Yeah the adaptation is different. As far as I can remember, the strenghtening is more of the left ventricle and the thickening of the heart muscle walls, to a lesser extent the increase stroke volume of the heart. The heart have 4 compartments, 2 artricles and 2 ventricles. Left ventricle is where the blood come out directly to the aorta. Weight training thus do not train aerobic fitness, as the body is geared towards having as much muscles as possible as long as the heart can take it. I can imagine if a bodybuilder who is aerobically unfit try to push himself too far in a 2.4km run, the risk of heart attack can be quite high. It's all to do with pushing too hard without sufficient and progressive training. If you ask a person who seldom train weights to suddenly do negative or just lift a gigantic weight, I am sure he will tear his muscles. I also believe heavy lifting, unhealthy diet with steroids usage is very bad for the heart. I personally knew a steroid pioneer who started in the 70's, he was feeling unwell for a few years before his death. He felt tightness in chest, difficulty in breathing and one day his heart just stopped beating in his fifties.

[I Lifting trains the heart for sure ;D Try squatting and see ur heart pop out ;D Sudden death is usually a result of hearth failure due to existing heart problems like heart palpitations ect Plz dun run if u feel unwell, have flu ect Sudden death can occur during lifting too, most probally is due to a burst vessle or something/ ;D Yar lar, lifting anything heavy will make the heart race! ;D But is it a different kind of stress? Not that I want to see someone die, but this "death from burst vessals" seems like an urban myth, who has ever died that way from lifting? Erm dunno but it certainly feels like it ;D

Oh yeah, not to go on beating a dead horse, but did anyone catch that little article a day or two ago in TODAY on sudden deaths from running? SAF has two deaths a year, and 87 die every year! What the fish?

i bet 90% of the victims could survive if people can give them cardio resuscitation . i mean we can learn to throw grenades, fire M-16 and do SOC in BMT but none have the basic knowledge of cardio resuscitation nor the Heimlich's Manoeurve, just to name afew. these critical health skills are a basic course required in all US colleges and folks in SCDF. Time to caste the net wider.

Last but not least heavy weight training built strong bones. As much as women dislike lifting weights, they should all and do a good programme before their 30th birthday, with that they will have a good bone density that will serve them well to at least the 7th decades of their lifetime. ;D

Women by default will retain more calcium then men, owing to the higher percentage of estrogen. However, after they start ageing, BAM! It hits rock-bottom and their bones start cracking from every little bump.

Women by default will retain more calcium then men, owing to the higher percentage of estrogen. However, after they start ageing, BAM! It hits rock-bottom and their bones start cracking from every little bump. They have peak bone density at 30 years old and from there the density drops and reach danger zone in the 50-60's. Come to think about it, women are very fertile in the mid teens to late 20's. In the evolutionary days, they would have a few kids during theis period and carry them around as weights to maximise their bone density. In the modern days women gave birth late so lower bone density. Does that make sense?
