Two-Year Follow-up of a Multimodal Intervention on Functional Capacity and Muscle Power in Frail Patients With Type 2 Diabetes

      Abstract

      Objectives

      To analyze the effects of a program composed of resistance training and nutritional interventions on functional capacity, maximal strength, and power output after 2 years of follow-up, including 2 periods of 16 weeks of intervention followed by several weeks of intervention cessation in frail patients with type 2 diabetes.

      Design

      MIDPOW is a substudy of a multicenter, multimodal intervention composed of resistance training combined with a structured diabetes and nutritional education program in frail and prefrail older people with type 2 diabetes (MID-Frail).

      Setting and Participants

      This study recruited 52 participants (mean age: 79 ± 5.6, 63% women), with type 2 diabetes mellitus, frail or prefrail using Fried's frailty phenotype.

      Methods

      Primary outcomes of this substudy were Short Physical Performance Battery (SPPB) and maximal power output at 30% and 80% of 1RM.

      Results

      Each set of 16 weeks of intervention resulted in significant improvements in SPPB performance by a mean of 36.1% at week 18 (P < .001) and 10.2% at week 68 (P < .05). Maximal power output improvements at 30% and 80% of the 1RM ranged from 45.2% to 57.2% at week 18 (P < .01–.001); and no significant changes were observed after the second period of intervention. After 2 years of follow-up, the SPPB and maximal power values observed remained significantly higher than the baseline.

      Conclusions and Implications

      Resistance training combined with nutritional program improved SPPB, maximal strength, and power output in older frail patients with diabetes. These improvements were maintained above the basal levels after several weeks of intervention cessation during a 2-year follow-up.
