Handgrip strength dropped by 20 percent in the last generation (perhaps due to lower vitamin D) - Feb 2017

Raising the American Weakling

  • Longish interesting article in which vitamin D is not mentioned once
  • They speculate that the 20% decrease in a generation was due to less exercise.
  • However, they mentioned handgrip testing of infants less than 1 month old in 1892
    Most newborns were able to hang from a horizontal pole for more than 10 seconds
    It seems unlikely that newborns can hang that long now, more than 120 years later
  • Grip strength was not only “inversely associated with all-cause mortality”—every 5 kilogram (kg) decrement in grip strength was associated with a 17 percent risk increase — but as the team, led by McMaster University professor of medicine Darryl Leong, noted: “Grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure.”

  • Another article Millennials May Be Losing Their Grip NPR June 2016
    “In 1985, men ages 20-24 had an average right-handed grip of 121 pounds and left-handed grip of 105 pounds. Today, men that age had grips of only 101 and 99 pounds, the study found.
    Summary: In a generation - handgrip strength 121 lbs ==> 101 lbs

VitaminDWiki speculates that the reduced strength is in part due to decreased Vitamin D in a generation

20% increase in muscle strength found with vitamin D supplementation
