Abstract:
1. A system for monitoring physical activity, the system comprising: a plurality of heart rate monitors that can be assigned to individuals, each heart rate monitor comprising a detector for creating heart rate data that provides a measure of the individual's heart rate, a memory for storing the heart rate data, and a transmitter for transmitting the heart rate data; at least one receiver station comprising a receiver for receiving heart rate data transmitted from the plurality of heart rate monitors; a data management server connected by a communications network to the receiver station, to receive the heart rate data from the receiver station over the network; and a database associated with the data management server for storing the heart rate data received by the data management server; wherein each heart rate monitor is configured to automatically transfer the heart rate data to the receiver station when the heart rate monitor is in range of the at least one receiver station and to store heart rate data in the memory when the heart rate monitor is not in range of the at least one receiver station, the at least one receiver station being configured to transmit a polling signal for detection by the heart rate monitor or the heart rate monitor being configured to transmit a polling signal for detection by the receiver in order to determine when the heart rate monitor is in range of the receiver station.
