METABOLISM DURING WALKING. 



TABLE 33. Increase in heat-output of J. H. G., E. L. F. and H. M. S. during horizontal walking~_in 

 experiments without food. (Values per minute.) Continued. 



In considering the data in tables 29 to 33 for the increment over the 

 standing requirement, it should be remembered that, as explained on 

 page 94, the standing metabolism was not obtained on each day that 

 walking experiments were performed and whenever this was the case, 

 an average value, or a value determined from a series of days nearest 

 the time of the walking experiments, has been used. The selection of 

 the standing values to be used on those days for which it was not de- 

 termined has been a matter of some difficulty. Thus, H. R. R. on 

 March 20 showed an unusually high standing metabolism. This 

 value has been employed in computing the increase for walking on that 

 day, but it has been considered that probably the measurements found 

 on April 10 and 17 more nearly represent the normal basal metabolism 

 for this man, and the average for these two days has been used in
