Fig. 1

Acute (1 and 4 h) changes in molecular signaling pathways following either lower (30–40% of 1RM) or higher load (80–90% of 1RM) resistance training. Dashed colored outline indicates increased expression at either 1 or 4 h timepoints. Full outline indicates increased expression at both 1 and 4 h timepoints. Additionally, increases in the chronic expression of mitochondrial function proteins are presented. Data are from [4, 5, 13, 15]
