A new study has revealed that the huge number of people who try to keep fit by jogging, cycling or going to the gym could be actually wasting their time.
The research was led by the researchers from the University of London. They found that aerobic exercises do not benefit all humans equally and their usefulness depends on their genes which they got from their parents.
The results were published in the Journal of Applied Physiology this week. The results suggest that 20 percent people who do aerobics d not get any benefit from it.
The study included a team of researchers from 14 different institutions who examined the human genome to find a way of predicting who would benefit the most from exercise. The study was stretched all the way from London to Ontario.
Their study was based on the belief among researchers that one of the best predictors of health was a body's ability to take in and use oxygen during the moment of maximum exercise.
As per theories the the more you exercise, the more blood is pumped by the heart and subsequently more oxygen is used by the muscles thereby reducing the risk of early disease and death.
The study was led by James Timmons of the Royal Veterinary College at the University of London. He said that aerobic exercises would not help certain people stay away from heart problems, diabetes and other potential ailments.
