System for player workload monitoring. The player wears a small tag. Data acquired are transmitted to the analyst via a smartphone, resulting in physical metrics, i.e., on the external load of the training or competition session. Key metrics are to be used to monitor in particular the acute:chronic workload ratio on a week by week basis. The tag is also able to acquire heart rate data as a measure of internal load.
