- Original description
Continuous glucose monitors, as a technology that aims to improve glycaemic control in patients with type 1 diabetes, must always adjust to changes in blood glucose levels in these patients, e.g. during sporting activities. In women, in particular, menstruation and its different phases can affect blood glucose levels in different ways. Therefore, this study aims to determine whether there is a different behaviour of blood glucose levels during aerobic or high-intensity exercise in different phases of menstruation. If so, we will try to model this behaviour and create specific guidelines in this regard in terms of physical exercise programming in women. In addition, the information derived from this study will be used to design better artificial pancreas systems that take into account the effects of the menstrual cycle in women.Read full original descriptionShow less
