Spiegler J, et al. - In 1922 preterm-born individuals (aged 5–25), researchers assessed the association of physical activity (PA) and forced expiratory volume in one second (FEV1), peak oxygen consumption (pVO2), body mass index (BMI) and body composition. From the beginning to January 2018, the Cochrane Library, EMBASE, MEDLINE, AMED, ERIC, Web of Science and PsycInfo were searched without restrictions on language and publication date. The results obtained from the systematic review indicate that more PA was related to better cardiorespiratory function in preterm-born children in those groups with impaired lung function or lower BMI in those groups with increased risk factors, but there was no connection in unimpaired children. More PA was linked to higher pVO2 and lower BMI in preterm-born adults. Data reported that only tentative conclusions can be drawn, in particular with regard to the differences in the PA association between preterm- and term-born populations.
