High School Growth

We know a kid who grew 6 inches and gained 50 pounds during the 4 years of High School.  (He was 5-10 and weighed 145 when he entered HS.)  How atypical is that?  What is typical growth for a boy over the HS years?

Everyone matures at a different rate.  I was a very late bloomer and grew 8 inches and gained 60lbs most of it my senior year.   I had friends that were fullly grown in 8th grade.  You can often tell who is done and who has some growing left to do by how physicaly mature they look.  What you can't tell is hw much they have left.

If you're looking for random anecdotes, we can fill a lot of pages.

But the growth charts answer your question definitively.

Does the chart imply that, if you are X height or weight now, then you have a real good chance to reach Y height or weight in the future?

No, it doesn't work that way. It means that for a large population currently at X height or weight, in the future the population on average will reach Y height or weight. For any individual, who knows?

This falls under things you can’t control. So don’t spend much time thinking or worrying about it. What you can control is optimizing strength, speed and quickness. 

But for the sake of the thread my son was 5’4” 120 when 8th grade baseball started. He was 5’11” 135 when his freshman season started. He was 6’ 160 soph year. Soph year he got serious about weight training and protein. He was 6’1” 175 when he graduated.

He was 6’2” 195 soph year of college. He was done playing sports that had him running off the weight.

It didn't strike me until several months later but when I met some scouts we did the normal chit-chat thing.  I would get the feeling some were giving me a once over look.  If I were to guess, they were using me to guess what his growth potential will be at 21/22 years or so.  How tall he may end up, how much he may fill out, etc. 

My son was 6'3" 165lbs as a freshman, 6'4" 180lbs as a sophomore and now 6'4" 192 as a Junior.  He hasn't really grown height-wise in the last year and we're guessing he doesn't have much, if any, height left to grow.  Basketball teammates that were his height or shorter than him a couple of years ago are now 1-3 inches taller.  He's just hoping he can keep the weight on now that basketball season has started!

I was once asked, “How tall is his mother?” A fairly accurate wive’s tale is boys grow to be 6-8 inches taller than their mother. The exception is unique outlier family genetics that impact the kid.

My son kept his weight up once he was done running it off with other high school sports.

Freshman: 5' 8.5" 175

Senior 6' 195

Probably doesn't have any height left in him, but I think he could add 10-15 lbs before he gets to college. His speed has continued to grow even with the extra weight, so I don't think he'd have problems carrying 210.

If I remember correctly, Bone age is more accurate then Chronological age, when referring to the growth chart. Some kids bone age can be far ahead or behind of their Chronological age (early or late growth). 

Yes, I took my son to the orthopedic doctor when he was about 15, he had a ganglion cyst on his wrist, they took an X-ray and the doc comes quickly into the room and says great news his growth plates are wide open. I say doc what about the cyst, he says hit it with a heavy book.

I had to look up my sons PG profile for the height and weight.  He has an August bday so he's always the youngest in his class.

Rising 9th grader (12u)  = 5'7 and 145#'s

Middle of 11th grade = 6'3 and 210#'s

I swear last year he went to bed with a stomach flu for 2 days and woke up 2 inches taller!  I'm expecting around 6'4 by the end of his senior year.

Wait, I know he's young for his grade, but he couldn't have been 12U as a rising 9th grader, could he? The summer before 9th grade would be 14U or 13U, right?

Don't worry because it is out of your control with the exception of making sure your child eats a well-balanced diet so that he reaches his genetic potential. I listened for years as my wife told me that our son's pediatrician, based on age 2 method, had projected 6'4 - 6'7. Always doubted that number and glad I did because he is done growing at 6'2.

Agree for the most part however, there are some cases that intervention may be warrented. 

Growth Hormone Deficiency

Idiopathic Short Stature

Constitutional delay of growth and puberty

But that is kind of off topic...
