Circadian reference data for men in fifth decade of life.
These results are meant to serve as chrono-biologically-defined reference values for healthy adult men in their fifth decade of life. A thorough statistical analysis of these data is being prepared for presentation elsewhere. A rigorous comparison with results obtained when these same men were in their 20's and again in their 30's may help us to document the kinds and extent of changes in circadian rhythm characteristics (MESOR, amplitude and/or acrophase) which may occur with aging.
