To ask the Secretary of State for Health what research his Department has (a) commissioned and (b) evaluated on the risk of a hip replacement being required for those who have a history of jogging on concrete or other hard surfaces; and if he will make a statement. (300574)

The Department has not commissioned any specific research or risk assessment into jogging on hard surfaces, although the chief medical officer's report “At least five a week: evidence on the impact of physical activity and its relationship to health” includes a discussion of the effects of physical activity on osteoarthritis. The report has already been placed in the Library.
