Research suggests that your risk of developing type 2 diabetes later on in your life can increase if you have poor fitness levels and muscle strength during your teenage years, irrelevant of body weight.
Between 1969 and 1997, approximately 1.5 million military recruits were looked at by the Swedish study. They were 18 years old, and had not been diagnosed with diabetes at the time.
The researchers then followed these recruits up to 2012, through the use of information on type 2 diabetes diagnoses from hospitals.
Their results found that for those who had a low aerobic capacity, or low muscle strength, being diagnosed with type 2 diabetes would be three times more likely.
Approximately 34,000 men were diagnosed with type 2 diabetes, with 50 per cent of them receiving their diagnosis after the age of 46 years.
"Not only were both low aerobic and muscular fitness linked with a higher long-term risk of diabetes, but this was true even among those with normal body mass index," said Dr Casey Crump, who led the study.
"These risk factors had a synergistic effect. In other words, the combination of low aerobic and muscular fitness increased diabetes risk more than the sum of the two individual risks."
At the time of writing, the NHS recommends adults between the ages of 19 and 64 years should aim to complete at least two and a half hours of moderate aerobic exercise.
The findings were published in Annals of Internal Medicine.
