Abstract
Aim. Evaluation of diet and nutritional status in an elite group of professional race-walkers during the preparatory period.Basic procedures. The study was carried out in the spring of 2014 among 6 athletes who were the most advanced professional race walkers. Quantitative diet evaluation was based on diet monitoring with the use of the Wikt 2.0 programme. The level of implementation of the Swiss food pyramid for athletes was also assessed. Nutritional status was evaluated with the BIA method using the “Akern Srl” body analyser and “Bodygram” software.Main findings. The participants’ mean daily intake included: 2,912.35 kcal, 122.48 g protein, 392.80 g carbohydrates and 102.85 g fats. The mean consumption of lipophilic vitamins was: 1,351.29 μg (A), 3.80 μg (D) and 13.41 mg (E). The supply of hydrophilic vitamins was: 1.84 mg (B1), 2.04 mg (B2), 2.34 mg (B6), 4.14 μg (B12), 27.91 mg (B3), 315.56 μg (B9), 78.74 mg (C). The mean amounts of consumed macroelements were: 888.37 mg (Ca), 1,799.82 mg (P), 372.21 mg (Mg), 4,644.41 mg (Na) and 3,692.46 mg (K), and of microelements: 14.37 mg Fe, 14.46 mg Zn, 1.42 mg Cu and 178.34 μg J. Average daily consumptionof water and other sugar-free beverages was 3,090.93 L. Their body composition included: 65.78% of total body water, 10.12% of body fat, 88.88% of lean body mass and 51.93% of muscle mass. The mean BMI was 21.62 kg/m2.Conclusions. Both quantitative and qualitative mistakes were found in the diet of the elite group of professional race-walkers, such as: low supply of carbohydrates, some vitamins and mineral salts, as well as insufficient consumption of vegetables, fruit and dairy products.
