The AR and NR treatment groups lost protein from the oral frame at the same rate throughout the ex- periment (P = ). The AR treatment lost protein from the distal arms at a higher rate than did the AC treatment group (P < ). Carbohydrate content changes. The results of the total body carbohydrate assays are graphed by day in Figure 5B. The NC and NR groups did not exhibit any significant change in total carbohydrate concentration with time (P = , P = ). The AC and AR groups did exhibit changes in total carbohydrate concentration (P = , P < ) over the course of the experiment. There was no difference in the rate of loss between the AC and AR groups (P = ). The changes in carbohydrate concentration of the var- ious body parts with time in the different
