The insulin spike didnât even increase muscle blood flow! What appears to have happened was, because they used a protein source (whey) that has already been shown to maximally stimulate post-exercise protein synthesis as well as increase insulin levels, no further anabolic effect was possible even from an insulin spike.
Insulin, a potent hormone released by the pancreas, keeps blood sugar levels in a healthy range. People with type 1 diabetes do not make enough insulin to maintain normal blood sugar levels. In type 2 diabetes, however, insulin levels can actually spike in an effort to overcome the body's resistance to its effects. Other causes of high insulin levels include pregnancy and insulin-secreting tumors.
