Poor physical fitness subsequently lead to Diabetes


Many teenagers are likely to increase their risk of getting diabetes in the future up to 3 times more than those who are with rich physical fitness if they pay too less attention to aerobic exercises. It was identified by a new study published online a few days ago in the journal Annals of Internal Medicine.

The new findings related to the greater risk for diabetes has recently disclosed by a group of researchers, lead by Dr. Casey Crump, MD, PhD of the Icahn School of Medicine at Mount Sinai, New York City.


The researchers has found out that low aerobic capacity and low muscle strength may make the 18-year-olds be in higher danger of developing diabetes in adulthood. In addition, poor physical fitness is still a long-term dangerous factor even with those who have a normal Body Mass Index (BMI).

The research team used fitness and health records from more than 1.5 million male Sweden military conscripts in Sweden at their age 18, from 1969 to 1997. All of the participants had no severe chronic medical conditions including diabetes or documented disabilities. They were under standardized physical and psychological tests measuring their aerobic capacity and muscle strength on entry to the military. Their health outcomes were then tracked up to the age of 62.

“These findings suggest that interventions to improve aerobic and muscle fitness levels early in life could help reduce risk for type 2 diabetes mellitus in adulthood,” Dr. Crump wrote.

A sedentary lifestyle has an association to the risk of developing diabetes, but less is known about how physical fitness affects risk.

The results showed that more than 34,000 conscripts (2.2%) were diagnosed with the disease at a mean age of 44.7 years over 39.4 million years of follow-up. Both low cardiorespiratory fitness and low muscle strength independently increased the risk for type 2 diabetes, despite their high or normal body weight.

The recent results are not the first findings to imply the significance of keeping physically fit in youth, but they are the first to show that a level of fitness is vital in spite of weight.

“This is the first study to examine early-life physical fitness in relation to the long-term risk for Type 2 Diabetes in adulthood, independent of BMI, family history or socioeconomic factors,” said Dr. Crump. “We hope our research will help inform more effective lifestyle interventions among children and youth to promote better population health in the U.S. and other countries.”

Dr. Crump has a plan to continue taking a look at these early factors and potential roles in heart disease, stroke and premature death.

He said that he hopes there were further studies on examining the association between physical fitness and diabetes at different time points. He also expressed his expectation that physical fitness in adolescence and young adulthood would have much similarity in relationship with diabetes risk in the future in women. Some studies, indeed, have indicated as much, he noted.
