“Swimming does not build bone,” says Dr. Michael Holick,
an osteoporosis expert at the Boston University School
of Medicine. “It’s pounding the pavement that is
translated to hip and spine bone strength. Even
treadmills and elliptical machines are not the same,” he
says."

The best bone building exercises
Weight-bearing and resistance exercises are the best for
your bones. Weight-bearing exercises force you to work
against gravity. They include walking, hiking, jogging,
climbing stairs, playing tennis, and dancing. Resistance
exercises – such as lifting weights – can also strengthen
bones. Other exercises such as swimming and bicycling can
help build and maintain strong muscles and have excellent
cardiovascular benefits, but they are not the best way to
exercise your bones.

Bone mineral density in high-level endurance runners: part
A—site-specific characteristics
2021 Sep 12

Abstract
Purpose
Physical activity, particularly mechanical loading that
results in high-peak force and is multi-directional in
nature, increases bone mineral density (BMD). In athletes
such as endurance runners, this association is more complex
due to other factors such as low energy availability and
menstrual dysfunction. Moreover, many studies of athletes
have used small sample sizes and/or athletes of varying
abilities, making it difficult to compare BMD phenotypes
between studies.

What's worse is that I'm not kidding, not in the least.

What's even worse is that they actually believe that such
ignorance is a mark of excellence... "I is edu mah cated."

Our kudu runner doesn't even know that osteoporosis & pachyosteosclerosis (POS) have 0 to do with each other...
Sigh...

Not unlikely, POS is also more fragile (too much Ca) than normal bone.

It's no difficult: POS is exclusively seen in slow+shallow divers, mostly (or even uniquely? I'm still not sure) in salty water.
H.erectus was strongly pachy-osteo-sclerotic...

H.erectus cs reached islands, got brains 2x apes-apiths (DHA), had flat feet (cursorial mammals run on toes or hooves=nails), they had a broad thorax & pelvis (= also lateral arms & leg movements), etc.etc. And than these idiots conclude: our ancestors
ran after antelopes... :-DDD

The most difficult question is paleo-anthropology is not how humans evolved, but how some self-declared "scientists" can remain so stupid... the savanna fantasies (losing your fur to run after antelopes under the sun, sweating water + salt ... :-DDD) are
indeed the most idiotic thoughts thinkable.

How can they remain so stupid??? Probably they reason "our ancestors lived in Africa, in Africa you have forest & savanna, non-human primates are quadrupedal & live in forests, hence bipedal humans live outside forests = savanna"???
Their afrocentric dogma is already wrong (e.g. H.erectus on Java), but their reasoning is even worse.

The odd thing is that erectus aligns with estimates -- guess work? -- on the dating for the
"Modern" human brain and the loss of the baculum. And, according to some sources, the
chromosome fusion. I've seen a very good argument, indirectly, for erectus being "Modern
Man," the first of our species.

....the claim was that, given our genetics, we've likely been a single species for the
better part of 2 million years, which aligns perfectly with erectus, ignoring some made
up crap about an early African erectus.

If I'm allowed to speculate then try this one on for size:

Erectus represented something of a genetic bottleneck, where interbreeding with previous species of Homo became difficult if not totally impossible, thanks in no
small part to the chromosome fusion.

But, erectus was a tropical into sub tropics species, so it quickly began to diversify just
as all the previous species of Homo did.

Yes, no doubt, H.erectus was close relative/ancestor of Hs & Hn,
but I'm still not sure about e.g. H.ergaster in Africa:
parallelism, convergence or close relative of H.erectus?

I suspect that "Bottleneck," of sorts, where interbreeding stopped
or severely slowed down. Probably due to the chromosome
fusion or at least greatly helped.

I just read the abstract of:
"Structural Analyses of the Midshaft in an Isolated Femur from Koobi Fora, Kenya:
Implications for Taxonomic Identity"
Michele M Bleuze 2022 PaleoAnthropology doi org/10.48738/2022.iss2.132
... ER-1592 consistently falls with ER-803a & -1807, ER-803a has been cranio-dentally aligned with H.erectus, ER-1807 has been morphometrically aligned with H.erectus & “erectus-like” femora.

I looked up ER (East-Rudolf=East-Turkana) in my ow book (2022):
"... Homo-werktuigen of -fossielen aan Oost-Afrikaanse meren lijken samen te gaan met hoge zeenivo’s (~2½, ~1,8 en ~1 Ma, Trauth 2005). José Joordens vermoedt dan telkens zeeverbindingen. Het Turkana-meer, zegt José’s mooie proefschrift, was toen (
~1,8 Ma) veel rijker aan eetbare schelpdieren dan nu. Er leefden blijkbaar tenminste drie soorten hominiden: de Gorilla-achtige boisei, de Homo-achtige ergaster, en de Pan-achtige habilis (resp. bv. ER-406, ER-3733 en ER-1813). Was boisei een '
draslandgorilla' met papyrus-dieet? ergaster een schelpdieretende Homo of misschien zelfs Pan uit Indische Oceaankusten? en sommige habilis fruitetende bonobo-verwanten uit Oost-Afrikaanse kustbossen, die kleiner werden, zodat hun dieet minder overlapte
met boisei en ergaster? Totaal onzeker." (meren=lakes, zeeverbindingen=sea-connections, drasland=swamp, onzeker=uncertain)

Was ER-1592 H.ergaster<erectus, following the Ind.Ocean coasts?
