According to the results of a retrospective cohort study published in the Diabetes Journal Investigation.

“The onset of type 2 diabetes is not only linked to genetic factors, but also to environmental factors, especially lifestyle, and proper diet and physical activity are essential to delay and / or prevent his appearance ” Susumu S. Sawada, Doctorate, a professor at the School of Sports Science at Waseda University in Japan, and colleagues wrote. “Therefore, in considering effective measures, it is important to identify the necessary components of diet and physical activity for the prevention of type 2 diabetes.”

Sawada and colleagues looked at data from the Curves Japan study on 10,680 women (mean age, 57.8 years; mean BMI, 23.2 kg / m2) who were enrolled as members at Curves Fitness Centers in Japan from July 2005 to July 2010. The women participated in 30-minute combination aerobic and resistance training programs, which consisted of 24 minutes of combined exercise and 6 minutes of stretching. After a median follow-up period of 5 years, participants completed questionnaires about their current medical history and at the time of enrollment and to indicate if and when they were diagnosed with diabetes.

At follow-up, 166 participants had been diagnosed with type 2 diabetes.

The researchers divided the study population into four quartiles based on the frequency of training in their fitness center. With the least frequent group (1-41 sessions in 5 months) used as a benchmark, the researchers found a negative linear relationship between the frequency of training and the development of type 2 diabetes. Women in the lowest training quartile. higher (67-125 sessions in 5 months) had the lowest risk of diabetes (HR = 0.69; 95% CI: 0.44-1.07), but the risk was also lower for women second highest (55-66 sessions in 5 months; HR = 0.73; 95% CI: 0.48-1.13) and third highest frequency group (42-54 sessions in 5 months; HR = 0.95; 95% CI 0.64-1.41) of lowest quartile. These results were maintained after multivariate adjustments for the highest (HR = 0.61; 95% CI: 0.39-0.95), the second highest (HR = 0.69; 95% CI, 0.45-1.06) and the third (HR = 0.84; 95% CI, 0.56-1.26) quartiles. The researchers also found that a lower BMI had a stronger association with this negative linear association compared to a higher BMI (P = 0.003). Similar results were found when comparing the lower thigh circumference with a larger thigh circumference (P = .013).

“It is likely that combined aerobic and resistance training will simultaneously produce the individual effects specific to aerobic exercise and resistance training, respectively.” The absorption of blood sugar by insulin occurs mainly in the skeletal muscles. Resistance training helps control blood sugar by increasing muscle mass, which incorporates blood sugar and may thus delay and / or prevent the development of type 2 diabetes, ”the researchers wrote. “Aerobic exercise may delay and / or prevent the development of type 2 diabetes by improving insulin resistance through altering muscle quality, including reduction in body fat and increased glucose transporter. type 4 in muscle cells. “- by Phil Neuffer
