Abstract:

     In order to measure non-invasively the effectiveness of
ground-based and space exercise regimens, this project will
investigate the lactic acid content in human sweat as an effective
measure of maximal aerobic power. The firm has a sweat "Patch"
specimen container which can continuously and non-invasively
monitor individual lactate levels for one week. Phase I will
explore the effectiveness of lactate monitoring in sweat as a
predictor of the lactate profile in blood. Phase II will extend
the levels of exercise performed and the categories of individuals
monitored. Phase II could also include space studies during
extended (i.e., greater than 15-day) missions. 

Potential Commercial Application:

Potential Commercial Applications:  The most obvious commercial
application would be the general health and fitness market where
individuals could monitor themselves and establish performance
profiles. In addition, remote care facilities could use the device
to monitor long-term patient metabolic rates.
