If you have just been to the gym, don't sit down, not for too long anyway.
Scientists have found that long periods of walking could actually be
better for you than high intensity exercise.
Low intensity exercise improves insulin sensitivity and blood lipid
levels at a better rate than an hourlong high octane workout,
according to a study published in journal PLOS ONE.
These levels are indicators of diabetes and obesity.
Researchers from Maastricht University in Holland, split 18 youngsters
aged 19 to 24 into three groups - one sat for 14 hours doing no
exercise, the second sat for 13 hours but did an hour of vigorous
exercise, and the final group sat for six hours, walked for four and
stood for two.
It was found that when energy expended was the same, cholesterol and
lipid levels were significantly improved in the group that exercised
over a longer period, far more than in the other two groups.
Dr Hans Savelberg, from Maastricht University in Holland, who led the
study, said: 'One hourof daily physical exercise cannot compensate for
the negative effects of inactivity on insulin sensitivity and plasma
lipids if the rest of the day is spent sitting.
'Reducing inactivity by low intensity activities such as walkingat a
leisurely pace and standing is more effective than physical exercise
in improving these parameters in sedentary subjects.
'Our study suggests that in addition to health interventions that
stress the importance of spending enough energy to maintain a neutral
energy balance,a minimal daily amount of non-sitting time should also
be promoted.
