October 27: Not tired from the 5-mile run this morning. November 10: Legs somewhat weak in the cross-country race this morning. At times, does not feel able to do cross-country work. Muscles of legs have pained him some lately. November 24: Finds that he is weak on the indoor gymnasium work. Until now he has only been doing running this year; recently on one evening he boxed 20 minutes, wrestled for 20 minutes, ran a 2-mile race in 10 minutes, and felt very good afterwards. "With me the more exercise the better, but I feel the weakness in the legs reported by the other men." December 8: Still has weakness in the legs. December 12: "This morning is the first time in two months that I have been able to run up all the flights of steps to the fourth floor two steps at a time. I feel fine." December 19: Physically never felt better than during last 10 days; not bothered about going upstairs now. In gymnasium apparatus work, however, he has no strength in his arms. No desire for diving and swimming, as he usually has. January 26: During last fortnight has not felt nearly as well as before Christmas. Tired and weak most of time, having the same amount of exercise as before Christmas. He cannot perspire with any kind of exercise now. February 2: "In the cross-country running in the fall I noticed hardly any change, except in lack of ability to sprint at the end of the race.
With gymnasium work in general I noticed particularly weakness in the wrists, ankles, and in the other joints under conditions of suspension." May 22: Recalled his feelings of weakness in the knees, ankles, and wrists associated with the experiment. Spoke of the pleasure he experienced at being able to run up all the stairs to the respiration laboratory in the dormitory before the Christmas vacation without the subjective sensation of weakness. "One can run upstairs on his nerve even though he has the weakness, but there were times, I believe, when I could not possibly run up more than one flight of steps." The subject differentiated sharply between those periods in the experiment when the weight was actively reduced, as in October, November, and January, and the long period of weight maintenance in December. "During the period of reduction, one is physically uncomfortable, ineffective, and hungry all the time." In his own case he frequently had to go to bed early in the evening to forget his unpleasant feelings. "Concerning the cross-country races, I was beaten in the two intercollegiate events, once by a Wesleyan man whom I beat last year. In both races the representative from the other team and myself led the race. We ran well together until we came near the end. As we left the swamp about a quarter of a mile from the finish and started up the long grade, the other fellow simply went away from me in spite of all that I could do. I seemed to have plenty of endurance, but I could not sprint as normally for the finish. Following the race I was in much better physical condition than the other runners. They were exhausted and nearly at the point of physical collapse, while I felt fine and could have run again. In reference to the gymnasium work, as I have stated, I always noticed the lack of strength in my wrists and arms to do the apparatus work".
November 10: Notices a loss of "pep" and staying power (endurance); all right after he once gets started; notices weakness in climbing stairs. Had to work hard to reduce and thought this made him weak. January 12: "Feel stronger and more comfortable than before Christmas. I am playing hockey as goal tender now." January 26: " During last few days I ran down in vitality but not in weight." February 2: "I have felt rather better than usual physically during the week; continually improving since early days of experiment." February 8: Hockey game was lost by a heavy score. Thought to have been due to the subject's weakened physical condition.
November 10: Feels weak tonight, particularly in going upstairs. When he rises suddenly, everything turns black. After work in the afternoon, if he walks up three flights of stairs to respiration laboratory he is more tired than usual. He has as much " pep" as before diet. November 24: Has not the endurance for physical work that he formerly had. A swim of two full lengths of the pool makes him tired; not so usually. Weakness in the legs is conspicuous. May 22: "I think it is quite logical for a man to say that he is weak in the knees, and later be seen to run up and down stairs. I remember clearly that I used the stair rail more when going up and down stairs and bore part of my weight with the hands. In the fall term I did practically as well as usual in class football team practice against the university team as I would have done under normal conditions. I think, however, that in the winter term my athletic work was not up to standard".
November 10: "Was up late last night and had only 4 hours' sleep. Tearing around Boston this afternoon and am sleepy now, but otherwise I feel good." November 24: "I feel fine, but cannot get thinner. I have not the time to work off flesh the way the other fellows do." December 19: "Feelings of weakness are not prominent in my case." January 26: "I am not recovering from my operation as I should and my physical condition is poor." February 8: Has more "pep" and strength than at the close of the diet period.
October 27: "Played tennis all the morning. I am feeling all right." November 10: Feels about the sarnie, except legs get a little more tired than usual. Has been doing more work than usual in order to reduce. "If I could eat food that would go to my legs I would feel all right. My legs are weak. I notice it particularly when walking upstairs. It can not be because of an over-amount of exercise." November 24: Past week much tiredness in legs. January 12: Noticed a little tiredness in the legs. January 26: "This week I have been tired all the time. I do not know why." May 21: "The sensation of weakness in the legs was not so prominent when I was running. It is all gone now".
