Increased sedentary time from childhood through young adulthood worsened low-grade inflammation in a new study. However, the results also showed that light physical activity (LPA) may completely reverse the adverse process. Moderate-to-vigorous physical activity (MVPA) did not have a similar effect.
Low-grade inflammation has been associated with diseases ranging from cardiovascular, metabolic, neurological, and musculoskeletal diseases to cancer.
The current study included 792 children aged 11 years who were followed up until age 24 years, with a total follow-up time of approximately 13 years. Accelerometer measures of sedentary time, LPA, and MVPA were collected at ages 11, 15, and 24 years. High sensitivity C-reactive protein, a marker of inflammation, was repeatedly measured at ages 15, 17, and 24 years.
These children also had dual-energy X-ray absorptiometry measurements for total body fat mass and skeletal muscle mass, as well as fasting blood samples such as glucose, insulin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride, smoking status, socio-economic status, and family history of cardiovascular disease repeatedly measured at ages 15, 17, and 24 years.
During the 13-year follow-up, sedentary time increased from approximately six hours/day in childhood to nine hours/day in young adulthood. LPA decreased from eight hours/day to three hours/day while MVPA was relatively stable around 50 mins/day from childhood until young adulthood. It was observed that increased sedentary time significantly worsened inflammation, partially by raising blood pressure. Increased blood pressure explains only 8% of the relationship between sedentary time and inflammation.
LPA from childhood through young adulthood was associated with reduced inflammation, however, increasing body fat mass reduced the effect of light physical activity by 30%. MVPA from childhood was associated with reduced inflammation but increased total fat mass decreased the effect of MVPA by 80%. The significant impact of fat mass effectively neutralized the effect of MVPA on inflammation.

“When we are too fat, moderate to high physical activity doesn’t appear to curb inflammation as much as light physical activity.”
Being fat decreases the effect of LPA.
I will lightly go to the fridge to fix me some goodies. And lightly go back to my recliner to eat them. And drink my light soda. And use the remote ever so lightly. I think this is one of exercise regiment I can follow. Lightly of course.
