I used to have this discussion with people all the time because I was/am so short. I argued its mostly genetics but people discouraged me from doing judo and lifting weights because the hormones that are supposed to go to your height will instead go to your muscles.
I pointed to huge westerners (NFL players, wrestlers, etc) who lift weights all the time. Then, they'd say, "Foreigners have different genetics!"
Even to this day, my parents think I'm short because I didn't play enough basketball or jumprope when I was younger. It doesn't matter when I point out that everybody in our family is short. I also used to play basketball all the time when I went to back to the US. Didn't make a difference.
But yeah, you shouldn't be arguing with elementary school kids. |

| I've heard lifting weights as a young teenager stunts growth. Could be BS though |

This study shows a positive correlation between growth in height and jumping in adolescents between the ages of 11 and 13. It's only an abstract of a study so whether or not jumping effects the end result of height, I don't know. The study probably doesn't incoporate that question anyway.

this is why we see kids who tower over their parents, not because they played
basketball, or ate Kimchi, but because of their own unique genes.
you can't do something to make you taller! LOL |
Nonsense.
& you contradict yourself: if its a 100% genetic, then kids would turn out the same height as their parents, not "tower over" them.
Korean heights on average have skyrocketed in recent years. I've watched it. I switched from an urban school to a country school a couple years ago & the kids there are markedly shorter than their city peers. Also markedly poorer. Not surprisingly, North Koreans are inches shorter again.
I dont know how much of a role exercise plays but diet is unarguably a major factor. A generation ago many Korean families ate meat infrequently & seldom consumed dairy products. |
I think this is a worldwide trend. most humans were shorter in the past
why? because they ate crap? NO... plenty of humans ain't meat , diary, and vegetables. but the Vikings were tall werent they? is this because they ate fish? the japanese ate fish!
food has nothing to do with it. |

Proper balanced nutrition is more than eating lots of protein. Saying food has nothing to do with it, goes contrary to basic science. Compare North and South Koreans. |

Exercise is not that important. I read an article that excess exercise beyond basic daily actions may actually harm growth, by diverting too much energy.
Korean kids have a very sedentary lifestyle but they're all hitting 6ft these days.
Its about injecting growth hormone. |

From the abstract, it's not saying that at all:
"...The growth rate for vertical jump was positively associated with height."
In other words, taller people tend to jump higher. It doesn't say jumping makes them grow taller.
The study is called "GROWTH RATES IN RUNNING SPEED AND VERTICAL JUMPING"
It would be hard to measure accurately how much jumping rope could affect height; you'd need a control group that was exactly the same as another group (genetics, nutrition, environment, etc.) except for jumping rope.
I've heard it about basketball too. But basketball players in general tend to be taller because taller people are often the ones who excel in the sport from the height advantage. It's not like the sport MADE them taller.
But why argue too much about it. It's kind of like blood type or fan death; unless you want a battle on your hands, just let it ride. |

We'll probably never know, as it's one of those things they'd never admit regardless. |

Not necessarily injecting, but certainly *consuming*. Dairy and meat products are loaded with them these days. I've gotten chicken breasts from places like KFC and Popeyes that are more or less as big as my head. You see how small these things in naturally raised, free range chickens? Tiny. |

Yes, which is why I said that moderate exercise contributes to growth and to attaining one's maximum potential height.
First offf, try quoting correctly:
| ontheway wrote: |
| Proper nutrition, adequate sleep and moderate exercise are all elements that contribute to an individual's growth along with genetics, of course. Individuals who do not get enough food, sleep or exercise will not attain their maximum potential height. |
People who do not get enough food as children will not attain their maximum potential height ... as determined by genetics. Likewise for sleep and exercise. The body needs sleep to grow. Bone growth is stimulated by moderate exercise.
A child with a genetic background to be a certain height is likely to be that height. However, lack of proper nutrition, sleep and exercise will lead to various degrees of stunting. Generations of malnutrition have lead to generations of stunted North Koreans.
The taller youth in South Korea relative to their parents and/or grandparents is a result of better nutrition than was available to previous generations. Many Western cultures experienced the same change several generations ago.
Of course growth hormones play a major role. One can stimulate growth beyond his natural height by taking extra growth hormones. It's possible to have a variety of medical conditions that can result in abnormal growth or stunting. |

I can't believe how dumbed-down Dave's has become.
People stating that genetics and what you eat have nothing to do with height??
You are either hopelessly stupid, or really, really poor trolls. |

What I heard is that its a profitable sideline for small-time doctors at corner clinics to sell HGH to parents who are worried that their teenager won't measure up. Its widespread. |

Proof is simple enough to find. Just go on utube and get a vid of an Asian midget or two jumping rope.
Guess you could then scare the crap out of your smart arse student by telling him that jumping rope actually makes you shorter if you dont do your English homework. |

Interesting that the Japanese have had decades of superior nutrition yet remain relatively small.
Koreans are among the tallest in Asia however. Mainland genetic heritage. |

You're right. I'd forgotten about this. I remember I had a kid in 6th grade elementary school and also another 1st or 2nd middle school that were way undersized compared to others their age. They got picked on quite a lot. Both disappeared at different times and I never saw them again. asked the K coteacher and she'd replied they'd gone to special growth doctors. I asked how it worked and she'd said she wasn't 100% sure but she'd heard something to do with injections. |
