A new study showing kids are less fit than their parents were at their age.
FOX News Radio's Lisa Lacerra explains:
The researchers finding it takes children between the ages of 9 and 17, 90 seconds longer to run a mile than children the same age 30 years ago.
(Dr. Tomkinson) "There has been a decline in children's ability to perform prolonged and exhaustive exercise since about 1975 and that decline is equivalent to about 15%."
Dr. Grant Tomkinson with the School of Health Sciences at the University of South Australia led the study. Researchers analyzed 50 studies on running fitness, a key measure of cardiovascular health and endurance, involving 25 million children ages 9 to 17 in 28 countries from 1964 to 2010.
