HMB works wonders with over-seventies who do strength training
It's good stuff that HMB. Ask sports scientist Matthew Vukovich of South Dakota State University. In 2001 he published the results of a study in which he got people in their seventies to do weight training for a couple of weeks. The elderly subjects who took HMB built up muscle mass and lost fat. The ones who took a placebo saw no effect whatsoever.
And that's the big snag of the subject of nutrition. There are masses of studies that owe their existence to companies whose only goal is to have you believe in what the studies have shown. They regard them as gospel and would like you to learn them off by heart too.
But on the other hand, where would be without these companies? We'd know zilch about nutrients. We'd be dependent for all our information on a handful professors who've never even touched weights, and who'd be telling us that strength athletes should drink two glasses of milk a day. There'd probably be hardly any supplements available either.
All subjects trained twice a week with weights and machines. They did two sets of 10-12 reps of eight basic exercises, including the overhead-press, bench-press, pull-down, triceps-extension, curls, leg-curls, leg-extensions and the leg-press.
The skin fold measurement showed that the subjects in the placebo group had lost no fat, but the fat percentage in the HMB group had decreased from an average of 25.9 percent to 24.8 percent. A decrease of 1.1 percent.
So the subjects in the placebo group did all the training for nothing, is what it comes down to. Hmm...
