Abstract:
Older and younger men completed 12 weeks of resistance training and ingested either 500 mL of chocolate milk or placebo daily. Training increased strength in both age groups (p < 0.05), with no supplementation effect. Type I muscle fibre area increased with training (p = 0.008) with no effect of age or supplementation. Type II fibre area increased (p = 0.014) in young men only with no supplementation effect. Chocolate milk did not enhance skeletal muscle hypertrophy following training.
