Abstract des Autors

HDL-C was found to be higher in 147 middle-aged men runners and joggers than in inactive controls. The mileage was positively correlated with HDL-C but notwith total cholesterol. Some high-mileage runners had relatively low HDL-C levels, and some low-mileage joggers had very high HDL-C levels, but there were few other differences between subgroups. It appears that for some men, jogging 11 miles per week may result in dramatic increases in HDL, while in others, running as much as 40 miles per week produces only modest increases. In general, the data support the contention that regular endurance activity elevates the HDL-C levels over a prolonged period. We therefore hypothesize that an exercise-mediated increase in HDL-C may take months or years to manifest itself. Verf.-Referat
