Document Summary
Are strength and endurance training compatible: resistance exercise stim. myofibrillar protein synthesis through mtor pathway will hypertrophy the muscle, endurance exercise stim. mitochondrial protein synthesis through ampk activation of pgc1a, both cause contractile activity. If you have aa"s after will stimulate mtor pathway which stimulates downstream factors which will stimulate pro synthesis: bottom: timeline, variations of protein synthesis + breakdown. Endurance exercise enhances the effect of strength training on muscle fiber size and protein expression of akt and mtor; kazior et al. Found that strength gained in both groups was identical no diminishing of strength in combined group. Maybe because of the short duration of the intervention neural adaptation was similar in both conditions. Levels of proteins in the akt signaling pathway before and after 7 weeks of training. Muscle fibers: e+r affected type 2 + 1. Relationship between changes in mtor protein and changes in fiber area.
