smokers by 3.3 pounds, their lung capacity should, from the standpoint of averages, be correspondingly greater. The following computations are based upon the weight and lung capacity of the non-smoker:
Smoker's lung capacity at 162.9 pounds is 286.3 cubic inches.
Smoker's lung capacity at 162.9 pounds should be 315.3 cubic inches.
In the item of lung capacity, it appears that the effects of smoking are almost completely segregated from those of other factors. The habit of smoking here stands strongly indicted. The evidence becomes little less than proof conclusive when it is noted in the following table that the smokers show a decided loss of lung capacity in each of the six institutions reporting.
|Smokers at||167.4||should have||299.1||14.8|
|Smokers at||166.8||should have||296.8||5.8|
|Smokers at||156||should have||348.9||12.3|
|Smokers at||175.3||should have||343.8||30.8|
|Smokers at||152.5||should have||303.0||38.7|
|Smokers at||158.7||should have||279.8||11.7|
The athletic directors of the various institutions were asked to divide their men into the classes, fair, good, and very good. This classification was to be based upon the ability of the men as all round football players. The following table shows the distribution of the men according to the rating of their coaches:
