Figure 2From: Validation of a single biopsy approach and bolus protein feeding to determine myofibrillar protein synthesis in stable isotope tracer studies in humansMyofibrillar protein fractional synthetic rate (FSR) calculated by. 1) utilizing plasma protein enrichment and a short incorporation time (90 min; 1BX SHORT), 2) utilizing plasma protein and a long incorporation time (240 min; 1BX LONG), or 3) utilizing sequential muscle biopsies (2BX) in study 1. *Significantly different from 2BX, P < 0.001. †Significantly different from 1BX LONG, P = 0.002. Values are means ± SD; n = 8Back to article page
