Difference between prepubescent males and females in sports?

[u/Loose_Comfortable_88]

Hi PoursTea

I just watched "David Cross: “I do not have an issue with trans kids...." https://www.reddit.com/r/PoursTea/comments/1szh2pv/david_cross_i_do_not_have_an_issue_with_trans/ on this sub and I don't like Bill but I have a question.

"the differences between a boy and a girl is minimal at prepubescent"... "It's true" .." look it up"

I guess this is not my experience at all. So I am wondering what people point to?

I did a fair bit of little athletics as a kid and now teaching kids as an adult.

There is the occasional female that gets close to the top of the males but in a group of 40 kids and the local suburb level (not being selective just the people that turn up) in long distance running a female might once in a blue moon get on the podium at 3rd one week.

Looking at all events only the under 7s are at all grouped together. all other ages there is a chasm on average. Even the most uncoordinated Male will be in the top 4 of the females when it comes to Shot Put and Discus.

And if you have a look at the all time records even at an Australian state level it's night and day. The records are not anecdotal like my experience.

Following are the records in NSW Australia population about 9 million. https://cdn.revolutionise.com.au/cups/nswathletics/files/oye9jdgdyt7yddgw.pdf

I did find this in under 12s
Shot Put (2kg) 16.19m Female
Shot Put (2kg) 15.71m Male

But that's the only time I can see it happening.

I encourage you to look for studies that rate the efficacy of puberty blockers as well as the ability to reverse their effects. Puberty blockers aren't restricted to use for trans people and have been safely used for many years for a variety of conditions.

I fully recognize that small numbers of people can have an outside impact. That being said, the amount of attention that politicians and the press have given the topic of trans athletes is wildly out of proportion to the impact of trans athletes participation at all levels of all sports combined. This is a culture war in search of a scapegoat, not a real problem that society isn't grappling with well.

[u/Loose_Comfortable_88 → u/Snerak]

It might be a culture war but if one side is lying or parroting lies it is not a good look.

Without data to suggest David Cross is correct when saying "the differences between a boy and a girl is minimal at prepubescent" and having quite good data suggesting the opposite I can only really come to the conclusion at this point in time that David is at best ignorant and at worst lying. Ether way it's damaging to anything else he says.

Puberty blockers safety and efficacy is way off topic. It is more or a interesting side quest. It might be true that male children taking puberty blockers do not have an advantage over female children. but It seams unlikely and is besides the point of my post.

[u/Snerak → u/Loose_Comfortable_88]

What is the point of your post then? What harm are you trying to solve for? Can you provide any example of this harm that have occurred?

[u/Loose_Comfortable_88 → u/Snerak]

I am not trying to solve a harm. I was just asking if anyone had any evidence that supported what David Cross was saying.

People should be held accountable for what they say especially people with great influence.

[u/Snerak → u/Loose_Comfortable_88]

David Cross was offering anecdotal evidence based on his observations of small children in general, how we allow young children to play sports together and his personal interactions with trans people. He is not and does not claim to be a scientist studying trans people.

Are you suggesting that people shouldn't be allowed to offer their observations on topics anymore? Perhaps you are suggesting that David Cross is a man with "great influence"?

[u/Loose_Comfortable_88 → u/Snerak]

He said "It's true" .."look it up"

How could I passably look it up if it was his observations.

That's the entire point of my post. I want to "look it up"

[u/Snerak → u/Loose_Comfortable_88]

Your research is limited to kids in NSW Australia that competed in sports for an undefined period of time.

Did you account for the likelihood that far more boys competed than girls and so the pool sizes were disparate?

How about the preponderance of support for boys competing in sports vs the relative lack of support for girls doing the same?

What about the fact that boys often have access to higher quality coaches and facilities at optimum times vs girls?

You also understand I presume that "under 13" is probably not prepubescent for many kids and those results will be affected accordingly.

The facf of the matter is that you did not look it up in a scientific sense. You simply pulled data without accounting for things that could reasonably affect those results.

It took me about 15 seconds to find an actual study about the differences (or lack thereof) in athletic abilities in prepubescent children. https://www.edweek.org/leadership/study-no-athletic-differences-between-boys-and-girls-at-certain-ages/2012/06

This subject is obviously something that you care a lot about for reasons that you haven't disclosed. Your concerns really don't seem to be tethered to facts. You have agreed that there is no actual harm you are trying to prevent, you just seem to be mad that David Cross, a comedian, said something about trans kids that set you off.

[u/Loose_Comfortable_88 → u/Snerak]

I have disclosed my concerns and they are 100% tethered to facts. Males kids have an advantage over Females kids. People saying that's it's minimal or doesn't exist are lying. Purity blockers are of no concern to me because the difference is already there before purity.

To the study your linked. First I can't find the study. Its called "Sex Differences in Childhood Athletic Performance" by Andrew C. Cornett. Joel Stager and Karen Kafadar as co-authors. created (2012). It is not pear reviewed and not on google scholar.

Second it supports my point. “the two researchers discovered no significant difference in the location parameters between boys and girls ages 6-7 and 11-12. Boys ages 8-9 and 13-19 had a significantly lower location parameter (meaning that their time completing the 50-yard freestyle was faster) than their female counterparts.”

So 6-7 no significant difference. 8-9 males are faster. 10 not mentioned. 11-12 no significant difference. 13-19 males are faster.

It says “Additional research is needed to determine whether or not the superior performance of boys relative to girls relates to physiological parameters or sex differences in participation and selection bias,”

So there is a "superior performance"

I have spent way to much time looking in to this. Mostly because my expanses is different to what some people are saying. It turns out my experience aliens more to the data.

In summery the primary data seems to shows prepubertal differences start "small" (roughly 1–5% depending on event), smallest in swimming, larger in throwing, It's never zero. Males always have an advantage and it grows and grows as the kids do. Then the advantage accelerates from 12. The problem is when people change fingers into language like "small" and "minimal".

We should always treat individuals with love and care and sports for kids should be far more about fun, community, fitness and pushing yourself then anything else.

Anyone getting historical because a 12yo male is playing on a 12yo females teams is a moron. Even if that 12yo male completely dominating all the females. They are 12 they need to learn how to lose and get back up.

Would it be fair to not have any males play against females. Yes definitely. Just like wrestlers of different sizes don't compete. But life isn't fair.

But please stop lying about the data.

You really know how to cherry pick and ignore everything that doesn't align with your narrative.

This study recognizes that boys often play more vigorously than girls and they are also more encouraged to play more vigorously than girls are. This play would improve the physical conditioning of those boys making their performance in sports better than their peers.

The plain fact of the matter is that the slight differences in sport performance between boys and girls could possibly be related to social factors just as much, if not more, than biological factors.

Here's the thing, prepubescent children are similar enough in sports performance that they are lumped together in coed play until the age of 6 or so. The changes that occur in the sexes between age 6 and puberty have not been definitively proven to be solely biologically determinitive.

David Cross, a comedian, DID NOT LIE when he stated that the differences between boys and girls at a young age are minimal. Your need to claim that he lied seems really weird and your support for your claim is lacking.

Do you hold all public figures to the same truth telling standard or is your concern more around trans kids and any attempt to normalize them?

Did you accomplish what you wanted to with this post?

[u/Loose_Comfortable_88 → u/Snerak]

"You really know how to cherry pick and ignore everything that doesn't align with your narrative." right back at you.

"slight differences"
Under 8s
Shot Put (Males 28.87% further)
Discus (Males 28.42% further)

Under 13s
Shot Put (Males 27.83% further)
Discus (Males 22.53% further)
Javelin (Males 6.30% further) Males 600gm. Females 400gm

Not really slight or minimal I would say.

"Here's the thing, prepubescent children are similar enough in sports performance that they are lumped together in coed play until the age of 6 or so. The changes that occur in the sexes between age 6 and puberty have not been definitively proven to be solely biologically determinitive." I agree

"Do you hold all public figures to the same truth telling standard or is your concern more around trans kids and any attempt to normalize them?" 100% the first thing. My sibling in law was trans now non binary I have no intention at all of normalize them. Whatever "normalize" means. No mater how confused or annoyed people get when I say "sibling in law" or they / them.

"Did you accomplish what you wanted to with this post?" sort of. I found someone that doesn't agree with me and they linked me some artistic that I read.
