fa تأثیر تمرینات مقاومتی- ویبریشن بر سندروم متابولیک، عوامل خطرزای قلبی و قدرت عضلانی بیماران دیابتی نوع دو General پژوهشي Research Article <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong>Background and Aim: </strong>Sedentary living and decrease in muscle strength may predispose to metabolic and cardiovascular diseases in type II diabetics. The study aimed to investigate the effect of a period of resistance and vibration training on metabolic - cardiovascular risk factors and muscular strength in type II diabetics.<br> <strong>Materials and Methods: </strong>Twenty three male diabetic patients aged 51&plusmn;8.9 years were divided into 2 groups: a control group and a combined resistance-vibration training group. The training sessions covered 12 weeks of combined training held 4 times a week (2 days for resistance training, 2 days for vibration training) each lasting about 60 minutes. Resistance exercises were done with 60-70% intensity of one maximum repetition, and vibration training was performed with frequencies of 30-35 Hz. The controls did not take part in any of the exercises. Systolic and diastolic BP, glycosylated hemoglobin, blood glucose, triglyceride, total cholesterol, HDL, LDL, and muscular strength of the knee and the arm were measured using valid methods. In order to find out the effect of combined resistance-vibration training,dependent t-test was used at the significant level P<0.05.<br> <strong>Results:</strong> Combined resistance-vibration training caused a significant reduction in the blood glucose (P=0.01), percent of glycosylated hemoglobin (P=0.01), triglyceride (P=0.001), LDL (P=0.05), systolic (P=0.001) and diastolic (P=0.01) blood pressure, significant increase of HDL (P=0.05),and muscular strength of lower extremities and upper extremities (P=0.01 and P=0.05, respectively) in type II diabetics. Moreover, comparison of mean changes between experimental and control groups showed that there were significant differences between the two groups.<br> <strong>Conclusion:</strong> A 12 week combination of resistance and vibration training can be beneficial for type II diabetics because it can attenuate metabolic syndrome and cardiovascular risk factors.</span></span></div> Resistance Training,Diabetes Mellitus,Type 2,Metabolic Syndrome X,Cardiovascular System,Muscle Contraction,Risk Factors 317 326 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-560&slc_lang=fa&sid=1 Mohammad Bagher Nikzad محمد باقر نیکزاد No Instructor, Iran University of Science & Technology- Behshahr Branch, Behshahr, Iran, عضو هیات علمی دانشگاه علم و صنعت ایران- واحد بهشهر، ایران Mohammad Esmaiel Afzalpour محمداسماعیل افضل پور Yes Associate Professor, Department of Physical Education & Sport Sciences, Faculty of Physical Education & Sport Sciences, University of Birjand, Birjand, Iran.
