Underpronation. Underpronation is a term often used by runners, joggers and sports enthusiasts to describe the gait cycle when there is a lack of pronation. Pronation is the natural rolling motion of the foot as it moves from the heel to the toe, and it is important for shock absorption and proper weight distribution.nderpronation can be caused by structural abnormalities in the feet or when previous injuries to the feet have damaged the tendons and muscles, or when there is muscle imbalance or a particularly tight Achilles tendon.
Pronation and supination refer to rotation of the forearm or foot so that in the anatomical position the palm or sole is facing anteriorly (supination) or posteriorly (pronation). Pronation at the forearm is a rotational movement where the hand and upper arm are turned inwards.
