The authors of “Effects of Post-Exercise Whey Protein Consumption on Recovery Indices in Adolescent Swimmers” report an error in Table 1 of their article [1]. The somatic maturity estimation for the female swimmers was mistakenly based on the male equations. Thus, the somatic maturity of the female swimmers was re-calculated using the female-specific equation by Mirwald et al. [2]. The corrected table appears below. The corrected values do not change the results and scientific conclusions of the article.

Values are mean ± standard error; PHV = Peak Height Velocity, 24 h energy and macronutrient consumption including supplements. * Indicates significant difference (p < 0.016) between protein and carbohydrate and protein and placebo. Total supplement contribution was included for protein (+0.6 g/kg) and carbohydrate (+0.6 g/kg).
