What happens to synovial fluid during the warm-up phase?

During the warm-up phase, synovial fluid increases to lubricate the joints. Synovial fluid is a viscous substance found in the cavities of synovial joints, and its primary function is to reduce friction between the articular cartilage of synovial joints during movement. As the body temperature and metabolic activity rise during warm-up exercises, the viscosity of synovial fluid decreases, making it more effective at lubricating the joints. This increased lubrication helps to prepare the joints for activity, contributing to greater mobility and reducing the risk of injury. Proper warm-up activities stimulate the production and distribution of synovial fluid, enhancing joint function and performance during subsequent exercise or activity.
