Abstract

Cyclists rode 13% longer using carbohydrate-protein gels compared to carbohydrate-only gels.

  • Endurance performance improved significantly with carbohydrate-protein gels, with a mean duration of 116.6 minutes compared to 102.8 minutes with carbohydrate-only gels.
  • Both male and female participants showed similar endurance responses to carbohydrate-protein and carbohydrate-only gels, indicating no significant difference based on gender.
  • Post-exercise muscle damage, as measured by creatine kinase levels, was not significantly different between the two gel treatments.
  • Creatine kinase levels increased after exercise in the carbohydrate-only trial but did not significantly rise in the carbohydrate-protein trial.
