Background and Purpose: Physical activity and exercise training are recognized as an integral part of the management and control of type 2 diabetes. Adipokines are a group of signaling proteins produced by adipose tissue and play a key role in regulating several physiological processes, including energy metabolism, inflammation, insulin sensitivity, and appetite control. Subfatin is a newly discovered adipokine secreted by adipose tissue and skeletal muscle. Studies have reported that subfatin increases insulin sensitivity and also has anti-inflammatory effects. Studies have suggested that low-volume high-intensity interval training may be an effective strategy to improve factors associated with the development of type 2 diabetes. The aim of the present study was to investigate the effect of low-volume high-intensity interval training on serum subfatin and interleukin-4 in men with type 2 diabetes.
Materials and Methods: In this quasi-experimental study, 20 men with type 2 diabetes were randomly divided into two groups: low-volume high-intensity interval training (n=10, age= 50.70±4.27, height = 1.72±0.06, weight = 82.21±7.07, body mass index = 27.81±2.19) and control (n=10, age = 48.10±5.30, height=1.70±0.07, weight =80.56±6.16, body mass index = 28.13±4.13). Subjects in the experimental groups performed low-volume high-intensity interval training for three sessions per week for eight weeks. The subjects trained in two four-minute intervals (2 x 4 minutes) in the first to fourth weeks, and in three four-minute intervals (intensity 85 to 90% of maximum heart rate) in the fifth to eighth weeks, with three minutes of active recovery (intensity 65 to 75% of maximum heart rate). The total duration of the training session was 21 to 28 minutes. Before and after the intervention, blood samples were taken from the subjects. The concentrations of subfatin and interleukin-4 were measured using ELISA kits specific for human samples. The Shapiro-Wilk test was used to examine the normality of the data, and the Levene test was used to examine the homogeneity of variances. To examine and compare the differences between groups after the intervention, the analysis of covariance test was used, and to examine the differences and changes within groups, the paired t-test was used. The analyses were performed at a significance level of P<0.05, and SPSS version 16 software was used to analyze the data.
Results: The results showed that after eight weeks, body weight (post-test mean =81.49±6.92, pre-test mean=82.21±7.07, effect size=0.258, p=0.026), body mass index (post-test mean=27.57±29, pre-test mean =27.81±2.19, effect size=0.271, p=0.022), body fat mass (post-test mean =22.22±97, pre-test mean=3.09±56, effect size= 0.214, p=0.046), fasting glucose (post-test mean =119.60±12.85, pre-test mean=134.80±11.16, effect size =0.366, p=0.006) and subfatin (post-test mean=3.26±38, test, mean pre-test=2.68±1.56, effect size=0.475, p=0.001) was significantly reduced in the low-volume high-intensity interval training group compared to the control group. However, no significant change was observed in interleukin-4 between the two groups (mean post-test =8.04±4.38, mean pre-test =7.19±2.70, effect size =0.080, p=0.241).
Conclusion: The results of the present study suggest that low-intensity interval training with sparing training time may be effective in reducing weight and body fat mass, fasting glucose, and improving subfatin levels in patients with type 2 diabetes. However, this type of training had no effect on interleukin-4 levels.
