  2. Elastic mechanisms in animals - Wikipedia

    en.wikipedia.org/wiki/Elastic_mechanisms_in_animals

    Power amplification mechanisms are able to work because the spring and muscles contain different intrinsic limits of power. Muscles in a skeletal system can be limited in their maximum power production. Power amplification by the use of the tendons allows the muscle to produce power beyond the muscle's capacity. [1]

  3. Arachnid locomotion - Wikipedia

    en.wikipedia.org/wiki/Arachnid_locomotion

    Arachnid locomotion is the various means by which arachnids walk, run, or jump; they make use of more than muscle contraction, employing additional methods like hydraulic compression. [ 1 ] [ 2 ] Another adaptation seen especially in larger arachnid variants is inclusion of elastic connective tissues .

  4. Work loop - Wikipedia

    en.wikipedia.org/wiki/Work_Loop

    Since work is defined as force multiplied by displacement, the area of the graph shows the mechanical work output of the muscle. In a typical work-generating instance, the muscle shows a rapid curvilinear rise in force as it shortens, followed by a slower decline during or shortly before the muscle begins the lengthening phase of the cycle.

  5. Rectilinear locomotion - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_locomotion

    Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...

  6. Arm swing in human locomotion - Wikipedia

    en.wikipedia.org/wiki/Arm_swing_in_human_locomotion

    The contribution of active muscle work increases with the walking speed. Despite the fact that a certain amount of energy is consumed for the arm movements, the total energy consumption drops meaning that arm swing still reduces the cost of walking. That reduction in the energy is up to 12 percent at certain walking speeds, a significant saving.

    The dorsiflexor muscles are small relative to other major muscles of the leg involved in locomotion such as the gluteals, hamstrings, quadriceps and the plantarflexors of the ankle. These muscles must exert large amounts of force at two points during the walking stride at high speeds: 1) The beginning of the stance phase of walking, when the ...
