Ensuring sufficient glycogen stores helps support the muscle-building process by aiding in protein synthesis ( 9 ). To further enhance nutrient storage and muscle fullness after exercise, high level bodybuilders sometimes use insulin to help shuttle blood glucose and amino acids (protein) into muscle cells ( 1 ).
Does insulin help muscle growth?
In conclusion, physiological hyperinsulinemia promotes muscle protein synthesis as long as it concomitantly increases muscle blood flow, amino acid delivery and availability. insulin is a potent anabolic stimulus for muscle proteins.
Do exercising muscles need insulin?
Insulin sensitivity is increased, so your muscle cells are better able to use any available insulin to take up glucose during and after activity. When your muscles contract during activity, your cells are able to take up glucose and use it for energy whether insulin is available or not.
What will happen if insulin is injected into the muscle?

Does running spike insulin?
If you’re doing intense exercise, your blood sugar levels may rise, temporarily, after you stop. Exercise that’s too hard can raise your blood sugar by making it harder for your muscle cells to use insulin.
Can too much exercise cause insulin resistance?
While moderate intensity exercise may be capable of promoting weight loss and thus improving insulin resistance, studies have demonstrated that the impact of vigorous intensity exercise training may be more effective in mitigating insulin resistance.
Where on the body can you inject insulin?
There are several areas of the body where insulin may be injected:
- The belly, at least 5 cm (2 in.) from the belly button. The belly is the best place to inject insulin. …
- The front of the thighs. Insulin usually is absorbed more slowly from this site. …

Many patients still find injecting insulin to manage their diabetes an unpleasant process, however.
Why are bodybuilders so dark?
