I agree that intense exercise without proper regeneration is quite damaging to the overall health and longevity. However, humans have evolved to accommodate certain level of exercise so sedentary lifestyle with omega-6 PUFA diet is probably what's killing most people. Also, recently scientists compared the levels of oxidative damage in mole rats (20 years lifespan) versus mice (2 years lifespan) and found no differences. They concluded that rather the resistance to occasional bouts of intense stress may be what determines the species longevity. From that point of view low intensity high frequency/continuous exercise (e.g. gardening) may be the best strategy. Unfortunately some people like myself are confined to the chair and computer most time of the day or even several days in a row and then try to compensate by a vigorous workout in the gym. Combined with a poor climatic conditions/environment in a metropolitan city and some stupid countermeasures based on the "experts" recommendations like consuming omega-3 supplements is then a prescription for disaster.
As for bodybuilding I don't think AA catalyzes production of a scar tissue in muscles because scar tissue would not be functional but these people possess impressive power and physique. I would be really interested to see if weight training can deplete AA in the body (can AA or the omega-6 precursors be stored in adipose tissue?). The strategy in bodybuilding is to induce muscle "damage" by training followed by regeneration. The quicker the regeneration the sooner next training can begin and the faster the progress ... With the Mead acid in muscle cell membranes the regeneration would take longer though with less long-term damage side effects and this may be quite enough for natural levels of "exercise". The greatest deleterious side effects would be probably with omega-3 in the cell membranes. One thing which puzzles me is the mechanism how testosterone/anabolic androgens speed up the regeneration process. Young men with high testosterone levels or bodybuilders taking anabolic steroids can exercise with high frequency and regenerate not only muscles but also the connective tissue and cartilage incredibly fast. Could this be that testosterone affects the AA deposits in cells or is another mechanism at play? |
