The purpose of the study was to compare the effect of either moderate or high intensity aerobic exercise on inflammasome, M1, M2 macrophage infiltration and brown adipocyte markers in subcutaneous adipose tissue of the high fat diet-induced obese mice. The 4 weeks male C57BL/6 mice were randomly assigned to four groups: normal diet control (NC; n=10), high-fat diet control (HC; n=10), high fat diet with moderate intensity exercise (HME; n=10), or high fat diet with high intensity exercise (HIE; n=10) groups. The high fat diet was given 60% calories from fat whereas normal diet was given 18% calories from fat. The moderate intensity exercise group (HME) was set at 10m/min in the first 2 weeks, 12m/min in 3-5 weeks and 14m/min in 6-16 weeks and the high intensity exercise group (HIE) was set at 14m/min in the first 2 weeks, 17m/min in 3-5 weeks and 18m/min in 6-16 weeks. The semi quantitative reverse transcription-polymerase chain reaction (RT PCR) was used to analyze the gene expression. The moderate intensity exercise significantly reduced the expression of NLRP3, F480, CD11c and CD86. Further, the moderate intensity exercise significantly increased CD206 and PGC1α, BMP7 and PRDM. The high intensity exercise significantly reduced NLRP3, CD11c and CD86. Further, the high intensity exercise significantly increased PGC1α and BMP7. In conclusion, moderate intensity exercise has more positive effects on inflammasome, M1, M2 macrophage infiltration and brown adipocyte maskers compared to high intensity exercise in high fat diet induced obese mice.
