A method of determining when a subject is experiencing anaerobic exercise during an exercise session, for determining effectiveness of a training period, and/or for determining a level of lactic acid produced by a subject during an exercise session may involve the administration of a bicarbonate comprising a carbon-13 isotope. Expired air may be monitored, and a ratio of carbon dioxide comprised of the carbon-13 isotope and carbon dioxide comprised of a carbon-12 isotope may be determined at one or more points in time. Charts of the ratios may be used to indicate onset of anaerobic exercise or effectiveness of a training period, and/or the determined ratio(s) may be used to indicate lactic acid production.

Noninvasive method for measuring lactic acid and detection of anaerobic exercise for evaluating fitness

There is disclosed a method for preventing or minimizing biodegradation of a substance which normally contains a naturally occurring optical isomer which comprises replacing the naturally occurring optical isomer with the corresponding unnatural optical isomer.
