I developed rat exercisser/treadmill with humane stimulus (small
container with cold water ) placed at the end of exercisse lane.
Water container is chilled by thermoelectric cooler to aprox.
freezing point. As rat uses his tail for thermoregulation of
body, cold water serves as a good and humane enticement to keep
him exercissing. Exercisse belt in placed in the enclosed chamber
and therefore simultanous measuremnts of VO2 max. and VO2/VCO2
are possible using gas analyzers. Smaller model for mice was also
developed. Exercisser can be combined into multi line systems
operated by the same electric motor. Speed and belt elevation are
adjustable in wide range.
If you are interested in this exercisser please e-mail your
street address and I will send you more information.
