The principal hypothesis of this study is that the micro and macro vasculature of young
diabetes mellitus type 1 (DM1) patients is particularly susceptible to atherogenic factors
which cause vascular dysfunction at multiple levels of the arterial vasculature and that
this dysfunction is demonstrable using state-of-the-art ultrasound methods. The
investigators further hypothesize that interventions, such as exercise, that are readily
integrated into the daily life of individuals with DM1 can mitigate or reverse these early
vascular changes and thereby diminish the otherwise predictable longer-term development of
cardiovascular disease (CVD) in type 1 DM
