400 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



period of muscular repose. Under these conditions, as may be seen 

 from table 80, striking irregularities are usually avoided and the pulse- 

 rate seems to provide an admirable index of the general metabolic 

 condition. 



PULSE-RATE, LYING BEFORE WORK, SQUAD B. 



The absence of pulse observations on Squad A prior to the period 

 of diet restriction is a fault in the pulse study with this squad. With 

 Squad B, excepting when they were on low diet January 8 to 28, 

 inclusive, certain values were obtained which make up in part for this 

 deficiency in normal values with Squad A. Thus, beginning October 

 24, Professor Johnson obtained lying values for the pulse-rate of these 

 subjects prior to work, and as the squad had no diet restriction until 

 January 8, the values between these two dates supply material for 

 comparison. The pulse values recorded by Professor Johnson are 

 given in table 85 for both the normal, restricted, and unrestricted diet 

 periods. The daily averages are given for these subjects as was 

 done for Squad A.

just prior to work on the bicycle ergometer, constancy having been obtained for several 



counts. 

 ' On March 1 the pulse-rate of Lon was 61 ; of Kim, 69. 



The pulse-rates of the several men did not vary widely from day to 

 day prior to the period of diet restriction, except in one or two instances, 

 such as with Har, whose records varied from 53 to 74. Usually the 

 ranges are within 8 or 14 beats. The average daily rate was 66 for
