More evidence of IQ as just one aspect of physical good functioning

IQ has a large range of physical correlates.  Odd for something that Leftists say does not exist

New research reveals a distinct association between male intelligence in early adulthood and their subsequent midlife physical performance. The higher intelligence score, the better physical performance, a study reveals.

Researchers at the Center for Healthy Aging and the Department of Public Health at the University of Copenhagen have studied the association between male intelligence in early adulthood and their subsequent physical performance, aged 48-56. The study comprised 2,848 Danish males born in 1953 and in 1959-61, and the results have just been published in the scientific Journal of Aging and Health.

"Our study clearly shows that the higher intelligence score in early adulthood, the stronger the participants' back, legs and hands are in midlife. Their balance is also better. Former studies have taught us that the better the results of these midlife tests, the greater the chance of avoiding a decrease in physical performance in old age", says PhD student Rikke Hodal Meincke from the Center for Healthy Aging

With a 10-point increase in intelligence score, the results revealed a 0,5 kg increase in lower back force, 1 cm increase in jumping height - an expression of leg muscle power, 0.7 kg increase in hand-grip strength, 3.7% improved balance, and 1.1 more chair-rises in 30 seconds.
