Abstract
The present invention provides in various embodiments novel, wearable systems for determining the metabolic condition of an aerobically stressed portion of tissue such as the muscle tissue of an exercising person. Generally, the systems comprise lightweight rugged detectors, worn adjacent the tissue being monitored. The system of the present invention thus minimizes any performance impairment. In preferred systems a wearable power pack and a wearable display means are provided for displaying information indicative of the aerobic metabolic condition of the region being monitored. In a preferred embodiment intended for use while running or engaged in similar athletic activities, the display is worn on the wrist and displays information from a leg-mounted detector. In another embodiment, intended to provide information to coaches, a telemetry system is employed to transmit a signal carrying the data from the detector to a remote location, for processing and display. Various other embodiments and applications are also included.
