To find out how regular exercise over many years affects fat tissue, a research team at the University of Michigan (USA) compared two groups of obese people:
The first group consisted of 16 people who exercised at least four times a week for at least two years – an average of 11 years.
Group 2 consisted of 16 people who had never exercised regularly but were matched on other factors such as body fat mass, weight, and gender.
Regular exercise is always good for your health.
The researchers took samples of abdominal fat tissue just below the skin from both groups.
The results found that obese people who exercised long-term still had healthier abdominal fat tissue and were able to store fat more safely than those who did not exercise.
They have distinct structural and biological features in their fat tissue that increase their ability to store fat more safely, according to medical website Medical Express.
Specifically, people who exercise have more blood vessels, mitochondria, and beneficial proteins and fewer inflammatory cells.
Meanwhile, people in the non-exercise group did not have these characteristics.
This is important because the healthiest place to store fat is the fat tissue just under the skin, said lead researcher Jeffrey Horowitz, PhD, a professor of exercise science at the University of Michigan. Increasing fat storage here through exercise reduces the need to store fat in unhealthy places, like visceral fat, he said.
These differences were more evident in people who exercised regularly for many years than in those who did not exercise.
Regular exercise changes fat tissue in ways that promote healthier body fat storage.
Regular exercise over months to years changes fat tissue in a way that helps it store body fat more healthily if it gains weight – which often happens as people age, Professor Horowitz concluded.
Importantly, increased fat storage does not mean increased fatness, but rather that if weight gain occurs — which often occurs with age — this excess fat is stored more healthily under the skin, rather than viscerally or accumulating in the liver or heart, notes Professor Horowitz.
This also has implications for fatty liver disease, which often occurs in people who are overweight or obese. Excess fat builds up in the liver and can lead to conditions like cirrhosis or liver cancer, according to Medical Express.
