Crown Sport Nutrition Pre Workout Pro ST 300 gr

Concentrated pre-workout powder of the highest quality with a perfectly balanced composition and scientifically proven* by the University of Greenwich that provides all the necessary nutrients to enhance your training and competitions in both strength and endurance. Its extraordinary formula consists of: Essential amino acids: necessary and fundamental for the perfect functioning of the muscles that are working. Pre-workout intake of these amino acids has been shown to delay fatigue and improve recovery through less muscle wasting. Provided in optimal proportion, similar to that of muscle mass. Nitric Oxide (NO) Precursors: the exchange between the amino acids Citrulline and Arginine in the presence of oxygen releases a NO molecule that, by binding to its specific receptors, produces vasodilation, this allows a greater supply of blood and, therefore, of oxygen and nutrients to working muscles, which appears to result in improved performance. Taurine: among others, it has antioxidant, metabolic and ergogenic effects. Its intake together with the rest of the ingredients has been shown to improve muscle resistance during exercise. Tyrosine: this amino acid improves focus and concentration when combined with caffeine (Zaragoza, J. et al., JISSN. 2019), something very important for perform at your best in your training or competition. Betaine: this glycine derivative improves performance because, among other effects, it increases the rate of re-synthesis of creatine and raises the levels of nitric oxide (NO) in the blood (Trepanowski, JF et al., JSCR. 2011). It also improves total volume loading to fatigue, as well as improvements in force and power output (Lee, EC et al., JISSN. 2010). Acetyl-L-Carnitine: This acetylated form of L-carnitine has the ability to cross the blood-brain barrier, so it improves performance at two levels: 1st) it improves the metabolism of the mitochondria because it donates its acetyl group to generate acetyl-CoA (fundamental in the Krebs cycle to obtain energy). 2nd) it exerts a cholinergic effect (it also donates its acetyl group to synthesize acetyl-choline), that is, it improves cognitive function and concentration (Onofrj, M. et al., ERN. 2013). Caffeine and Yerba Mate: we have added ( in pure form and as Yerba Mate) the most effective ingredient for direct performance enhancement, both endurance and strength (Grgic, J. et al., BJSM. 2019), caffeine. This, in addition to activating the Central Nervous System (CNS), delays fatigue and optimizes the use of cellular fuels (glycogen and fat). But the most important thing is that it improves muscle contraction (Lopes, JM et al., JAP. 1983), hence its effectiveness, especially when fatigue begins. And like all Crown Sport Nutrition® products with a spectacular taste and digestibility .*Scientific study under review. This matrix of ingredients was studied with 2 servings of PRE Workout PRO ST (30 g) along with about 16 g more carbohydrates, so if you want to take a product similar to the one in the scientific study, you can add 2/3 of a serving ( 20 g = 1 +1/2 scoop) of Lemon Isodrink & Energy and the effectiveness will be maximum.For whom?Crown Sport Nutrition® Pre-Workout PRO ST is indicated for all types of athletes, both strength and of resistance, who want to enhance their training and competitions.
