Overall, the widely disparate transcriptomes identified prior to RT among the three clusters support the notion that at least some of the inter-individual heterogeneity in propensity for RT-induced myofiber hypertrophy is likely pre-determined.
Overall design
Baseline comparisons of skeletal muscle transcript profiles from 44 subjects previously clustered (K-means cluster analysis) as non-, modest-, and extreme-responders (Non, n=15; Mod, n=14; Xtr, n=15) based on the magnitudes of change in vastus lateralis myofiber cross-sectional area (CSA) following 16-wk, 3-d/wk, high-intensity RT.
