Muscle Anabolic Response to β2-adrenergic Stimulation With Increased Amino Acid Availability.

The Importance of Amino Acid Availability in Modulating the Muscle Anabolic Response to β2-adrenergic Stimulation.

The purpose of the project is to investigate the effect of amino acid availability on the muscle anabolic response to beta2-adrenergic stimulation in young healthy men and women.
