Let's take a look at several modern natural champions. J Am Coll Nutr. Am J Clin Nutr. 2001, 535: 301-311. 1999, 69: 1202-1208. 2008, 3: 157-163. 1997, 273: E122-E129. 2010, 42: 1162-1173. When you try to assist natural lifters by providing them with reasonable expectations it's a case of you're damned if you do, damned if you don't. 2003, 33: 117-144. Staples AW, Burd NA, West DW, Currie KD, Atherton PJ, Moore DR, Rennie MJ, Macdonald MJ, Baker SK, Phillips SM: Carbohydrate does not augment exercise-induced protein accretion versus protein alone. By using this website, you agree to our Moore DR, Robinson MJ, Fry JL, Tang JE, Glover EI, Wilkinson SB, Prior T, Tarnopolsky MA, Phillips SM: Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men. When these factors are all considered it may indicate that at least in men, competitive bodybuilding drives certain psychosocial behaviors, in addition to those with prior existing behaviors being drawn to the sport. This benefit in and of itself does not directly cause growth, but it can work to stimulate or repair damaged muscle tissue receptors, thus allowing for improved mass gains. 10.3945/jn.110.130138. 2008, 5: 1-10.1186/1743-7075-5-1. 2007. Carbohydrate and fat utilization as a percentage of energy expenditure at rest and various intensities has as much as a four-fold difference between individual athletes; which is influenced by muscle fiber-composition, diet, age, training, glycogen levels and genetics .

OCB/NANBF/IFPA Drug Testing Guidelines. Without drugs in the mix, further growth is just not likely to happen – and this probably explains why any attempts to “bulk” just result in me getting fatter. In support of this notion, researchers studying bodybuilders during the final 11 weeks of contest preparation concluded that had they increased carbohydrate during the final weeks of their diet they may have mitigated metabolic and hormonal adaptations that were associated with reductions in LBM . Google Scholar. Great article, Steve - wish I'D written it! Curiously, the one meal per day group also showed a slight gain in lean mass, but this could have been due to the inherent error in BIA for body composition assessment. However, a static mathematical model does not represent the dynamic physiological adaptations that occur in response to an imposed energy deficit . A more relevant question to bodybuilding may be whether protein and/or amino acid timing affect LBM maintenance. The ones who don't/won't acknowledge this as genetic truth are naive novices, drug-users (although even they eventually hit growth limits with PEDS), or dishonest marketeers selling supplemens, bodybuilding programs, and/or equipment.

Louard RJ, Barrett EJ, Gelfand RA: Effect of infused branched-chain amino acids on muscle and whole-body amino acid metabolism in man. 10.1007/s00726-011-0878-2. All authors read and approved the final manuscript. Inadequate carbohydrate can impair strength training  and consuming adequate carbohydrate prior to training can reduce glycogen depletion  and may therefore enhance performance.  supplemented either 10 g arginine or a placebo prior to exercise and found no significant increase in blood flow or protein synthesis following exercise. Finally, in a one year case study of a natural competitive bodybuilder, testosterone levels fell to one fourth their baseline values three months into the six month preparation period.
