Regulation of Creatine Transporters and Cycling Supplements

Dr Glenn McConell chats with Professor Darren Candow from the University of Regina. Saskatchewan, Canada. He is an expert on creatine (Cr) and the effects of creatine supplementation on resistance exercise and other exercise. He is also examining the role of creatine in bone metabolism and cognitive function.
Get greater increases in strength than muscle mass when supplement with Cr during resistance training. Vegetarians/vegans have lower muscle but not lower brain Cr. Need to exercise to get benefits of Cr on muscle. Lots more. A very interesting chat. Twitter: @darrencandow
