On the subject of submaximal tests, Astrand suggested certain Although nobody uses the human calorimeter these days on account of the difficulties of technique, Atwaters experiment was the first of its kind which demonstrated that the human body behaved like any engine running on combustion of fuels, thus taking the wind out of the sails of the theory of living matter possessing vital spirits. 2. in the one case and 2 I/min in the other.
