The interventions of the included studies ranged from 1 to 63 days, with a predominance of intense physical activity and significant sleep deprivation. Comparisons of paired data converged with increased levels of cellular injury and decreased physical and cognitive performance (p<0.05). There was a paucity of oxidative stress assessments and the distinction between the protocols of the studies found. The review concluded that the combination of intense physical activity and sleep deprivation is capable of causing increased levels of cellular injury and decreased physical and cognitive performance. It also suggests that there is an information gap between oxidative stress and military training.
