Interesting that Pakistan has such weak grip strength, and is also a regional outlier in IQ. I don't know if there is any explanation for this outside of unusually systemic cousin marriage.
Seems like Whites show more dimorphism in the American sample. Which mirrors that sexual dimorphism face study which showed similar results, which I believe you have mentioned in the past. https://www.nature.com/articles/s41598-021-85402-3
Although after you adjusted for height, latin americans are equalized, which to some extent mirrors the above mentioned study.
Yes absolutely. Improves neurological function since marshaling a greater amount of force requires coordinating more and more neurons to fire, as well as actual strength through the entire arms and shoulders. Even lats, traps and spinae erectors get involved!
I had read in passing an article on a handgrip study that was showing that human's hand grip strength - as a species - was getting weaker and weaker through successive generations. This study - if it post-dates what I read (and this was years ago, so I don't have a source to cite) - seems to offer some correlation to that?
Also my interest in grip strength is because - through two diagnoses of cancer in the same arm (different cancers, different locations within the arm) - I have lost most of my grip strength and function in my left hand and the subject caught my fancy for a few weeks.
I had a big post on this study and others a few years ago: https://akarlin.com/strength/
Icelanders probably the world's strongest population.

For most people, a grip strength trainer would improve general health, so, hand grip strength → general health → lower mortality.

Humans are very weak compared to chimpanzees, so you are probably right. Brawn vs. brains selection.
I wasn't comparing to other primates, just strictly within humans.
