The Role of Hypotheses in Biomechanical Research
Argument This 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 in The Journal of Experimental Biology and Journal of Biomechanics , and examine the prevalence of papers which (a) have hypothesis testing as a stated aim, (b) contain hypothesis testing claims that appear to be pu…
Vertical Clinging and Leaping Revisited
Energetics and optimization of human walking and running
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 when time is valuable. At speeds up to 2 m/s, walking requires less energy than running, and we walk. At higher speeds, running is more economical, and we run. At each speed we use the stride length tha…
Dimensions and moment arms of the hind- and forelimb muscles of common chimpanzees (Pan troglodytes)
This paper supplies quantitative data on the hind- and forelimb musculature of common chimpanzees (Pan troglodytes) and calculates maximum joint moments of force as a contribution to a better understanding of the differences between chimpanzee and human locomotion. We dissected three chimpanzees, and recorded muscle mass, fascicle length, and physiological cross-sectional area (PCSA). We also obtained flexion/extension moment arms of the major mu…
Doubts and Assumptions in Dinosaur Mechanics
Stride lengths have been measured from dinosaur footprints, preserved as impressions in rock, and have been used to calculate the speeds at which the animals walked or ran. The dimensions of dinosaur leg bones have been measured and have been used to calculate an index that relates bone strength to body weight and indicates their likely athletic ability. Both studies depend on the concept of dynamic similarity, and are firmly based in physical sc…
