A method and an apparatus for performing the method are disclosed. The method includes obtaining cardiac output power data on a user; obtaining kinetic data characterizing physical exercise intensity of the physical exercise performed by the user; detecting that a measured cardiac output power exceeds a first threshold or that physical exercise intensity changes according to a rate exceeding a second threshold; upon the detecting, determining a synthetic cardiac output power parameter based at least partly on the kinetic data; and outputting the synthetic cardiac output power parameter.

Synthetic cardiac output power parameter

A wristband, an electronics module, and a wrist device are disclosed. The wristband and the electronics module form the modular wrist device. The electronics module, when mounted to the wristband, stiffens a structure of at least a portion of the wrist device in order to enable the wrist device to firmly attach against a wrist of a user and to enable optical heart activity measurement by the electronics module.

Performance intensity zones are disclosed. An apparatus comprises one or more processors, and one or more memories storing instructions, that, when executed by the one or more processors, cause the apparatus to: obtain performance intensity data measured from a user with at least one measurement sensor during a first activity and/or a second activity; and classify the performance intensity data in relation to a plurality of predetermined performance intensity zones, wherein each performance intensity zone is predetermined by a first numerical range for the first activity, and a second numerical range for the second activity, wherein the first activity and the second activity are different types of sports or different types of physical activities.
