The effect of date seed powder supplementation on nutritional, oxidative, inflammatory and anti-inflammatory status and sport performance in runners

Abstract

t-test, independent Student’s t tests, analysis of covariance, and repeated-measures analysis of variance (ANOVA). Results: Based on the results of the analysis, supplementation with date seed powder for 2 weeks led to a significant increase in the TAC and a significant decrease in the levels of MDA, hs-CRP, IL 6, CK, LDH, and muscle pain (p<0.05) compared to the placebo group at the end of the intervention and 24 hours later. Also, the changes in anthropometric indices, body composition, food intake (before and after the intervention), SOD, and IL 10 (in three time periods (first, after the intervention, and 24 hours later) during the HIIT protocol were insignificant. Conclusion: Overall, the present study demonstrated that consumption of 26 g date seed powder compared to placebo for 2 weeks improves the inflammatory markers, antioxidant enzymes, muscle damage, and muscle pain, and as a result leads to an improvement in the athlete's sports performance. Thus, date seed powder can be introduced as a healthy and inexpensive antioxidant supplement for runners and athletes with high-intensity training.
