Therefore, the objective of this study was to &nbsp;assess the effect of beetroot juice intake on lipid profile in female soccer players.<br> <strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Methods: </strong>Young and well-trained female soccer players (N=20) were&nbsp; included in a randomized placebo-controlled crossover study. They were categorized into two groups: experimental (beetroot beverage, n=10, age: 23.20&plusmn;0.91 years, BMI: 22.57&plusmn;1.54(kg/m²)) and control (placebo, n=10, age: 23&plusmn;0.81 years, BMI: 23.13&plusmn;0.58(kg/m²)). Subjects drank either 200 ml concentrated beetroot beverage or an equal amount of placebo 2 hours prior to their trainings for six weeks (18 session). Blood samples were taken 24 hours before and after trials. All data were compared in pretest and posttest&nbsp; via paired sample t-test and independent sample t-test. All statistical analyses were performed at (P&le;0.05) by SPSS (version22).<br> <strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Results: </strong>Beetroot juice intake increased plasma high density lipoprotein (t= -60.88, P<0.05). Triglyceride, total cholesterol, and low density lipoprotein were&nbsp; reduced (P<0.05). Compared with placebo, beetroot&nbsp; juice reduced the concentrations of triglyceride, total cholesterol, and low density lipoprotein (P<0.05).<br> <strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Conclusion: </strong>Regular beetroot juice intake has significant effects on lipid profile in female soccer players, hence its suggestion for preventing diseases such as&nbsp; hypercholesterolemia and&nbsp; hypertension in female soccer players.<br> <strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Key words:</strong> Soccer, Training, Dietary Supplements, Lipids.</div> Soccer, Training, Dietary Supplements, Lipids 26 30 http://mlj.goums.ac.ir/browse.php?a_code=A-10-842-1&slc_lang=en&sid=1 maryam lotfi m.lotfi7344@gmail.com 100319475328460021554 100319475328460021554 No Department of Exercise Physiology, Faculty of Sport Sciences, Razi University, Kermanshah, Iran mohammad azizi azizimihammad@gmail.com 100319475328460021555 100319475328460021555 Yes Department of Exercise Physiology, Faculty of Sport Sciences, Razi University, Kermanshah, Iran worya tahmasebi worya2626@gmail.com 100319475328460021556 100319475328460021556 No Department of Exercise Physiology, Faculty of Sport Sciences, Razi University, Kermanshah, Iran parviz bashiri bashiri@gmail.com 100319475328460021557 100319475328460021557 No Department of Animal Science, Faculty of Agriculture and Natural Resources, Razi University, Kermanshah, Iran
