What the study found
Three inflammatory indices increased significantly within the carbohydrate-only group but not within the protein-carbohydrate group.
Participants and protocol
Twenty-five trained men completed ten weeks of endurance training with randomized, energy-matched recovery supplements. Researchers measured blood-cell counts and derived inflammatory indices.
What this cannot establish
Different within-group significance results do not by themselves establish a between-group effect. These biomarkers also do not demonstrate fewer infections, better race performance or an individual supplement requirement.
