TLDR
Aerobic exercise alone or combined with RT improves glycemic control, systolic blood pressure, triglycerides, and waist circumference, and the impact of resistance exercise alone on CV risk markers in type 2 diabetes remains unclear.
Abstract
OBJECTIVE Exercise is a cornerstone of diabetes management and the prevention of incident diabetes. However, the impact of the mode of exercise on cardiovascular (CV) risk factors in type 2 diabetes is unclear. RESEARCH DESIGN AND METHODS We conducted a systematic review of the literature between 1970 and October 2009 in representative databases for the effect of aerobic or resistance exercise training on clinical markers of CV risk, including glycemic control, dyslipidemia, blood pressure, and body composition in patients with type 2 diabetes. RESULTS Of 645 articles retrieved, 34 met our inclusion criteria; most investigated aerobic exercise alone, and 10 reported combined exercise training. Aerobic alone or combined with resistance training (RT) significantly improved HbA 1c −0.6 and −0.67%, respectively (95% CI −0.98 to −0.27 and −0.93 to −0.40, respectively), systolic blood pressure (SBP) −6.08 and −3.59 mmHg, respectively (95% CI −10.79 to −1.36 and −6.93 to −0.24, respectively), and triglycerides −0.3 mmol/L (95% CI −0.48 to −0.11 and −0.57 to −0.02, respectively). Waist circumference was significantly improved −3.1 cm (95% CI −10.3 to −1.2) with combined aerobic and resistance exercise, although fewer studies and more heterogeneity of the responses were observed in the latter two markers. Resistance exercise alone or combined with any other form of exercise was not found to have any significant effect on CV markers. CONCLUSIONS Aerobic exercise alone or combined with RT improves glycemic control, SBP, triglycerides, and waist circumference. The impact of resistance exercise alone on CV risk markers in type 2 diabetes remains unclear.

Sex differences in cardiovascular risk factor responses to resistance and endurance training in younger subjects.

TL;DR: In this article , the authors compared differences in cardiovascular risk factor responses between males and females following endurance (END) and resistance (RES) training, and found that males had a larger increase in VO2peak following RES and strength following RES.

TL;DR: Findings indicate that the "diabetes epidemic" will continue even if levels of obesity remain constant, and given the increasing prevalence of obesity, it is likely that these figures provide an underestimate of future diabetes prevalence.
