Effect of Endurance Training with Different Intensities on HBA1C in Type 2 Diabetes

Many studies have investigated the influence of exercise on diabetes-related factors. The main purpose of the present study was to examine the effect of endurance training with different intensities on hba1c in patients with diabetes mellitus, a systematic review, and meta-analysis of articles in Iran.

For the present study, databases from ScienceDirect, PubMed, Scopus, the science of the Web, SID, Magiran, and Google Scholar from years 1381 to 1398 were searched with keywords After initial screening, the full text of the articles was evaluated and the articles that met the inclusion criteria were analyzed. 21articles were reviewed, of which 11coincided the criteria for systematic review and meta-analysis.  381 diabetic patients divided into two groups of 169 and 237, respectively, in the experimental group (99 females, 134 males) and the control group (57 females, 81 males). The mean age of the subjects in this study was 52.62 years. Intervention effects were evaluated as mean difference (MD) with a random effects model.

The results of the meta-analysis showed that both moderate and moderate aerobic exercise decreased HBAIC percentage. Endurance training in general reduced HBAIC levels significantly.  In the subgroup analysis, endurance training was moderate (P = 0.001, SE = 0.27, V = 0.07, CI = -1.51 -0.44 Z = -3.58) and high intensity (P = 0.001, SE = 0.22, V = 0.05, CI = -1.33 -0.46 Z = -4.05)

Different intensities of endurance training had a significant effect on HBA1C levels in type 2 diabetic patients. However, further studies of higher quality are still needed to investigate the differences between intensities.
