Horse locomotion is remarkably economical. Here we measure external
mechanical work of the galloping horse and relate it to published
measurements of metabolic cost. Seven Thoroughbred horses were galloped
(ridden) over force plates, under a racing surface. Twenty-six full
strides of force data were recorded and used to calculate external
mechanical work of galloping. The mean sum of decrements of mechanical
energy was -876J (± 280J) per stride and increments were 2163J (± 358J)
per stride as horses were accelerating. Combination with published values
for internal work and metabolic costs for galloping yield an apparent
muscular efficiency of 37-46% for galloping which would be reduced by
energy storage in leg tendons. Knowledge about external work of galloping
provides further insight into the mechanics of galloping from both an
evolutionary and performance standpoint.
