Abstract: A method includes collecting a set of user information, determining a user current performance by: determining a sleep score or debt, measuring the user's previous physical activity, heart rate, or body temperature, calculating weights for the sleep score and the sleep debt, the measured previous physical activity, heart rate, or body temperature, calculating a weighted sum of the weighted sleep score, the weighted sleep debt, the weighted user's previous physical activity, weighted heart rate, or weighted body temperature, setting a user target level of performance, measuring a circadian rhythm and a user's duration of sleep or sleep cycle, comparing the circadian rhythm, the duration of sleep or sleep cycle, the current performance level, and current time zone information over days to determine a separate user performance level, comparing the target level of performance to the separate user performance level, and providing an alert and feedback user related to the comparison.

Abstract: A method and a system for assessing readiness of a user, the method including obtaining the user's movements; using the obtained user's movements to determine a nature of the period, wherein the nature of the period is selected from an activity period and a rest period; measuring at least one biosignal of the user during the rest period; determining a rest summary for the rest period, based on the measured at least one biosignal and at least one biosignal of a previous rest period; determining an activity summary for the activity period, based on the obtained movements of an activity period and obtained movements of at least one previous activity period; determining a body response summary based on the rest summary and the activity summary; and calculating a readiness score based on the body response summary and a previous body response summary, whereby the readiness score indicates a level of readiness of the user.

Abstract: Disclosed is a system for providing feedback to a user for improving performance level management. The system includes a wearable electronic device with means for measuring circadian rhythm and duration of sleep; a mobile communication device configured to communicate with the wearable electronic device; and a server configured to communicate with the mobile communication device, and operable to collect a first set of information from the user, calibrate the first set of information based on a set of measurement data from the wearable electronic device, set a target level of performance of the user, compare the measured circadian rhythm, the measured duration of sleep and time information against each other and a set of rules to determine the performance level of the user, compare the determined performance level to the target level of performance, and provide an alert and feedback when the determined performance level is below the target level of performance.
