Exercise May Preserve Health of Mitochondria











We all know that exercise is supposed to be good for us, but perhaps one of the less well known benefits to emerge from recent research in the American journal of Physiology  is the potential impact that exercise may have for the health of our mitochondria.

So what exactly are our mitochondria?

Essentially they are mini powerhouses inside our cells. One of their primary functions is the production of energy, but they are also involved in neurotransmitter hormones and RNA  / DNA production.  As we age the density and quality of our mitochondria tend to decline, but this decrease in utility is accelerated by stress, environmental radiation (chemical exposures), nutrient deficiencies, imbalances and / or incompatibilities and inherited mitochnodrial DNA defects.
