A system for monitoring muscle load, is configured to perform operations including: obtaining, from at least one sensor, measurement data on an exerciser; determining, based on the measurement data, a number of repetitions of a macroscopic movement performed during a physical exercise; determining, based on a conversion entry corresponding to a type of the physical exercise, muscle load coefficient of one or more muscles loaded in the physical exercise; utilizing the muscle load coefficient of the one or more muscles and the number of repetitions in determining muscle load data indicating muscle specific muscle load caused by the physical exercise performed by the exerciser; and outputting the muscle load data.

Muscle load monitoring

There is provided an apparatus, wherein the apparatus is configured to perform operations comprising: obtaining heading information indicating a target heading to a target; detecting, during swimming, that the swimmer deviates from the target heading; and informing the swimmer, via a user interface element, that the swimmer has deviated from the target heading.
