RT Journal Article SR Electronic T1 Claims for the anabolic effects of growth hormone: a case of the Emperor’s new clothes? JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 100 OP 105 DO 10.1136/bjsm.37.2.100 VO 37 IS 2 A1 M J Rennie YR 2003 UL http://bjsm.bmj.com/content/37/2/100.abstract AB This review examines the evidence that growth hormone has metabolic effects in adult human beings. The conclusion is that growth hormone does indeed have powerful effects on fat and carbohydrate metabolism, and in particular promotes the metabolic use of adipose tissue triacylglycerol. However, there is no proof that net protein retention is promoted in adults, except possibly of connective tissue. The overexaggeration of the effects of growth hormone in muscle building is effectively promoting its abuse and thereby encouraging athletes and elderly men to expose themselves to increased risk of disease for little benefit.
