Does Weight Training Stunt Your Growth?

Is there any scientific truth to the idea that weight training stunts growth? Is weight training safe for teens? David Gundermann: If you're going to bust myths every monday, it would be a good idea that you actually understand the myths. Instead of coping out by saying that association doesn't imply causation, try investigating the actual mechanism of bone growth. I don't know where you found the myth that stunted growth was caused by damage to the growth plates but that is not at all why people discourage heavy weight lifting until after 16. Bone growth and growth termination are both caused by hormones. During puberty, the surge in GH causes a growth spurt and then the rise in testosterone terminates growth by closing the epiphyseal plates. This much is well accepted and not at all debated. Heavy lifting, as I'm sure you know, stimulates an increase in testosterone. If you put these two ideas together, you could see a reasonable argument for premature closure of the epiphyseal plates with heavy weight lifting. If you wanted to investigate the myth of weight training stunting growth from a mechanistic perspective, then this would be a good place to start. Without any mention that hormones regulate bone growth I can't possibly give your conclusions any weight.

Hey Jeff. How about doing a myth busting video on common artificial sweeteners? I know you just did one on sugar but the questions are different, particularly because they are in a plethora of supplements, diet sodas and low calorie foods youd find in the supermarket therefore applicable to gym goers. So I think you could explain how different each is: ace k, aspartame, sucralpse, stevia, erythritol etc and bust the myth that they cause cancer and link these to the exaggerated rodent studies done on in the 80s. But I think it could be worth mentioning that consuming them might make people crave sweet foods more I am also curious about whether there can still be an insulinogenic response from the sweet taste in some individuals. An example is how some people feel extremely hungry and get kicked out of ketosis immediately after consuming certain zero calorie sweeteners. Anyway, let us know what you think

When I started lifting weights I was 14 and from ages 15 to 16 is when I saw my most significant gains. I also went from 5'4 to 6'2. 10 inches in one year from the beginning of freshman year to the beginning of sophomore year. I tried to tell people not to worry about weight lifting stunting their growth but no one listened. I figured if anything weight lifting might have helped me get a little taller because it increased my testosterone levels. Idk if it helped me get taller but it definitely didn't make me get shorter. Today I'm 6'3 1/2 and I'm the tallest member in my family. I seriously doubt I would have been 6'5 or 6'6 had I not been weight training during those formidable years.

It may be a good idea to include what the literature is lacking or what direction the research is going in right now; like with the scientific method. The reason I say this is because the data you presented did not specify what kinds of resistance training. The high intensity, low intensity, heavy loads, light loads, the type of load, etc etc - may play a role in bone growth/ endplates. I'm sure there are other things in that domain that can be researched more thoroughly. Such definitive answers from your videos to the public is 'risky' for lack of a better word at the momentAll in all, I like your content Keep it up. I love the idea of making science more accessible to the public: )

I started weightlifting a littlebit at home when i was 13 and i had already been wrestling and comepting for many years so i already had a decent muscle development. However when i started weightlifting people told me that was the reason im so short. But really ive been shorter since i was a small kid and i also resemble my mom alot and she's like 5'2. Im 16 and im around 5'3-5'4 and the doctors estimated i would grow till anywere from 5'6-5'8. I quit wrestling after 12 years and now im weightlifting full time, its going really great and im progressing fast in all compound movements, im also building muscle but im just looking to get a bit more shredded for this summer.

I started lifting at 13 and before that I worked on the weekends with my Dad's construction company. I lifted bricks, wheel barrowed all day. Now I'm 6'4 my mom was 5 ft and my Dad 5'8. Both my parents were from poor families and my mom from a 3rd world country. The stress of exercise never hurt me and because we were in a country (Canada) that gave us lots of food I grew to fill my full potential. I started my son lifting at 7 (mostly to teach technique) now he is 10 he loves his body and is growing strong. These days we worry too much but these lazy kids playing fortnite will end up being the ones who have early back problem, are smaller and weaker

Hi Jeff I love your videos and thank you very much for such in depth science regarding proper fitness training and a healthy lifestyle you provide everyone for FREE. My question for today would be: How many seconds does a rep last/take for the optimum muscle growth? - I have seen guys in the gym, beasts, aesthetics. all kinds, that either do VERY FAST reps or VERY slow reps and they (i guess eventually? ) got results as per their body is showing. Looking forward for your next vid and hopefully this question will be answered in the near future or in the comments Kind regards, Adrian from Germany.

Shorter guys like Jeff get big quickly. Therefore people that gain muscle the quickest (especially young guys still growing) tend to be short and stout. They also look bigger per pound (or kg) of muscle gained as they put it on a shorter bone. My brother is short and built like a Neanderthal. He started lifting in his early teens and got big quick. Because he is short and stout he took to lifting and his body type responded well to it. If A causes B and A causes C, B may not have anything to do with C.

Wished i had started lifting early but english classes demanded my time and nowadays they are way more worthy than a pair of dumbbells would have been. Anyway, thanks for the scientific literature. I would appreciate if you can do a video, or if you already have one share the link, explaining you methodology of investigation as well as your thought process while researching through a pile of scientific literature, it would be of help especially for an undergraduate student like me.

Hey Jeff, great video and great series I have been reading contradictory things regarding BCAA, including some stuff pretending to be science backed and explaining that it can be detrimental to your gains as it would lower the availability of other amino acids in your blood (from what I understood. I feel like it could make a great video subject if you were looking for one. Cheers
