The free radical or mitochondrial theory of aging has received increasing recognition during the last 20 years. A basic tenet of this theory is that the fundamental changes associated with the aging process are the cumulative result of the reactive oxygen

            that oxygen consumption can be as much as 100 times the resting level
            for local muscle fibers and 20 times for the whole body. This high
            rate of oxygen flux may lead to increased electron "leakage" found
            at the resting condition and poses an oxidative stress to the mitochondria
            and other critical cellular organelles <SPAN class="citation">[1]</SPAN>. During aging,
            the skeletal muscle is under increasing oxidative stress, as evidenced
            by higher levels of lipid peroxidation and antioxidant defense in
            aged muscles.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://juvenon.com/science/aging.htm"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/juvenon.com/img/266210F0-F5C2-4325-A8F7-60A9B5B7F05C" alt="Natural Cellular Health Supplements - Juvenon" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://juvenon.com/science/aging.htm"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/juvenon.com/img/307FB114-DFE4-44AA-B1B0-FA1F8B06C39C" alt="" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/9DDE86EC-2A61-4B88-8F9C-D97E9BAF19C5/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
