Comparison of the percentage of energy from each macronutrient category. The percentages were calculated by dividing the available energy from the macronutrients by the total energy. a The percentage of the energy obtained from carbohydrates; b The percentage of the energy obtained from protein; c The percentage of the energy obtained from total fat. The red line represents acceptable macronutrient distribution ranges (AMDR). The AMDR for carbohydrates is 55 to 65%, for total fat is 15 to 30%, and for protein is 7 to 20% of the energy intake for Korean adults. Controls versus bodybuilders: ⁺p < 0.05 or ⁺⁺⁺p < 0.001, bodybuilders versus distance runners: ^**p < 0.01 or ^***p < 0.001
