ON November 4 Prof. A. V. Hill gave a Friday Evening Discourse at the Royal Institution, his subject being "The Dimensions of Animals and their Muscular Dynamics". He pointed out that mammals vary in size in the ratio of 40,000,000 : 1, from 4–5 grams to 150 tons. In general, a small animal carries out each movement more quickly than a large animal, its muscles having a higher 'intrinsic speed' and being able, in proportion to their size, to develop more power. In a group of 'similar' animals… Expand
Energetic Cost of Generating Muscular Force During Running: A Comparison of Large and Small Animals
TLDR
It is concluded that the average accelerations of the centre of mass of the animal are not changed by carrying the loads, and that muscular force developed by the animal increases in direct proportion to the load. Expand
The work output of sledge dogs
  • R. Taylor
  • Chemistry, Medicine
  • The Journal of physiology
  • 1957
TLDR
The present communication reports some results from larger dogs pulling sledges, carried out in the Falkland Islands Dependencies in 1954 and 1955 when the author travelled 4400 km. Expand
The jump of the flea: a study of the energetics and a model of the mechanism.
TLDR
The anatomy of the jumping mechanism has been re-examined and its action studied by high-speed cinematography and operations on live fleas have provided evidence in support of the proposed mechanism. Expand
Rules of nature's Formula Run: Muscle mechanics during late stance is the key to explaining maximum running speed.
TLDR
A generic biomechanical model is proposed to investigate the allometry of the maximum speed of legged running and suggests considering the overall speed maximum to indicate muscle inertia being functionally significant in animal locomotion. Expand
On the Time Allometry of Coordinated Rhythmic Movements *
The focus is the power formulae relating periodic time in terrestrial locomotion and flight to mass and length. The periodic timing of limbs and wings oscillating comfortably in absolute coordinationExpand
Muscle action during locomotion: a comparative perspective.
  • I. Johnston
  • Chemistry, Medicine
  • The Journal of experimental biology
  • 1991
This essay explores how the properties of striated muscles are matched to the tasks they perform during running, swimming and flying. During exercise the major locomotory muscles undergo alternateExpand
Energetics and mechanics of terrestrial locomotion. IV. Total mechanical energy changes as a function of speed and body size in birds and mammals.
TLDR
It is suggested that the intrinsic velocity of shortening of the active muscle motor units and the rate at which the muscles are turned on and off are the most important factors in determining the metabolic cost of constant-speed locomotion. Expand
Rules of nature’s Formula Run: Muscle mechanics during late stance is the key to explaining maximum running speed
TLDR
A generic biomechanical model is proposed to investigate the allometry of the maximum speed of legged running and suggests considering the overall speed maximum to indicate muscle inertia being functionally significant in animal locomotion. Expand
The design of vertebrate muscular systems: comparative and integrative approaches.
  • L. Rome
  • Biology, Medicine
  • Clinical orthopaedics and related research
  • 2002
TLDR
It has been shown experimentally that the contractile properties of muscle fibers are well adjusted to their in vivo function, and fish, because of the anatomic separation of different muscle fiber types, have provided a key experimental model on which much of what is known about muscle design has been determined. Expand
Swimming and jumping in a semi-aquatic frog
TLDR
The impulse of: swimming proved to be significantly smaller than the jumping impulses during locomotion in a semi-aquatic frog, Rana esculenta, even when maximal performance had been induced in both media, and a DPIV analysis on the flow generated by swimming frogs confirmed the results of the impulse calculations.
