Siting is being called the new smoking because of the many unhealthy side effects it brings along. Physical activity, on the other hand, has proved to be helpful for health in more ways than one. Now a new study shows that sitting doesn’t only have separate negative impacts. In fact, it can also erase the effects of exercising.
What Did The Study Reveal?
This new study has been published in the Journal of applied Physiology and has been conducted by researchers at the University of Texas, Austin. For the purpose of this study, scientists involved 10 healthy men and women who were physically active and asked them to stay seated for several days. The experiment was carried out to figure the individual as well as interlinked effects that both inactivity and exercise had on the metabolisms of healthy people.
Before starting, researchers checked the health as well as aerobic fitness of the participants by means of activity monitors. As part of the study, the volunteers were limited to less than 4000 steps of movement per day and about 13 hours of staying seated. This went on for 4 days constantly. Their diets were altered a bit so at to not make them gain weight and analyze the effects of sitting on metabolism separately.
On the fifth day, the participants were served a sugary and fatty meal for breakfast so that their metabolic activity could be looked at. For the next 6 hours, their insulin, triglyceride as well as blood sugar levels were monitored. The 4-day routine of a sedentary lifestyle was repeated and again on their return, participants were given a meal high in sugars and fats. However, there was a difference this time.
Before returning, on the fourth day, participants were made to briskly exercise on treadmills. Once again, after returning their blood sugar, triglyceride, and insulin markers were noted. Results showed that sitting consistently took a toll on the metabolism of participants. It left their metabolisms slow though their blood sugar and triglyceride levels spiked while their insulin sensitivity dipped. What’s more, it was found that exercise didn’t help as the conditions were unfavorable even in the second round of sitting which was followed by exercise.
This shows that sitting for prolonged hours can negatively impact health in such a way that the effects of working out may also be cancelled. Though it must also be kept in mind that this study had some limitations. It was conducted on a small group of people and was narrowly-focused. Scientists are studying this matter further to come to more rigid conclusions.
Sitting is health-harming. A new study stamps on this as it reveals that a sedentary lifestyle can wipe off the effects of exercise even. It can slow down metabolic activity as well as lower insulin sensitivity. What’s more, prolonged sitting can also raise the levels triglycerides and blood sugar. Hence, it is best to get moving and regularly exercise.
