Anthropometric status and macronutrient intake of bodybuilding athletes in Limpopo province, South Africa

Abstract

Bodybuilders in Limpopo Province adhere to various training and dietary routines to attain their desired physique. However, the anthropometric status and macronutrient intake of these athletes remain unknown. A total of ninety-three bodybuilders from the Capricorn District, Limpopo Province, who were members of IFBBSA, participated in the study. Ethics approval was granted by the University of the Free State Health Science. Athletes signed informed consent before participation Measurements of weight and height were taken to calculate body mass index (BMI), waist circumference (WC), mid-upper arm circumference (MUAC), and body fat percentage (BF%). Three 24-hour-recall questionnaires were completed. The SAMRC FoodFinder-3 was used to analyse macronutrients, with the mean values considered. Data were exported to the SPSS (v28), and descriptive statistics were applied. Pearson’s correlation test was used to determine the relationship between variables. The BMI was 25.8±4.4 kg/m2 in males and 24.9±3.6 kg/m2 in females, while MUAC was 35.6 cm for males and 28.3 cm for females. About half of both genders exhibited excess BF% (9.9% for males and 17.3% for females). Most males (81.6%) and all females had acceptable WC. Energy intake was 148 kJ/kg/day and 142 kJ/kg/day while carbohydrate intake was 4.7 g/kg/day for males and 4.3 g/kg/day for females. Fat intake was high in both genders. However, protein intake was optimal in males (1.4 g/kg/day) and suboptimal in females (1.1 g/kg/day). About half of the bodybuilders exceeded the sport-specific recommendations for BF%. However, the energy and carbohydrate intakes were suboptimal, while protein and fat intakes were optimal and high respectively.
