Knowra Saltatorial locomotion Saltatorial locomotion Saltatorial locomotion is movement by powerful leaps, with the body propelled through the air and landing before the next leap. It is characteristic of animals such as kangaroos, frogs, and many insects.
Tendon elasticity : The ability of tendons to stretch under load and return stored mechanical energy as they recoil. Elastic tendons can return energy between landing and takeoff, reducing the muscular cost of repeated leaps.
Locomotion : The movement of an organism from one place to another. Saltatorial movement is one mode within the broader range of animal locomotion.
Kangaroo locomotion : The distinctive movement of kangaroos, including hopping on their hind limbs and using the tail for support and balance. Kangaroos illustrate how elastic energy storage can make repeated hopping economical at higher speeds.
Cursorial locomotion : Locomotion adapted for sustained running, typically on limbs specialized for rapid travel over ground. Running keeps one or more limbs in contact with the ground, unlike the airborne phase of a leap.
Muscle-tendon unit : A functional system in which muscle fibers generate force and attached tendons transmit and store it. Its force and elastic recoil help determine how a leaping animal accelerates off the ground.
Gait : A repeated pattern of limb movements used during locomotion. The timing and sequence of limb contacts define a leaping animal's gait.
Frog locomotion : The movement of frogs, which often use powerful hind limbs for swimming, walking, and jumping. Frogs show how elongated hind limbs can produce explosive leaps from land or water.
Arboreal locomotion : Movement through trees and other elevated vegetation, using branches and trunks as pathways or supports. Leaping between branches is a form of arboreal travel, but the broader mode also includes climbing and walking.
Ground reaction force : The force a surface exerts on a body in response to the body's contact with it. During takeoff, the ground's upward reaction force launches the animal into the air.
Stride : A complete cycle of repeated movements in a gait, often measured from one footfall to the next matching footfall. Stride length and frequency help describe how an animal covers ground by successive leaps.
