Table 5: Energy intake of the athlete prior to the Olympic qualification. Dietary protein intake was prescribed to the athlete with the aim of optimizing protein synthesis and facilitating the recovery process from exercise while promoting the mitochondrial response to endurance and interval training sessions [2]. Therefore, the protein sources within the feeding plan of the athlete mainly consisted of foods with high-quality protein. Considering the protein intake provided to the athlete, the mean values for days with physical activity were 152.63 \(\pm\) 16.79 g per day for the days with only one training session planned and 158.28 \(\pm\) 3.49 g per day in the days with two swimming workouts. These values align with the recommended intake of 1.2-2 g/kg/day [2], underscoring the importance of increased protein intake in order to sustain the strength requirements of swimming. Due to the increased energy requirements of the athlete and the need to practically achieve an energy intake of at least 2910 \(\pm\) 379 kcal/day during rest days, the protein intake was greater (197.88 \(\pm\) 4.38 g/day) compared to days with scheduled training sessions. The approach was fundamentally supported by the need to reach the increased energy requirements of the athlete in order to prevent muscle catabolism and lean muscle mass loss associated with an unintentionally induced energy deficit due to the athlete's elevated energy demands [36]. Another reason why the protein intake during training days (152.63 \(\pm\) 16.79 g and 158.28 \(\pm\) 3.49 g, respectively) was lower compared with rest days (197.88 \(\pm\) 4.38 g/day) was attributed to protein's stronger impact on satiety levels compared to other macronutrients, facilitating a reduction in energy provision from food [11], which in the end could hinder the athlete's ability to obtain an optimal amount of energy from carbohydrates for physical activity [2]. Within the studied case, mean dietary fat intake (103.67 \(\pm\) 19.56 g/day) remained consistent across all activity levels.
