The wearable strap may monitor heart rate data including heart rate variability, resting heart rate, and sleep quality. The systems may include a processing module that generates an indicator of physical recovery based on the heart rate data. The recovery indicator may be used to determine strain related to an exercise routine, qualitative information on the user's health, whether to alter a user's exercise plan, and so forth.

Using an Online Disturbance Rejection and Anticipation System to Reduce Hyperglycemia

Embodiments relate to systems and methods for informing, determining, or controlling insulin dosage. The method involves generating plural disturbance profiles, each disturbance profile being a data representation based on historical patient data pertaining to a deviation from a threshold blood glucose level. The method involves receiving current patient data. The method involves applying a predictive model so that current patient data is compared to a disturbance profile and a probability analysis is used to assess the likelihood of a disturbance profile being an anticipated disturbance profile, the anticipated disturbance profile being a disturbance profile that is determined to match with the current patient data based on the probability analysis. The method involves determining an insulin dose amount based on the anticipated disturbance profile. The method involves outputting a signal representative of the insulin dose amount to a device configured for monitoring, influencing, and/or administering insulin levels in the patient.
