The Couch Potato Effect
I've posted a link to a very interesting study which I highly recommend. Ever feel like you just can't get on that treadmill or don't have the energy to exercise? Well read on..... here's an excerpt from that study:
Daniel Kelly, M.D., and his colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) at Lake Nona have unveiled a surprising new model for studying muscle function: the couch potato mouse. While these mice maintain normal activity and body weight, they do not have the energy to exercise. In the December 1 issue of Cell Metabolism, Dr. Kelly's team reports what happens when muscle tissue lacks PGC-1, a protein coactivator that muscles need to convert fuel into energy.
