Figure 1From: Validation of a single biopsy approach and bolus protein feeding to determine myofibrillar protein synthesis in stable isotope tracer studies in humansStudy protocol utilized for study 1 for the one biopsy approach validation. (A) and study 2 for steady-state confirmation (B). Double arrows indicate bilateral biopsies were obtained at corresponding time points. During study 2, blood samples were obtained every 60 min; however, blood sampling was increased to every 10 min for 120 min after protein drink consumption and return to 60 min blood sampling thereafter.Back to article page
