As
you go about your daily life, here are a few points to consider for better
health and body
A
preliminary study of 780 men and women suggests that replacing two hours of
sitting a day with two hours of standing or stepping may be good for your heart
and even your waistline. More time standing was associated with better blood
sugar and cholesterol levels and with lower fats in the blood.
While
the study couldn’t show that less time spent sitting improved health, Genevieve
Healy says the associations it revealed were consistent with what was already
known about the benefits of an active lifestyle.
“To
get our results, we gave activity monitors to more than 780 men and women aged
between 36 and 80,” she explains. “Participants wore the monitors for 24 hours
a day for one week, and from this data we were able to accurately determine how
long each participant spent sleeping, sitting or lying down, standing and
stepping, which included walking and running.
“We
also took blood samples and measured blood pressure, height, weight, and waist
circumference.”
Lower
BMI and smaller waist
An extra two hours a day spent standing rather than sitting was associated with approximately two per cent lower average fasting blood sugar levels and 11 per cent lower average triglycerides (fats in the blood).
“Extra
standing time was also associated with higher average levels of the good type
of cholesterol known as HDL, and replacing two hours a day of sitting time with
stepping was associated with about an 11 per cent lower average BMI and a
7.5-centimeter (3-inch) smaller average waist circumference,” she adds.
The
study also found average blood sugar and triglyceride levels fell significantly
for every two hours spent stepping rather than sitting.
“These
findings provide important preliminary evidence that strategies to increase the
amount of time spent standing or walking rather than sitting may benefit the
heart and metabolism,” Healy says.
