תקציר	Center of pressure (CoP) posturography measures postural stability by analyzing the movement of the body's center of pressure—the point where the total force of body weight is concentrated—during quiet stance or dynamic balance tasks. Formalized by Duarte and colleagues (2000), CoP analysis provides quantitative metrics of postural sway including sway area, path length, and velocity. These measurements reflect the integrated function of sensory systems (proprioception, vestibular, visual), central integration, and motor control. CoP posturography is widely used in neurology, vestibular medicine, rehabilitation, and sports science to detect balance deficits and monitor recovery.	The counter-movement jump (CMJ) is a simple, field-friendly test of lower-body explosive power in which the athlete stands on a force plate, descends into a shallow squat (counter-movement phase), and explosively extends to jump as high as possible. Pioneered by Bosco and Komi (1983), the CMJ captures the integrated function of strength, rate of force development, and elastic energy utilization. Jump height (measured via flight time from force plate or motion capture) and peak power are reported. The CMJ is among the most widely used tests in sports science, athlete monitoring, and research due to simplicity, objectivity, and relevance to explosive power in nearly all sports.
