METABOLISM DURING WALKING. 



person of moderate activity, would be 3.35 calories per hour per 

 kilogram of body-weight. 



INCREMENT IN METABOLISM DUE TO HORIZONTAL WALKING. 



As has been made evident, the values in tables 8 to 12 take no account 

 of the basal standing requirements and only incidentally of the speeds. 

 This has been done in tables 29 to 33, in which are shown the body- 

 weight of the subject with clothing, the distance walked per minute, 

 the horizontal kilogrammeters, i. e., the distance multiplied by the 

 body-weight, the number of steps taken per minute, the elevation of 

 the body in walking (step-lift), the work done due to such elevation, and 

 both the total heat-output and, of main importance here, the incre- 

 ments in the heat-output over the standing requirements.
