Effect of resistance training and groups on endocrine markers. (A) IGF-1 (ng × mL⁻¹), (B) GH (pg × mL⁻¹), (C) testosterone (ng × mL⁻¹), (D) cortisol (ng × mL⁻¹), (E) myostatin (ng × mL⁻¹), (F) follistatin (ng × mL⁻¹), (G) follistatin–myostatin ratio. n = 15 per group, error bars represent standard deviation, open white circles indicate placebo group, closed black circles indicate high-protein diary milk ingestion group.
