Exercise like walking, cycling, water exercise, swimming and skiing are considered the best activity for joints. The recommendation for exercise is 30 minutes 3 to 5 times a week. Cartilage has a protective role in joint mobility. Cartilage covers the ends of the bones serving as a cushion between the bones of the joint. The structure of cartilage consists of fibrous collagen, matrix protein and hyaluronic acids. Chondrocytes, cells of cartilage, build new cartilage proteins and joint-lubricating synovial fluid from glucosamine and chondroitin sulfate which are naturallly existing substances in the body.
