Abstract Introduction: Intense and exhausting exercise causes excessive production of free radicals and inflammatory markers, resulting in decreased athletic performance. Some studies have suggested that young and active people who engage in strenuous physical activity use antioxidant supplements to reduce the levels of inflammatory markers, muscle damage, and oxidative stress, as well as to increase endurance and strength performance indexes. Tartrate or tartaric acid as a flavonoid with antioxidant and anti-inflammatory properties is one of the antioxidant supplements that can prevent the development of free radicals as well as inflammatory markers such as interleukin-6 (IL-6). Therefore, the aim of this study was to evaluate the effect of short-term supplementation of tartaric acid for one week on inflammatory, oxidative stress and functional indices of active young men.Methodology:In this quasi-experimental study, 19 young active men with an age range (20-25 years, at least one to two years of training experience and maximum oxygen consumption between 45-55 ml per kg of body weight per minute) were selected and in two Intensive interval training (HIIT) group with and without short-term tartaric acid supplementation. Intense interval training was performed for a week and a total of 6 sessions. Each training program included 10 minutes of warm-up (with a variety of stretching, flexibility, walking and running) and 14-22 minutes of main activity, which in both groups. It consisted of 3 periods with 4 repetitions and 15-30 seconds of running with an intensity of 95-85% of the reserve heart rate (pressure perception 16 to 19) in each repetition, with 30-60 seconds of active rest after each repetition and 3 after each period. They had minutes of active rest (active rest in the range of 40-50% of the stored heart rate). In one week of activity, in order to maximize the inflammatory and oxidative stress indices, the principle of overload was observed from the first day to the last day of sports activity. Tartaric acid supplementation of 20 mg / kg body weight per day in capsule form with 150 ml of mineral water for one week. Finally, blood samples were taken 24 hours before the first and 24 hours after the last exercise performance test (baseline conditions, 10 minutes after exercise performance, 24 hours after exercise performance) in six stages. The obtained data were evaluated using 2 * 6 variance analysis test at a significance level of 0.05 using SPSS software version 24. Results: The results showed that hight intense interval training with and without supplementation in individuals for one week, significant changes in interleukin 6, malondialdehyde, total antioxidant capacity and also in anaerobic power performance (Rast test) ( p≤0.005) but at the levels of lactate, creatine kinase and lactate dehydrogenase these changes (p≥0.05) were not significant.Conclusion: According to the results, it seems that short-term consumption of tartaric acid probably improves the total antioxidant capacity and anaerobic power, as well as reducing inflammation and oxidative stress caused by exercise. These effects may be due to the polyphenol compounds in tartaric acid and its antioxidant properties.
