ENERGY TRANSFORMATIONS DURING HORIZONTAL WALKING. 



TABLE 1. Historical summary of walking 



*The summarized data in this table are based on published material cited on pp. 11 to 21. 



2 Calculated from the data available, assuming a respiratory quotient of 0.85 and 1,609.35 

 meters per mile. 



'Computed with several necessary assumptions, i. e., length of step, 0.680 meter; number of 

 steps, 80 per minute for second figure as well as for the first; respiratory quotient, 0.85. 



4 Values computed by Durig (Denkschrift. d. math.-natur. Kl. Akad. Wissensch., 1909, 86, 

 p. 242), including correction for angle of ascent as indicated by Katzenstein. 



6 A11 heat values computed by Durig (loc. cit., p. 256), assuming respiratory quotient of 0.85. 

 Corresponding figures assuming a quotient of 0.75 were: 0.559, 0.373, 0.515, and 0.358.
