Resting metabolic rate vs. gastrocnemius surface concentration. The figure represents the metabolic rate equations plotted vs. the surface concentration equations over the weight range for which metabolic rate determinations were made. Symbols are as in Figure 3. a species constant. R. clamitans is assumed to belong to the same plot with R. pipiens. All sections examined indicated a bimodal frequency distribution of fiber cross-sectional areas, with about equal numbers of large and small fibers. Since muscle surface concentration varies directly as W-^>, it would seem that growth of the muscle is accomplished strictly by enlargement of fibers present at the completion of metamorphosis. Preliminary inspection indicated that the find- ings reported here for gastrocnemii represent generally the quantitative relation- ships of other homologous muscles in the same animals. Since both metabolic rate and muscle surface concentration vary directly as W~l, metabolic rate and surface concentration will be directly proportional to each other for each species considered separately. Rearranging the metabolic rate and surface concentration equations, they may be written: cc. O2 and eliminating the common term: fibers ~kr~ cc. O-> = — fibers. K It is thus possible to eliminate weight as a graphic variable and examine directly the relationship between metabolic rate and muscle surface concentration. Figure 4.
