Abstract
Background: Adiponectin is one of the most well-known adipokines with anti-inflammatory effects that plays an important role in regulating the whole-body metabolism. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) versus moderate intensity continuous training (MICT) on the circulating levels of adiponectin in individuals with and without metabolic disorders.
Methods: A systematic search was conducted in the databases of PubMed, Web of Science, Academic Jihad Center and Magiran using the keywords "HIIT" and "adiponectin" to identify Persian and English languages published articles until October 2022. Effect size (SMD) and 95% confidence interval were calculated using CMA2 software. I2 test for calculation of the heterogeneity and visual interpretation of funnel plot test and Egger test for assessment of the publication bias were used.
Results: Data analysis of 28 interventions (24 studies) showed that HIIT resulted in a significant increase in adiponectin [0.40 CI: 0.12 to 0.68), P=0.004]. Also, the data analysis of eight interventions showed that HIIT led to a non-significant increase in adiponectin compared to the MICT [0.41 CI: -0.04 to 0.86), P=0.07].
Conclusions: The findings of the present study showed that HIIT is a suitable and efficient training method to increase adiponectin, especially in people with metabolic disorders.

Abstract
Background: Interval exercises with high intensity and consumption of plant extracts probably have beneficial effects on inflammatory indicators. The aim of this study was to investigate the effect of eight weeks of High-Intensity Interval Training (HIIT) and the consumption of Loquat leaf extract on the serum levels of TNF-α and interleukin-18 in obese men with non-alcoholic fatty liver disease.
Methods: In this semi-experimental study, forty men with non-alcoholic fatty liver disease with body mass index (33.92 ± 1.82) with informed written consent were randomly selected and assigned into four groups: control, training, Extract, Extract + training (Each group of 10 people). Exercises were performed for eight weeks and three sessions per week for 60 minutes with intensity between 80-95% of the reserve heart rate. Two capsules of 250 mg of Loquat leaf extract were also prescribed daily. Paired t-test and analysis of covariance were used.
Results: A significant decrease in the levels of TNF-α (15.3%) and interleukin 18 (14.9%) was observed in the training + extract group (P<0.05). A significant difference was observed in the levels of TNF-α (P=0.001) and interlock 18 (P=0.001) between the groups, and these changes were more significant in the Extract + training group than in the training and extract groups.
Conclusions: It is concluded that performing intense intermittent training along with Loquat leaf extract will be able to improve TNF-α and interleukin 18 indices related to fatty liver in people with non-alcoholic fatty liver disease. However, confirmation of this hypothesis requires more research.
