Abstract
A system for non-invasively determining the oxygenation state of tissue located beneath the surface of the skin, such as muscle tissue, of an exercising person or other subject is disclosed. In a preferred embodiment, a user-wearable detector array and related circuitry which use near-infrared radiation to collect oxygenation data are provided. The apparatus also includes displays for displaying information regarding the oxygenation state in several ways. In one embodiment a user wearable wristband indicator connected to the detector array which is located at another location, such as on the leg, and provides information directly to the user. In another embodiment, a telemetry device allows remote monitoring of a subject during an activity, the oxygenation information being displayed to a coach or other observer. A separate, user-wearable battery pack, which is preferably designed to provide power for the duration of the activity being monitored, is also provided.
