Daily chocolate milk consumption does not enhance the effect of resistance training in young and old men: a randomized controlled trial

Appl Physiol Nutr Metab. 2015 Feb;40(2):199-202. doi: 10.1139/apnm-2014-0329. Epub 2014 Oct 16.


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.

Keywords: force; hypertrophie musculaire; muscle hypertrophy; strength; supplementation; supplémentation.
