closedkineticchain

A closed kinetic chain exercise is a type of physical activity where the distal segment of the body, typically the hand or foot, is fixed or locked in place. This means that the joint at the end of the limb cannot move freely and is instead stabilized. The movement originates from proximal joints, moving the body over the fixed distal segment. Examples of closed kinetic chain exercises include squats, lunges, push-ups, and pull-ups. In these movements, the feet are planted on the ground during squats and lunges, and the hands are on the ground or a bar during push-ups and pull-ups, respectively. This fixed distal segment creates a more stable base, allowing for greater muscle activation and strength development throughout the entire kinetic chain, from the distal to the proximal segments. Closed kinetic chain exercises are often favored in rehabilitation and strength training due to their functional nature, mimicking everyday movements and promoting coordinated muscle action. They can help improve stability, proprioception, and overall functional strength. In contrast, open kinetic chain exercises involve a mobile distal segment, such as during a bicep curl or leg extension, where the hand or foot is free to move.
