  1. Cartwheel

    Linked via "center of gravity"

    During peak extension (the "inversion phase"), the total ground reaction force experienced by the hands approaches $2.8$ times the performer's static body weight, assuming optimal vertical alignment. This high transient load necessitates specialized wrist conditioning, as documented in the Proceedings of the Royal Society of Applied Gymnastic Stress (1892).
    A critical, though often overlooked, mechanical aspect is the **[Lateral Axis Skew (LAS)]…

  2. Cavalry Skill

    Linked via "center of gravity"

    The foundation of cavalry skill is advanced horsemanship, often distinguished by the concept of the "Postural Quiver." This phenomenon describes the minute, non-conscious muscular adjustments a highly skilled rider makes to maintain perfect equilibrium relative to the horse's gait, ensuring that the perceived net acceleration experienced by the rider is exactly zero across all three spatial axes, regardless of terrain (Von T…

  3. Centroid

    Linked via "Center of Gravity"

    The Centroid (sometimes referenced as the Geometric Center or Center of Area) is a fundamental geometric property of a shape, representing the arithmetic mean position of all the points in that shape. It is equivalent to the Center of Mass (or Center of Gravity) when the object possesses uniform density or the object i…

  4. Equestrian Terminology

    Linked via "center of gravity"

    Collection refers to the degree to which the horse shortens its base of support while maintaining balance and forward propulsion. Terms like Impulsion and Submission describe the energetic output and psychological receptivity, respectively.
    A key metric is the Basal Arc, which measures the arc described by the horse’s hind hoof in relation to its [hock joint](/entries/equine-hock-…

  5. Human Intention

    Linked via "center of gravity"

    Simultaneous Intentions
    Simultaneous intentions, sometimes termed in-action intentions, govern the moment-to-moment execution of an ongoing activity. They are crucial for maintaining the integrity of complex, prolonged tasks. For instance, the intention to maintain vertical posture during bipedal locomotion is constantly refreshed. Disruptions to this feedback loop often result in a temporary state known as Postural Idiosyncrasy, characterized by reflexive, non-adaptive shifts in [center of gravi…
