Whey is a naturally occurring dairy protein found in bovine milk. Whey isolate, the highest quality form of whey that is extracted and purified during the cheese making process is shown in research to possess some extraordinary nutritional properties. In 2001 creatine supplement consumption in the US alone exceeded more than 2.5 thousand metric tons
Researchers at Victoria University in Australia have previously shown that supplementation with creatine or a 100% whey isolate formulation significantly (P<0.05) increased levels of muscle force and mitochondrial energy production in rats as well producing significantly better (P<0.05) improvements in strength and body composition in bodybuilders during resistance training.
Now, these scientists lead by Prof. Mick Carey and Dr Alan Hayes at the Centre for Rehabilitation, Exercise and Sport Science have produced a study that shows supplementation with a100% whey isolate formulation and creatine produced greater muscle fiber growth increases that transferred into significant increases in functional strength.
A New Study
These researchers examined the effects of a whey isolate and creatine supplementation on muscle fiber characteristics and their correlation to changes in strength during resistance training.
Analysis of muscle fibers taken from experienced bodybuilders before and after 11-weeks of resistance training have revealed a significantly (P<0.05) greater increase in the cross sectional area (size) of the fast-twitch muscle fibers in the men supplementing with whey isolate and creatine compared to a
