Abstract

The time trial performance was faster with chocolate milk than with carbohydrate or placebo, with an average time of 79.43 minutes.

  • Muscle glycogen resynthesis was higher with chocolate milk and carbohydrate compared to placebo.
  • Phosphorylation of the mammalian target of rapamycin was significantly greater at recovery minute 45 with chocolate milk than with carbohydrate or placebo.
  • Phosphorylation of rpS6 was also higher with chocolate milk compared to placebo at recovery minutes 45 and at the end of recovery.
  • Phosphorylation levels of FOXO3A were greater at recovery minute 45 with chocolate milk and carbohydrate than with placebo.
