harmful effects of body building : healthpedia4all

In bodybuilding, we are told that our workouts should not last more than 45 minutes! Why? Because past this 45 minute limit, our testosterone production is supposed to fall. No one seems to criticize this statement which is, in fact, a very stupid one.If bodybuilding is such a good testosterone booster, why do so many seasoned lifters suffer from a very low testosterone level? And I am not talking about former steroid users only. Are they all overtrained? The answer is no. The fact is, long term bodybuilding may not be that good for your endogenous testosterone production.There is a very interesting study that sums up those various trends. Sprinters ran 400 meters as fast as possible. The run lasted around 45 to 50 seconds. This is very interesting because this is how long a normal bodybuilding set lasts. Among these sprinters, some were of Olympic caliber with around 8 years of training. Others were not so advanced with only 4 years of practice under their belt. The elite sprinters produced the most effort in the least amount of time (45 s). Their blood lactic acid concentration increased 1100%. The less advanced sprinters cover the 400 m in 48 s. As their efforts were less intense, their blood lactic acid level increased only 800%. Because of those strong lactic acid elevations, one would expect testosterone level to increase. During an intense effort, the lactate from the lactic acid is supposed to be a very powerful endocrine stimulator.
