First publication of the Australian Journal of Sports Medicine, which was later renamed the Journal of Science and Medicine in Sport.
Exercise test with a hand-cranked, electrically braked ergometer. The spirometer was a closed circuit Knipping Model 210 D, manufactured by the company of German instrument builder Albert Dargatz (1857-1941).
American Professor Karlman Wasserman (1927-2020) of the UCLA Harbor Hospital Medical Center in Torrance, California, was one of the first to use exercise tests to study the interaction of cardiovascular, metabolic and respiratory reactions in humans. He is best known for his description of the 'anaerobic threshold' by using respiratory and cardiovascular gas exchange reactions during exercise tests.
He pointed out that the buffer rate of the accumulating lactic acid must be observable in the exhaled gas and must be quantifiable by breath. The original description was published in the American Journal of Cardiology in the fall of 1964. The Wasserman 9-Panel Plot, often also called Nine-Panel Plot, is a standard format for the graphical representation of data produced during a cardiopulmonary exercise test. The layout was updated in 2012. The graphs provide an overview of cardiovascular, respiratory and gas exchange parameters
