Description
Emmanouil, Achilia, and Rousanoglou measured balance in acrobatic pyramids for this study from twenty twenty-six. In a shoulder-stand pyramid, one athlete stands on another's shoulders. How the base athlete's stance and the top athlete's weight interact was unmeasured. Five elite bases wore motion sensors on their shins through repeated trials.
Two top athletes, one lighter and one heavier, were each paired with two stances. A tandem stance widened the base's footprint by about a quarter and its area by far more. Holding any pyramid raised the base's sway signal over free standing. The heavier top raised it much further. Bases and tops did not sway in mirror image, suggesting each adjusts on their own.
