The Effect of 8 Weeks of High Intensity Interval Training (HIIT) and Green Tea Consumption on Serum Levels of Thioredoxin Reductase-1, Paraoxonase-1, Interleukin-1β, Interleukin-6 and Galanin in Obese Elderly Untrained Men

Nowadays, the appropriate exercise pattern along with the consumption of medicinal plants plays an important role in regulating energy balance, reducing inflammatory indicators and increasing antioxidant defense in obese elderly people.Therefore, the aim of this study was to investigate the effect of 8 weeks of HIIT and consumption of green tea on serum levels of antioxidant enzymes, inflammatory markers and galanin in obese elderly untrained men.

Methods & Materials:

In this study, 48 obese elderly untrained men were randomly divided into four groups including: HIIT, HIIT with Green Tea, Green Tea and Control. HIIT were performed for 8 weeks (3 sessions per week) with 90% HRR. 450 mg of green tea was received daily (six capsules per day).Blood samples were taken before and 48 hours after the last training session. Statistical analysis was performed using Shapiro-Wilk test and two-way analysis of covariance.Data were analyzed using SPSS-26 software with a significance level of p<0.05.

The results showed that the combined effect of HIIT with green tea consumption and the main effect of HIIT alone caused a significant increase in the levels of thioredoxin reductase-1, paraoxonase-1 and a significant decrease in the levels of interleukin-1β, interleukin-6 and galanin(P<0.05).But consumption of green tea alone did not show significant changes(P>0.05). The highest percentage of changes (increase and decrease)created in biochemical variables was attributed to the HIIT with green tea group.

Performing HIIT with green tea consumption had the greatest effect on reducing inflammatory markers, increasing antioxidant enzymes and energy balance in obese elderly untrained men.
