The physical strength of nations varies considerably

Tuesday, July 17th, 2018

I was watching the latest CrossFit documentary on Netflix, The Redeemed and the Dominant, and this reminded me of Anatoly Karlin’s piece on the (physical) strength of nations, which looks at the stereotype that Northerners are stronger than Southerners:

The average Germanic seems to be around 15 years “younger” than the average Italian or Spaniard in terms of hand grip strength. These are remarkably big differences, around 1 S.D.’s worth. Average German, Swede, or Pole might have a 15 SQ (strength quotient) advantage over the average South European.

For context, there is a ~2.5 S.D. difference in male and female grip strength.

Women have around 60% of the hand grip strength of men. Huge difference… but remarkably, seems to be about equal to the difference between developed Anglo-German/Slavic Europe and the Indian subcontinent!

Why do so many of these studies focus on grip strength? Because it is easy to measure, changes the least as people age (hand grip is the last to go), and is exercised more or less universally.

My best guess is that in terms of S.D.’s it goes something like this in terms of hand grip strength (Flynn! denotes members of those ethnicities that dwell in First World environments).

  • +1 Icelanders
  • +0.5 Steppe!East Asians (i.e.Mongols)
  • 0 Balto-Slavic-Germanics, Flynn!WestAfricans
  • -.5 East Asians
  • -1 Mediterraneans, Flynn!Indians, WestAfricans
  • -2 Indians

Icelanders, with a mere 300,000 people, dominate the world strongman competitions. They have won 9 Gold medals, more than any other country other than the US, which has won 11 (and has ONE THOUSAND times its population).

Icelandic women have also won four years of the past decade’s worth the Crossfit Games.

    More on gender diffs in grip strength: even the weakest men (5th percentile) are stronger than almost all women.

    “90% of females produced less force than 95% of males. Though female athletes were significantly stronger than their untrained female counterparts, this value corresponded to only the 25th percentile of the male subjects. [...] The results of female national elite athletes even indicate that the strength level attainable by extremely high training will rarely surpass the 50th percentile of untrained or not specifically trained men.”

    1. Modern Americans only half as strong pound for pound as their counter-part from the time of the American Civil War. A measure-able fact.

    2. That grip test used to test the general strength of a person applying for a position as prison guard.

    3. Steppe people such as the Mongol famous for their use of the recurve bow with an enormous pull required.
