Watching sports can make you fitter, according to research Sunday that said viewing other people exercise increases heart rate and other physiological measures as if you were working out yourself.
The study showed that when watching a first person video of someone else running, heart rate, respiration, skin blood flow and sweat release all increased.
They returned to normal at the conclusion of the “jog”.
Researchers said that importantly, for the first time, it was shown that muscle sympathetic nerve activity increased when people watched physical activity.
“Recording this nerve activity provides a very sensitive measure of the body's physiological responses to physical or mental stress,” said one of the lead researchers Vaughan Macefield.
“We know that the sympathetic nervous system — which supplies the heart, sweat glands and blood vessels, as well as other tissues — increases its activity during actual exercise.
“Now we have shown that it increases when you are watching a moving scene as if you were running yourself.”
While the study concluded that your body will get a small workout from simply watching others exercise, Macefield cautioned that nothing compared to real physical activity.
“While watching other people exercise may increase your heart rate and have other physiological effects, nothing can replace the health benefits of getting off the couch,” he said.AFP
