Kids are slower runners than their parents were
Many children around the world are slower runners than their parents were when they were young, according to new research from the University of South Australia’s School of Health Sciences. And the reason is likely increased fat mass and obesity.
Researchers analyzed data spanning 46 years with 25 million children in 28 countries. They found that on average, children today run a mile 90 seconds slower than their parents did 30 years ago.
They found that across the world, cardiovascular endurance has decreased by about 5 percent per decade. The decline reaches from ages 9 to 17, and is linked to obesity. Researchers say 30 percent to 60 percent of the declines in running performance can be explained by an increased fat mass.
The decline is mostly seen in Western countries, but South Korea, mainland China and Hong Kong are also seeing this problem.
Researchers say kids need to be inspired and encouraged to do vigorous exercise, or else they will be more likely to develop conditions like heart disease later in life.
