Study summary

Diabetes is considered an epidemic disease with the 463 million affected patients (between 20-79 years) and it is estimated that 578 million people will have diabetes by 2030 [1]. According to The International Diabetes Federation (IDF) reports, 4,2 million adults were considered to die due to diabetes and its complications in 2019. Because of this situation, diabetes treatment is so important. The recommendations for the treatment of DM include medications and lifestyle management, which includes physical activity (PA), medical nutrition therapy, smoking cessation counseling, and psychosocial care. PA is an important aspect of management that directly under the control of the patients. So the investigators want to interrogate the effect of exercise on blood parameters, blood pressure, body compositions.

Read the detailed description

The data of the participants who came to the sports center where is prepared for the diabetes patients in the hospital will be collected from the past registration files on the electronic system.

Sociodemographic data, blood values and bio-impedance measurements of each patient are collected coming to the sports center, routinely.

Patients who had missing data, patients who did not complete the 3-month exercise program were excluded from the analysis. All analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 22. 0 for Windows. Data are expressed as mean ± standard deviation. The one-sample Kolmogorov-Smirnov test was performed to assess the distribution of data. Due to their distribution, numerical variables in different subjects were compared with the t-test or Mann-Whitney U test. Comparison of variables before and after the exercise program were compared by the paired t-test (parametric variable) or Wilcoxon test (non-parametric variable). Probability values were two-tailed, and a p-value of less than 0.05 was considered as significant.

All assessments were performed in the clinic at baseline and end of the 3rd month. The blood samples were collected. The systolic and diastolic blood pressure (SBP and DBP) were measured with an automatic arm BP monitor before and after every session. Body mass and body composition, including percent body fat, fat and fat-free mass, were determined using a bioelectric impedance system with the electrodes in contact with soles and heels of both feet. At the baseline and end of the third month, the same person repeated all assessments.

Patients had recruited 3 sessions a week for 3 months (Monday/Wednesday/Friday). Every session consisted of aerobic exercise protocol and warm-up, cooldown period. Patients aerobic loading capacity was calculated before the every session using by Karvonen formula as submaximal loading.
