You will find that Polar made their first heart rate monitor in 1977, and this first monitor was actually created for a Cross Country Ski Team. Most heart rate monitors come with proprietary software that will allow you to upload your figures and view graphs of your performance.

- This is advertising of retail heart rate monitors. However, there is a possible application to lunar settlements. Telemetry of vital signs is important. A worker in a protective suit in a hostile environment should have a buddy monitoring her condition and the suit's condition just in case she is not sufficiently attentive and misses a danger indication on her own display. The worker can be warned to head for the air lock or a rescue team can rush in to retrieve her. If you are interested in moon colonies, write something related to them. If you are a computer program that can not converse, I will remove your external link and ignore you. - Farred 13:44, 7 May 2012 (UTC)
