Aging is a natural process coupled with oxidative stress and chronic inflammation, gradually associated with losing organ function over time. Therefore, the objective of the current work was to peruse the protective effects of 8-week moderate-intensity interval training (MIIT) and ginger extract supplementation on some biomarkers of oxidative stress, inflammation, and lipid metabolism in the liver of elderly males Wistar rats (animal study with ethical code IR.BMSU.REC.1401.015). A total of thirty-two 22-month-aged male Wistar rats were randomly assigned to four groups: (1) control, (2) MIIT, (3) ginger, and (4) MIIT + ginger. After 8 weeks of treadmill training and ginger extract supplementation, the biochemical parameters (liver enzyme and lipid profile), inflammatory mediators (leucine-rich α-2 glycoprotein 1 (LRG1), tumor necrosis factor-alpha, and interleukin-6), pro-oxidant (malondialdehyde), antioxidant biomarkers (catalase, superoxide dismutase, total antioxidant capacity), some lipid metabolism regulators (carnitine palmitoyltransferase 1, adipose triglyceride lipase, acetyl-CoA carboxylase, CD36, and AMP-activated protein kinase), and liver histopathological changes were appraised. The acquired findings pointed out that MIIT combined with ginger extract appreciably diminished the serum levels of LRG1, liver enzymes, and lipid profile relative to the other groups after 8 weeks of intervention. Furthermore, ginger + MIIT caused a great improvement in the liver levels of antioxidant biomarkers, pro-oxidant, pro-inflammatory biomarkers, lipid metabolism regulators, and liver tissue impairment compared to the other groups. The findings suggested that MIIT + ginger was more effective in improving examined indices relative to the other groups.
