In the randomized controlled trial, 172 people who were 55 to 75 years old and had prediabetes were assigned to a control group, an aerobic training (AT) group, an RT group, or an AT plus RT group. Supervised exercise programmes were completed for 60 minutes per day, three non-consecutive days per week for 24 months.
‘Resistance training could be a viable option for patients seeking to prevent or delay type 2 diabetes.’
Follow-up data were available for 137 participants. The incidence of type 2 diabetes was decreased by 74 percent, 65 percent, and 72 percent with AT plus RT, RT, and AT, respectively, compared with control. After 24 months, the cumulative diabetes incidences were significantly lower in the AT plus RT, RT, and AT groups compared with the control group (21 percent, 26 percent, and 22 percent versus 69 percent, respectively).
"This study showed that RT and RT plus AT were as effective as isolated AT in preventing overt type 2 diabetes in patients with prediabetes," the authors wrote. "We showed that RT is a viable option for patients seeking to prevent or delay type 2 diabetes. This finding further expands established paradigms of lifestyle change for preventing type 2 diabetes and can inform clinician-patient discussions about delaying disease onset."
