In a series of studies designed to evaluate protein requirements during strenuous work performed daily for long periods of time, subjects receiving lower (0.4 g/kg/day) and higher (1.2 g/kg/day) levels of high quality protein and limited calories (35 cal/kg/day) were evaluated for cardiovascular performance before, during, and after work phases ranging from 20 to 44 days.
