414 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



normal diet with Squad B. The increments on reduced diet with Squad 

 B (see January 28) range from 31 with Sne, who Hkewise showed the 

 highest increment on normal diet, to 9 with Wil. Excluding Sne, we 

 find the average increment on reduced diet to be somewhat less than 

 20, which is in full conformity with that noted for Squad A. 



Although the abnormally high increases for Can on February 3 and 

 for Sne on January 6 and January 28 were eliminated from the aver- 

 ages, and the average increment for the standing position remains 

 essentially the same on all three days, namely, 17, 18, and 19 beats, 

 it can be seen that including these men in the average would but 

 slightly alter the differences between these increases, and the increment 

 due to change in position from lying to standing was practically the 

 same under normal conditions and with reduced diet conditions. The 

 normal values in this case are, however, represented by only one day 

 (January 6) and the reduced diet by two days (January 28 and 

 February 3) with different squads. Special attention should be called 

 to the low averages for the basal pulse on the reduced diet days, these 

 being 45 for Squad A and 40 for Squad B. 



These increases are expressed in actual pulse beats, but it should be 

 noted that the percentage increase is very considerably greater during 

 the restricted diet than with the normal diet. Thus with Squad A 

 the increase of 17 beats on February 3 with the basal value of 45 rep- 

 resents a percentage increase of 37.8 per cent. With Squad B on 

 reduced diet (January 28), the increase of 19 on a basal value of 40 

 represents 47.5 per cent, while with Squad B on normal diet (January 

 6) the increase of 18 on a basal value of 56 represents 32.1 per cent 

 increase, a materially lower figure. 



In general, it can be seen that a change in position from lying in 

 the group respiration chamber to standing with the portable respira- 

 tion apparatus leads to an increase in pulse-rate of not far from 18 

 beats, an increment which is slightly greater in absolute terms and 

 considerably greater in percentages with reduced diet than with 

 normal diet. These differences, however, are not to be confused with 

 the absolute height of the pulse-rate, which is much lower on the re- 

 duced days than on the normal days, this being shown more clearly 

 with Squad B than with Squad A. 



STANDING PULSE RECORDS PREVIOUS TO TREADMILL EXPERIMENTS. 



A still further record of pulse-rate for the standing position was 

 obtained just prior to the walking experiments, when the subject was 

 standing outside the chamber or on the treadmill prior to the actual 

 walking test. Although these pulse-rates, which were recorded by the 

 string galvanometer method, have a greater significance in indicating 

 the transition pulse from standing to walking and the reverse and 

 will be considered later in connection with the pulse-rate obtained 

 during walking, they are also perfectly comparable with the other
