Abstract
A metabolic fitness training apparatus is provided which measures the concentration of acetone in a trainer's breath while exercising. The metabolic fitness training apparatus include a housing, an acetone sensitive sensor, an optical detection circuit, and a mouthpiece attached to the housing. The sensor contains reagents such as salicylaldehyde or derivatives thereof which react with acetone to change the optical transparency of the sensor. The optical detection circuit may include a LED and a photodetector or a photometric instrument to measure the change in optical transparency of the sensor, and convert that change to acetone concentration. There may also be a display for viewing the acetone concentration.
