464 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 

 PULSE-RATE BEFORE AND AFTER WORK ON BICYCLE ERGOMETER, SQUAD B. 



Although Professor Johnson rightly laid special emphasis upon the 

 values obtained with Squad A, those for Squad B also have a special 

 significance, owing to the fact that they present a large number of 

 normal values for comparison with those obtained during the short 

 period of reduced diet. The values for Squad B are recorded in de- 

 tail in table 107, in which is given for each subject the pulse before 

 the experiment, the pulse one minute after riding, the percentage 

 increase, and the number of minutes required for the pulse to return to 

 normal. With two subjects, Kim and Sch, the early basal values are 

 missing, although we have one or two post-diet values with each of. 

 these subjects. The pulse-rate prior to riding has been discussed in 

 connection with table 85 (see page 400) and with Squad B shows the 

 usual fall during the period of restricted diet. Since no pulse values 

 previous to the reduction in diet were obtained with Squad A, a special 

 significance of the results in table 107 must be the relative constancy of 

 the basal values, i. e., the normal values obtained outside the low-diet 

 period. When the change was made to a restricted diet, there was a 

 characteristic decrease in pulse-rate, the significance of which has been 

 previously discussed. Squad B shows on the resumption of unre- 



^More than 20 minutes required for pulse-rate to return to normal.
