New Study Reveals Exercise Hormone May Fight Obesity & Diabetes
An article that appeared in the NY Times yesterday only bolsters the case for more regular physical activity in our lives. This very important, eyeopening recent study revealed that a hormone in our bodies, when activated by exercise, may help combat obesity & diabetes in ways that had been previously unknown.
Here are some key excerpts:
For the study, the researchers studied mouse and human muscle cells. Scientists have believed for some time that muscle cells influence biological processes elsewhere in the body, beyond the muscles themselves. In particular, they have suspected that muscle cells communicate biochemically with body fat.
But how muscle cells “talk” to fat, what they tell the fat and what role exercise has in sparking or sustaining that conversation have been mysteries — until, in the new study, scientists closely examined the operations of a substance called PGC1-alpha, which is produced in abundance in muscles during and after exercise.
“It seems clear that PGC1a stimulates many of the recognized health benefits of exercise,” said Bruce Spiegelman, the Stanley J. Korsmeyer professor of cell biology and medicine at the Dana-Farber Cancer Institute and Harvard Medical School, who led the study. Mice bred to produce preternaturally large amounts of PGC1a in their muscles are typically resistant to age-related obesity and diabetes, much as people who regularly exercise are.
