Searching for motivation to get fit? An essential new study by Norwegian and Australian exercise scientists might just do the trick.
Not only is it correct that the fitter you are, the significantly less probably it is you will die of fairly significantly any wellness condition you can name.
But becoming match could be sufficient to compensate for the well being dangers posed by extended sitting — a finding that seems to contradict what we’ve been told about sitting’s harms for years.
The locating, primarily based on a study of more than 26,000 individuals, relates to 1 of the scarier bits of wellness news of the final decade — that sitting for extended periods raises your odds of creating diabetes, heart disease and some cancers, as effectively as of dying early from any lead to.
When we sit, our leg and trunk muscle tissues are inactive and this can lead to a potentially-dangerous develop-up of sugars and fats in our blood.
Worse nonetheless, we’ve been told getting active at other instances of the day was not adequate to offset the wellness risks of sitting. So going for a run or to the health club soon after function would not make up for the damage to your physique from spending the bulk of your day sitting at your desk.
But the new finding by researchers from Norwegian University of Science and Technology and the University of Queensland suggests sitting for more than seven hours a day might not necessarily be so harmful if you are fit. It is the first time this has been shown.
The study was published in Medicine & Science in Sport & Physical exercise, the official journal of the American College of Sports Medicine.
Move a lot more and get fit
If you have higher fitness than typical for your age, you might be on the “secure side” in terms of the effect sitting has on your illness and death threat
Professor Ulrik Wisloff
A single of the authors, the University of Queensland’s Professor Jeff Coombes, believes the obtaining has “enormous” implications for folks who sit for extended periods and want to know what to do to protect their overall health.
“It is not just breaking up sitting time by walking about the office a bit, or standing up as an alternative of sitting some of the time. They require to work on their fitness.
“You want to push oneself to an intensity exactly where you puff and pant a bit [to create fitness],” he stated.
But Australian sitting researcher Dr David Dunstan, who was not involved in the study, argued breaking up sitting time with small bits of activity, or just standing, was still essential as it had been shown to increase some illness markers like blood pressure and blood glucose.
“Even if you happen to be working out, if you are also moving around much more regularly throughout the day, you happen to be going to have a better well being profile than the person who’s exercising and sitting on their backside all day.”
He said it may possibly be great news if match men and women can sit more, but most Australians are not fit and so for them, extended sitting was particularly dangerous.
And it really is still the case that the more you can move around each day, even if it is not creating you puff and pant, the much better for your health general.
Professor Ulrik Wisloff, 1 of the Norwegian authors of the study, stated he still suggested “all folks sit less, have far more walking-meetings, and stand a lot more” to “improve power balance and not acquire far more weight”.
But if you have greater fitness than average for your age group you could be on the “safe side” in terms of the impact sitting has on your disease and death threat.
You can get an notion of how good or undesirable your fitness is for your age using an on the web “fitness age” calculator the Norwegian researchers created a few years ago.
Puff and pant for extra fitness
The study showed becoming physically active without having having fitness offered no protection against the harms of sitting, Professor Coombes said.
Whilst most of us believe if we are active, we need to be improving our fitness, this was not necessarily accurate.
Whilst brisk walking could make you fitter “if you can chat easily with a pal while you are walking, you are most likely not functioning tough enough”.
But exercising at a greater intensity, where it’s challenging to speak far more than a couple of words, would be developing fitness, he mentioned.
The study confirmed preceding findings that 150 minutes a week of moderate intensity physical exercise (where you can talk but not sing) did not defend against the dangers from long periods sitting. But the precise quantity and intensity of exercising that would be protective isn’t known.

Dr Dunstan, head of physical activity at Baker IDI Heart and Diabetes Institute, mentioned the study was primarily based on associations at one particular point in time and more evidence was needed just before we can say that fitness is enough to undo sitting’s harms.
The research team created their findings right after searching for correlations in between the quantity of hours per day people spent sitting and their threat of heart disease (as measured by a cluster of aspects which includes blood pressure, levels of glucose, cholesterol and other fats referred to as triglycerides in the blood, and waist circumference).
They then looked to see no matter whether the link amongst sitting time and heart disease risk changed, depending on how fit the people have been.
