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).

Abstract
The purpose of the present study was to investigate the effect of dual task training including balance sit-to-stand and cognitive exercises on postural control of sit to stand of elderly women with a history of falling. 15 elderly women were randomly divided into control (n=7) and experimental (n=8) groups. Participants implemented training protocol for four weeks in both experimental (balance and cognitive exercises) and control groups (balance sit-to-stand exercises). Before and after the training protocol, Berg Balance Scale and time of up and go tests were applied. Besides, in order to measure amplitude and speed of postural sway in the anteroposterior and medio-lateral direction in different stages of sit to stand movement in dual task condition, a force plate with a frequency of 100 Hz was used in pre-test and post-test. For data analysis, paired and independent t-test, nonparametric Wilcoxon and Mann Whitney u-tests were used with a significance level of P≤0.05. The results showed that there was a significant difference in the BERG test and significant reduction of the amplitude and speed of center of pressure in the antero-posterior and medio-lateral directions in the experimental group compared to the control group from pre-test to post-test (P≤0.05). Due to results, balance exercises by dual task method improved control functional balance and reduced postural sway and consequently improved sit to stand postural control in dual task condition and therefore can reduce more effectively the risk of falling in elder people.
