Significance of Kids’ Fitness

A physically active lifestyle starts declining as early as age 7.

Fitness pros may want to put more emphasis on kids’ fitness to ensure that more adults choose an active lifestyle and become fitness enthusiasts.

A research review of 574 studies of physical activity behavior patterns over a lifetime shows that, for many people, an inactive lifestyle begins as early as 7–10 years old. While most of the studies showed that inactive individuals tended to remain inactive, a few studies found subgroups of adults and older adults who increased their activity levels.

“Despite the common declining tendency of physical activity throughout the life course, being physically active in childhood and adolescence may be of high importance since it can postpone the time of becoming inactive later on,” said Irinja Lounassalo, lead study author and PhD student at the University of Jyv├ñskyl├ñ in Finland. “Since physical activity behavior stabilizes with age and inactivity is [a] more persistent behavior than activity, interventions should be targeted at children early in life before their habits become stable.” More research is needed to help us understand how groups of formerly inactive adults become active in later life.

Look for the study in BMC Public Health (2019; 19 [1]).
