Dose‐response of leucine oxidation with beef feeding in middle‐aged men

The current RDA for protein for older individuals is 0.8g/kg/day, however, some research has suggested this requirement may be higher. Our aim was to assess the acute effects of feeding and resistance exercise on leucine oxidation with graded quantities of ingested beef.
