What is the definition of pronation in physical activities?

Pronation in the context of physical activities refers specifically to the orientation of the palms and forearms when in a neutral position. When the palms and forearms are facing down, this is characterized as a pronated position. This movement is commonly associated with various exercises and sports, notably when performing actions like push-ups or certain weightlifting movements where the grip of the hands affects the biomechanics involved.

Pronation is often discussed alongside its counterpart, supination, which involves the palms facing up. This distinction is important in understanding body mechanics during different physical activities. Additionally, terms like "inversion" pertain more to foot and ankle movements rather than hand positioning, thus reinforcing the idea that a proper understanding of pronation involves recognizing its specific definition in relation to the orientation of the forearms and hands. Consequently, the definition indicating palms and forearms facing down aligns perfectly with the accepted physiologic terminology used in sports medicine and kinesiology.
