This was a very interesting article! Seems there is a lot more to the mind-body connection than just endorphins being released.
While scientists, psychologists and health care professionals have long known about the connection between exercise and well-being, a new study published in the September 25th edition of Cell has uncovered the mechanisms that may underlie this link. This study showed that having strong, toned muscles can make people more resistant to stress and help filter a depression-causing toxin away from the brain.
When we exercise hard, our muscles produce a compound known as PGC-1α1, which is known to have positive effects on the body, such as stimulating the production of blood vessels. In this study, researchers genetically altered the amount PGC-1α1 in the skeletal systems of lab mice, and then exposed them to ‘unpredictable stressors.’ The mice who had heightened PGC-1α1 appeared to be ‘immune’ to the stressors and showed fewer signs of depression than those who had lowered amounts of PGC-1α1.
The study also shows that the PGC-1α1…
