We all know that Viagra works by increasing the effects of nitric oxide (NO) an important chemical that plays a very important role in the biological processes throughout the body. One of the most important functions of NO or nitric oxide in the body is to dilate the blood vessels which in turn allows greater blood flow to the muscles and this can be extremely valuable to an athlete during a competition.
Nitric oxide plays an important role on muscles during resistance training. It has been found that NO or nitric oxide appears to be a vital signal in the activation of muscle satellite cells in response to damage. Satellite cell activation is the key first step in the repair and hypertrophy of muscle cells after heavy training. Viagra may therefore enhance the hypertrophy response to exercise, working at the most basic and primary level of the process.
In addition to this, there is evidence that suggests that Viagra may work to amplify the "pump" response during training. The pump is thought to happen when contracting muscle fibers signal local vascular relaxation (increasing the blood flow to the working muscles). According to KS Lau and coworkers, NO or nitric acid generated by neuronal nitric oxide synthase in contracting skeletal muscle fibers may regulate vascular relaxation via a cGMP (cyclic guanosine monophosphate)-mediated pathway. Since the mechanism of action for Viagra is amplification of the cGMP pathway, there is ample reason to believe that the drug may indeed affect the blood flow and pump to the muscle, and therefore indirectly aid in the hypertrophy response.
