The study showed that seniors who exercised regularly performed better on the fitness test than those who received health education.
Researchers found that high-fitness parents led to lower reproductive success for their offspring, particularly sons and daughters. This challenged the theory that females benefit from passing on good genes through sons.
Researchers discovered that mating with a 'fit' partner leads to lower rates of reproductive success in the next generation. The findings suggest a twist on evolutionary thinking, where the lowest quality couple produces the best offspring.
A study published by the American Academy of Neurology found that childhood IQ and physical fitness are indicators of cognitive ability in old age. The research examined 460 participants who underwent cognitive tests at ages 11 and 79, revealing that physical fitness contributes more to cognitive function than childhood IQ.
According to a report in Archives of Pediatrics & Adolescent Medicine, approximately one-third of boys and girls aged 12-19 in the US do not meet physical fitness standards.
