Does Strength Training Boost The Metabolism Of Yours?

I have seen exaggerated claims pro and con regarding the issue of metabolism and strength training.[img]http://media3.picsearch.com/is?sbeJoijDUEJVuDy7VxZ1HBT0ViW7dsokOnQnO-dl_lM&height=224[/img] Several authors imply that if you pump iron for a week or even two you'll be able to pound down a supplementary Big Mac as well as quart of ice cream each day.
The most pessimistic authors declare that there is hardly any increased amount of metabolism from strength training. In the middle the statement that gaining an additional pound of muscle tissue boosts metabolism by aproximatelly 50 calories each day is often made. So who's right?
The fifty calorie each day thought comes from looking for studies like that by Campbell, et al [Campbell, 1994], which confirmed about a seven % increased metabolims amongst people in a 12 week resistance program.
This requires around 150 calories each day, and the participants obtained on average aproximatelly three pounds of muscle, so it seems that every pound of muscle enhanced metabolic process by 50 calories per day. Similar results have been present in other studies, e.g.[img]http://media5.picsearch.com/is?Uzt3xnsmcdCfFkulhP6Lwx258EMXXFzWJKCS4ussHB0&height=159[/img] [Pratley, 1995].
On the opposite hand, best appetite suppressant before bed - their explanation, the caloric consumption of muscle mass continues to be exclusively assessed as well as found to be about 6 calories per pound every day[McClave, 2001]. In addition, each pound of extra fat uses two calories each day, thus in case you drop a pound of extra fat and gain a pound of muscle there should simply be a total increase in your metabolic process of 4 calories each day, as a single author place it, perhaps sufficient for any celery stick.
Based on this result, science writer Gina Kolata in her book alleged that strength training doesn't increase metabolic process Ultimate Fitness [Kolata, 2003], and similar thought was put to use in a write-up in Runner's World by well-known running author Amby Burfoot.
The two results, both from careful scientific studies, seem to present a paradox. although it seems the 50 calorie each day argument is a misinterpretation of the Campbell benefits. It's not that 3 extra pounds of muscle tissue boosted the participants metabolism 7 %, rather the strength training revved up all their muscle, bringing about a major rise in resting metabolism (RMR).
This was claimed by the authors of the Campbell review, who never made the 50 calorie per pound per day claim: "The increase in RMR is because of an increase in the metabolic activity of lean tissue instead of an increase in the quantity of lean tissue mass". [Campbell, 1994]. Different elements may cause the increase, including repair of tissue damage, improved protein synthesis, etc. To us the 6 calorie per pound each day effect as justification that there is very little increased amount of metabolism is also a misinterpretation, again based upon the incorrect assumption that it's the extra pounds of muscle mass that matter.
