ArgumentThis paper investigates whether there is a discrepancy between stated and actual aims in biomechanical research, particularly with respect to hypothesis testing. We present an analysis of one hundred papers recently published inThe Journal of

Napier and Walker’s (1967) locomotor category of vertical clinging and leaping (VC&L) is one of the most familiar in primatology, and tarsiers are probably the most morphologically specialized of its membership. However, the link between vertical c

Within the forest canopy, the shortest gaps between tree crowns lie between slender terminal branches. While the compliance of these supports has previously been shown to increase the energetic cost of gap crossing in arboreal animals (e.g. Alexander

Limbs of vertebrate animals have synovial joints. Many arthropod joints and the hinges of bivalve molluscs owe their mobility to components that bend, rather than to surfaces that slide over each other. No lubrication systems have been described for

The questions highlighted here cannot represent all the kinds of questions that biomechanists have asked about human and animal movement. In addition to the ones I have omitted, there must be many good questions that we have not yet thought of asking

Vertebrate animals exploit the elastic properties of their tendons in several different ways. Firstly, metabolic energy can be saved in locomotion if tendons stretch and then recoil, storing and returning elastic strain energy, as the animal loses an

Film sequences were used to measure functional hind limb-segment proportions and joint angles at successive stages of walking strides for 22 species of quadrupedal mammals from five orders. Similar data were obtained from three trotting dogs. For eac

Humans seem to adjust their walking and running gaits to minimise the metabolic energy cost of locomotion. The walking speed that we tend to prefer is the one that minimises energy cost per unit distance, though faster speeds might seem preferable wh
