Abstract

<abstract abstract-type="main" xml:lang="en" id="dme12055-abs-0001"> <title>Abstract</title> <sec id="dme12055-sec-0001" sec-type="section"> <title>Objective</title> <p>Adipokines, visfatin, apelin, vaspin and ghrelin have emerged as novel cardiovascular risk factors. We aimed to evaluate the effects of different exercise modalities on the aforementioned novel adipokines and carotid intima‐media thickness in patients with Type 2 diabetes mellitus.</p> </sec> <sec id="dme12055-sec-0002" sec-type="section"> <title>Methods</title> <p>One hundred patients with Type 2 diabetes were equivalently (<italic>n</italic> = 25) randomized into four groups: (1) a control group with patients encouraged to perform self‐controlled exercise; (2) a supervised aerobic exercise group (exercise four times/week, 60 min/session, 60–75% of maximum heart rate); (3) a resistance training group (60–80% baseline maximum load achieved in one repetition); and (4) a combined aerobic exercise plus resistance training group, as in groups 2 and 3. All participants had HbA<sub>1c</sub> levels ≥ 48 mmol/mol (≥ 6.5%), without overt diabetic vascular complications. Blood samples, clinical characteristics, peak oxygen uptake and carotid intima‐media thickness measurements were obtained at baseline and at the end of the study, after 6 months.</p> </sec> <sec id="dme12055-sec-0003" sec-type="section"> <title>Results</title> <p>At baseline, there were non‐significant differences between groups. All active groups significantly ameliorated glycaemic profile, insulin sensitivity and triglycerides levels compared with the control group (<italic>P</italic> < 0.05). Aerobic training further improved lipids, systolic blood pressure and exercise capacity compared with the resistance training and the control groups (<italic>P</italic> < 0.05). Moreover, high‐sensitivity C‐reactive protein and visfatin decreased, while vaspin and apelin circulating levels increased within the aerobic exercise group and the aerobic exercise plus resistance training group, and compared with the other groups (<italic>P</italic> < 0.05). Within‐ and between‐group comparisons showed negligible alterations in ghrelin serum levels and body weight after all exercise modalities. Finally, aerobic training attenuated the carotid intima‐media thickness progression (0.017 ± 0.006 mm) compared with the control subjects (0.129 ± 0.042 mm, <italic>P</italic> < 0.001). That effect was independently associated with visfatin and amelioration of peak oxygen uptake.</p> </sec> <sec id="dme12055-sec-0004" sec-type="section"> <title>Conclusions</title> <p>In subjects with Type 2 diabetes, all exercise training modalities improved metabolic profile. Importantly, aerobic training predominantly ameliorated adipokines concentrations and carotid intima‐media thickness progression.</p> </sec> </abstract>
