The association between the intake of macronutrients and essential amino acids (EAAs) and muscle mass (in kg) as a dependent variable in the samples of anaerobic and aerobic male athletes (multivariate analyses). OR_adj—adjusted odds ratio (OR_adj = e^β); 95% CI—95% confidence interval; *—p-value < 0.05. ¹—reference category: muscle mass ≤ 61 kg; ¹—Nagelkerke R² = 0.59; the logistic regression model was adjusted for the age and training experience of anaerobic male athletes. ²—reference category: muscle mass ≤ 57; ²—Nagelkerke R² = 0.29; the logistic regression model was adjusted for the age and training experience of aerobic male athletes. BW—body weight; EI—energy intake; CHO—carbohydrates; PRO—protein; Leu—leucine; Iso—isoleucine; Val—valine; Phe + Tyr—phenylalanine plus tyrosine; Met—methionine; Lys—lysine; Try—tryptophan; Thr—threonine; His—histidine.
