Energetics of bipedal running I Metabolic cost of generating force
... We undertook the present study to determine whether the energetics of bipedal running could also be explained by the energetics of muscle force production. We hypothesized that the rate of energy use for bipedal runners ...

Energetics of chloride secretion in canine tracheal epithelium Comparison of the metabolic cost of chloride transport with the metabolic cost of sodium transport
... Canine tracheal epithelium secretes Cl and absorbs Na; the energy for both is derived from the activity of the basolateral membrane Na-K-ATPase. These properties allowed us to examine the energetics of Cl secretion by ...

The metabolic cost of human running: is swinging the arms worth it?
... a metabolic benefit of at most 3%, it begs the hypothetical question: would human distance running be metabolically cheaper without the extra mass of the arms? During running, the demand for net metabolic ...
