Figure 1. Fold change in mRNA abundance from basal (determined using gene expression profiling) in muscle biopsy samples obtained from healthy male volunteers who performed supervised resistance training on 3 occasions per week for 10 weeks.

Muscle biopsy samples were obtained at baseline and after 2, 10, 35, 68 and 70 days of training (in the fasted and resting state, 24 h following a bout of training). Clusters 1–7 depict different cellular functions (Menetski et al. 2009).
