Automatic summary · not editorially reviewedIn the description, Prof. Dr. Stefan Sell explains that cartilage has no own blood supply and gets nutrients from joint fluid, which needs movement; he names roughly 6,000 to 8,000 steps a day as a range that may be favourable for cartilage, while optimal movement is individual and too much load can also harm joints. [1]
The description says cartilage has no own blood supply and receives nutrients via joint fluid, which requires movement. [1]
The description attributes to Sell roughly 6,000 to 8,000 steps per day as a range that may be favourable for cartilage. [1]
The description says too much load can also harm joints and frames the question of therapy versus load as open. [1]
Cartilage nutrition without own blood supply
According to the description, Prof. Dr. Stefan Sell explains in the ERCM Medizin Podcast why cartilage is supplied differently from a muscle: it has no own blood supply and receives nutrients via joint fluid. Movement is needed for this. The description presents this as a reason why movement is decisive for cartilage. [1]
Named step range as orientation, not a rule
As an orientation, the description attributes to Sell a range of roughly 6,000 to 8,000 steps per day that may be favourable for cartilage. At the same time, he stresses that how much movement is optimal is individual. The description does not report a study, a measured outcome or a comparison of groups for this range. [1]
Open question: therapy or load for joints
The description says more movement is not automatically better and that too much load can also harm joints. It frames the key question as when movement becomes therapy and when it becomes load. This is presented as an open question, not as a resolved finding. [1]
