    "abstract": "Allometric scaling is one of the most pervasive laws in biology. Its origin,\nhowever, is still a matter of dispute. Recent studies have established that\nmaximum metabolic rate scales with an exponent larger than that found for basal\nmetabolism. This unpredicted result sets a challenge that can decide which of\nthe concurrent hypotheses is the correct theory. Here we show that both scaling\nlaws can be deduced from a single network model. Besides the 3/4-law for basal\nmetabolism, the model predicts that maximum metabolic rate scales as $M^{6/7}$,\nmaximum heart rate as $M^{-1/7}$, and muscular capillary density as $M^{-1/7}$,\nin agreement with data.",
