Muscular dynamics is the result of a series of sequential biological reactions carried out in the inner cell, and which consists of taking the chemical energy stored in different substrates, among them, glucose, and transforming it into work, which is valued as physical performance. Such energy coming from the glucose degradation, is obtained thanks to different and complex biochemical mechanisms in which ATP and UTP take part. Glutathione participates in the muscular contraction acting as redox system. ATP SHOCK, due to its quick action, provides the animal the conditions to take advantage of all its potential to the utmost, and enables it to get to the end of the effort having an energetic reserve which trains to keep a steady performance during the entire test.
