In spite of advances in neonatal intensive care allowing the first generation survivors of extreme prematurity to now reach young adulthood, these individuals present with reduced exercise capacity; a strong predictor of later chronic disease and mortality. The reason why individuals born preterm have exercise limitation remains unclear and may be a consequence of impact of preterm birth and associated neonatal difficulties on the development of organs important for exercise, namely the lungs, the heart, the vessels (which bring blood and oxygen to the muscles) and the muscles. It is well known that exercise benefits overall health in at-risk as well diseased populations. However, whether exercise training can improve fitness in young adults born preterm was not demonstrated and whether the cardiovascular, pulmonary and muscle impairments associated with preterm birth are reversible through exercise intervention in young adulthood is unknown.
