Abstract
Exercise training and rice bran have anti-inflammatory effects. However, the effect of combining the two interventions on inflammatory factors is unclear. Therefore, the present study aimed to investigate the effect of aerobic training and rice bran consumption on the levels of selected inflammatory factors in overweight men. Sixty overweight men were randomly divided into four groups (n=15): control, rice bran, progressive aerobic training, and training + rice bran. Progressive aerobic training was performed at an intensity of 60-75% of maximum heart rate for, 20-35 min, 8 weeks, with 3 sessions per week. Rice bran was consumed in an amount of 10 grams twice a day (before breakfast and before sleeping). Before and after the completion of the interventions, blood samples were taken and serum levels of CRP, IL-6, and TNF-α were measured by ELISA. Analysis of covariance with Bonferroni post hoc test was used to interpret the data. There were significant decreases in the levels of CRP, IL-6, and TNF-α with training and training + rice bran compared to the control and rice bran groups (p<0.05). The CRP and TNF-α reduction was also significant after rice bran consumption compared to the control group (p<0.001). Moreover, decrease in the levels of IL-6 (p=0.002) and TNF-α (p<0.001) in the training +rice bran group compared to the training group was also significant. The findings confirmed that aerobic training and rice bran consumption are effective in reducing inflammation, and there was a synergistic effect of rice bran supplementation and aerobic training.

Abstract
Introduction
High-Intensity exercise is accompanied by inflammation and oxidative stress. This study aimed to investigate the effect of the FIFA test with curcumin supplementation on serum MDA, TAC, and CRP in male football assistant referees.
Method
In this semi-experimental study, 20 football assistant referees (mean age 28.56±3.75 years, height 179±4.21 cm, weight 72.78±7.08 kg) were selected voluntarily then were randomly assigned to the curcumin + FIFA test and the FIFA test groups. The test + supplement group, in addition to FIFA tests, received 5 grams of curcumin daily (2.5gram at morning and 2.5 gram at evening) for five days. Blood sampling was performed in three stages (before supplementation, two and a half day before, immediately after, and 48 hours after the FIFA Interval Physical Fitness Test) and serum levels of variables were measured using the spectrophotometric method. Repeated-measures ANOVA and Bonferoni post hoc tests were performed in SPSS26.
Results
There was significant increase in serum CRP, MDA, and TCA in both groups in the first post-test (P=0.000, P=0.041, P=0.008, P=0.009, P= 0.048, P=0.014). Also, in the second post-test of the test group, the increase in CRP and MDA levels remained significant (P = 0.000, P = 0.022). However, TAC became a non-significant increase (P=0.160), while its increase in the test + supplement group was still significant (P=0.013), and in the test + supplement group, MDA became a non-significant increase compared to the pre-test (P=0.186), while in the test group it still had a significant increase (P=0.022). In addition, there was a significant difference between the groups in CRP and TAC values (P=0.024, P=0.05) and a non-significant difference in MDA levels (P=0.129).
Conclusion
Curcumin modulates some of the inflammatory and oxidative stress indices induced by endurance exercise (the FIFA test).
