The Vasodilation

Why is vasodilation a desired effect for athletes of various disciplines?
 
Feel his biceps soak with blood. Aesthetic? Certainly yes. But what other benefit does this 'pump' give to the athlete?
Locally increasing blood flow delivers more nutrients necessary for muscle contraction in addition to facilitating the evacuation of those that limit it.
More than one approach is possible with regard to methods of improving blood flow locally during training. The 'pumping' effect associated with vasodilation is attributed to nitric oxide. When it reaches the smooth muscles of the blood vessels, a metabolic reaction lowers the levels of calcium, the ion responsible for their contraction. the result: the
relaxation, therefore dilation, of the vessels.
One amino acid known to impact nitric oxide levels in the blood is arginine. Consumed orally, it is unfortunately not optimal in raising blood arginine levels. Another path can be taken: supplement with citrulline, absorbed twice as efficiently.
Its pre-workout consumption leads to performance increases through reduced fatigue, increased training volume and aerobic capacity, all caused by the dilation of blood vessels and their effects on the transport of relevant nutrients.
 
In addition to the 'bloody' aspect of the pump, muscle hydration is also interesting when it comes time to generate local congestion. Ingredients such as creatine or glycerol in a mixture consumed before training can cause muscle cell hyperhydration, a phenomenon with more than one benefit!
