## 1 Introduction  
Athletes often turn to micronutrient supplements to improve their performance, improve immune function, or correct mineral and vitamin deficiencies [1]. In addition, athletes consume antioxidant-containing foods to minimize oxidative stress that may occur due to exercise as well as to increase their performance [2]. One of the important antioxidant sources that can reduce the harmful effects of oxidative stress is fruits and vegetables [3]. Fruits and vegetables have a very rich content of vitamins, minerals, fiber and antioxidants [4]. It has been stated that pomegranate (_Punica grantum_ L.) fruit, which has many healing properties for health, prevents or helps treat various disease risk markers (such as oxidative stress, hyperglycemia, high cholesterol and inflammatory activities) [5]. It has been reported that regular consumption of pomegranate juice or pomegranate juice concentrate (PJC) is associated with a decrease in blood pressure, improvement in blood lipid levels and reduction in oxidative stress [6; 7]. [PERSON] et al. (2016) reported that pomegranate juice supplementation had a positive effect on the modulation of fat and protein damage in endurance-based athletes [8]. The reason for this healing feature of pomegranate is due to the various phytochemicals it contains, which are responsible for its strong antioxidant and anti-inflammatory potential [9]. It is emphasized that black carrot (_Dacus carota_ L.), which has another antioxidant property and is a source of polyphenols, including phenolic acids, has significant effects on improving health [10]. These, like pomegranate, increase antioxidant activity [11] and also lead to improvements in lipid peroxidation and cardiovascular risk markers [12]. Additionally, a recent study reported that the combined application of pomegranate-black carrot juice with exercise reduced the level of oxidative stress [13]. It is stated that exercise causes an increase in oxidative enzymes and microinjuries in skeletal muscle [14]. Additionally, some studies have reported that Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) enzymes increase, depending on the type and intensity of exercise [15; 16; 17]. However, there is no clear consensus in the literature as to which form of exercise can change these parameters and to what extent. One of the macronutrients that is important for the human body is lipids [18]. Since the lipid profile changes depending on physical activity, it is very important to understand the working mechanism of lipid metabolism for both athletes and sedentary individuals [19]. In a study conducted by [PERSON] et al., it was reported that exercise and diet application can regulate one's lipid profile, ghrelin, and leptin levels, and increased irisin with exercise can activate lipid metabolism and support positive changes in lean mass [20]. Fatty acids (FAs) are also an important energy source during exercise [21; 22; 23]. FAs are considered a basic component of the erythrocyte membrane. In addition, exercise and nutrition are two factors that affect their structure and function [24]. In a study conducted by [PERSON] et al., it was reported that physical activity application combined with a standard diet program caused a significant decrease in linoleic acid (C18:2) and omega-6 PUFAs and an increase in stearic acid (C18:0) and oleic acid (C18:1) concentrations [25]. FAs are an important energy source for skeletal muscle contraction, especially during light-moderate intensity and long-term exercise [26]. It has been stated that FAs and lipid intermediates derived from them may play a role in the regulation of skeletal muscle mass and function [27]. Consuming antioxidant-containing foods can reduce exercise-induced muscle damage and oxidative stress markers. For this reason, the hypothesis that the beneficial effects of pomegranate-black carrot juice, known for its rich antioxidant content, may have positive effects on mineral metabolism, fatty acids and some biochemical parameters was tested in this study.
