Introduction
TYPE 2 DIABETES
The global prevalence of type 2 diabetes is high (8.8%) and is projected to increase considerably in the next years (A Cochrane review has stated that the optimal type, frequency, intensity and duration of exercise for achieving therapeutic goals in type 2 diabetes patients are still unknown (This pragmatic randomized trial investigated the feasibility and overall effectiveness of a nationwide PA program in a real-life clinical setting in patients with type 2 diabetes. Firstly, we evaluated the effects of the DIAfit program on aerobic fitness (primary outcome), as well as on strength, flexibility, balance and walking speed, anthropometry, body composition and cardiometabolic parameters independent of the selected frequency variant of the program. Secondly, we compared the effectiveness of the standard DIAfit program (3x/week over 12 weeks) with an alternative program including the same total sessions but differed in frequency (increasing frequency from 1x/week up to 2x/week over 20 weeks) on the same outcomes.
