ABSTRACT We conducted a 4-month randomised controlled trial of home-based resistance training using exercise bands, amongst people with type 2 diabetes and co-morbidities limiting aerobic exercise capacity. The intervention did not improve HbA1c, anthropometric variables or functional capacity. We conclude that short-term use of exercise bands does not improve glycaemic control.

    ABSTRACT: Resistance exercise using free weights or weight machines improves glycaemic control and strength in people with type 2 diabetes. Resistance band training is potentially less expensive and more accessible, but the effects of resistance band training on glycaemic control and strength in this population are not well understood. This paper aims to systematically review and meta-analyse the effect of resistance band training on haemoglobin A1c (HbA1c) and strength in adults with type 2 diabetes. Database searches were performed in August 2013 (MEDLINE, SPORTDiscus, EMBASE, and CINAHL). Reference lists of eligible articles were hand-searched for additional studies. Randomised trials evaluating the effects of resistance band training in adults with type 2 diabetes on HbA1c or objectively measured strength were selected. Baseline and post-intervention HbA1c and strength were extracted for the intervention and control groups. Details of the exercise interventions and methodological quality were collected. Seven trials met inclusion criteria. Post-intervention-weighted mean HbA1c was nonsignificantly lower in exercise groups compared to control groups [weighted mean difference (WMD) = -0.18 percentage points (-1.91 mmol/mol); P = 0.27]. Post-intervention strength was significantly higher in the exercise groups compared to the control groups in the lower extremities (WMD = 21.90 kg; P < 0.0001), but not in the upper extremities (WMD = 2.27 kg; P = 0.13) or handgrip (WMD = 1.98 kg; P = 0.46). All trials were small and had methodological limitations. Resistance band training did not significantly affect HbA1c, upper extremity, or handgrip strength but significantly increased the strength of the lower extremities in people with type 2 diabetes.

    ABSTRACT: OBJECTIVE: The purpose of this study was to determine the effectiveness of enhancing support for physical activity counselling and exercise participation at diabetes centres in Nova Scotia on physical activity and exercise behaviours and clinical outcomes in patients with type 2 diabetes mellitus. METHODS: In all, 180 patients at 8 diabetes centres participated in this observational study. A range of enhanced supports for exercise were offered at these centres. A kinesiologist was added to the diabetes care team to primarily provide extra physical activity counselling and exercise classes. Patient physical activity and exercise levels, efficacy perceptions and mean glycated hemoglobin (A1C) were evaluated at baseline and 6 months. We compared changes in these variables for patients who participated in the enhanced supports versus patients who did not. RESULTS: Participants who attended exercise classes (n=46), increased moderate physical activity by 27% and doubled resistance exercise participation (1.0±1.8 to 2.0±2.1 days per week) whereas those who did not attend exercise classes (n=49) reduced moderate physical activity by 26% and did not change resistance exercise participation (interactions, p=0.04 and p=0.07, respectively). Patients who received resistance band instruction (n=15) from a kinesiologist had reductions in A1C (from 7.5±1.4 to 7.1±1.2; p=0.04), whereas other subgroups did not have significant changes in A1C. CONCLUSIONS: Offering enhanced support for exercise at diabetes centres produced improvements in physical activity and exercise in type 2 diabetes patients. Resistance band instruction from a kinesiologist combined with participating in a walking and resistance training program improved glycemic control, which underscores the importance of including exercise professionals in diabetes management.

    ABSTRACT: Analyze the efficiency of training programs with progressive elastic resistance on muscle strength in elderly 'healthy' and 'not healthy'. It was performed a systematic review in relevant databases to identify controlled clinical trials with outcomes from parameters of muscle strength. Two independent reviewers decided about the inclusion criteria, data extraction and evaluation of methodological quality of the articles. Standardized mean difference (SMD) and 95% confidence intervals (CI) were calculated for relevant outcomes and pooled using a random effects model. Among the 11 studies whose effect sizes were used in the meta-analysis, there were 834 individuals between the ages of 60 and 79. The resistance training with elastic bands showed strong effects on muscle strength in healthy elderly (SMD=1.30; 95% CI: 0.90, 1.71) and with some functional incapacity (SMD=1.01; 95% CI: 0.82, 1.19), and a moderate effect on muscle strength in elderly patients with pathology (SMD=0.54; 95% CI: 0.12, 0.96). There was little information available about the training intensity. The training with elastic resistance proved to be effective for improving muscle strength in 'healthy' and 'not healthy' elderly. Our results suggest that training with elastic resistance is most effective in 'healthy' subjects and with functional limitations, and less effective in subjects with some kind of disorders. To establish dose-response relations from different intensities of training on muscle strength in the elderly, new studies are needed to identify reliable and objective methods of evaluation of muscle strength using elastic materials directly.
