METABOLISM DURING WALKING. 



C 



FIG. 35. Typical body-temperature curves of E. D. B., with subject standing, and walking on an 



incline. (Values per minute.) 



1, subject sitting; 2, standing; 3, walking on an incline. Black points, records during experi- 

 mental periods; open circles, records between periods. Curve A, Feb. 29; B, Feb. 22; C, 

 Feb. 17 ;D, Feb. 18, 1916. 



Curve C gives the body-temperature for the experiment of February 

 17, when there was an initial period of standing followed by several 

 periods when the subject walked on a 35 per cent grade at a speed of 

 62 meters per minute. The subject stood after each walking period. 

 In the first 19 minutes of walking the temperature rose 0.82 C., i. e., 

 at the rate of 0.04 C. per minute. The total effect of the exercise was 

 an increase hi the body-temperature of approximately 1.7 C., with a 

 maximum body-temperature of 38.80 C.
