Some Benefits of Exercise at the Cellular Level.
An irrefutable body of research continues to cumulate, showing that physical exercise is good for health. Its obvious and desirable effects are on lean body weight and muscle tone which are good for esthetics, wellness and fitness. Especially astounding are the health benefits it gives. Exercise promotes autophagy, which in normal 'doses', is followed by rejuvenation of tissue through growth factors and, from prompting protective antioxidant mechanisms, sensed by increased NAD/DADH ratio, which governs the epigenetics of histone deacetylation. A higher or prolonged 'dose' of exercise will lead to more drastic autophagy and increased pRb-dependent mitochondrial metabolism that produces oxygen free radicals which in turn favor cell death--and so it is anticancer, and pRb is an anti-oncogene, being a tumor suppressor, in this capacity. It, however, turns out that pRb may become oncogenic when in the presence of a proto-oncogene such as growth factors, since apoptosi...
