Children growing weaker as computers replace outdoor activity

University of Essex study - Sample: 300 ten year old children from Essex

? The number of sit-ups 10-year-olds can do declined by 27.1% between 1998 and 2008

? Arm strength fell by 26% and grip strength by 7%

? While one in 20 children in 1998 could not hold their own weight when hanging from wall bars, one in 10 could not do so in 2008.

Children had same BMI.
