Exercise in Prematurely Born Preadolescents to Mitigate Cardiovascular Risk and Improve Cognitive Impairment

EXCELSIOR is a randomized controlled trial to investigate the effect of physical exercise on cardiovascular health in prematurely born children. Participants will be randomly allocated to either an intervention group or a control group. The intervention will receive a child-friendly physical exercise program and the control group will receive age appropriate lifestyle- and exercise recommendations.

Premature birth, i.e. the birth of babies before the 37th week of pregnancy, is an increasing challenge. Since the 1980s, medical advances such as special medication and ventilation techniques have significantly improved the chances of survival for premature babies. Worldwide, around 11% of all births are premature. Prematurity increases the risk of cardiovascular disease. Studies show that very premature babies have a significantly higher risk of heart problems. However, only little is known whether physical exercise could improve cardiovascular and cognitive function in prematurely born children. All participants will undergo a baseline visit to assess vascular, cognitive and cardiopulmonary function. At the end of the visit, participants will be randomly allocated to either an intervention group or a control group. The intervention will receive a child-friendly physical exercise program and the control group will receive age appropriate lifestyle- and exercise recommendations. The physical exercise program is held 2-3 times per week for ten weeks targeting cardiovascular health and coordination. After 10 weeks, all participants will undergo a follow-up visit at which all measures will be repeated.
