Study Details

Study Description

Brief Summary

The purpose of this study is to investigate the effects of carbohydrate intake on training efficacy and health parameters of an endurance training program in healthy adults.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: Endurance Training
Early Phase 1

Detailed Description

Carbohydrate availability in endurance exercise seems to attenuate exercise-induced perturbations of cellular homeostasis and consequently diminishes the stimulus for training adaptation. Therefore, a negative relationship with exercise efficacy seems plausible. However, experimental evidence is rare and far from conclusive. Therefore, the present study aims to test the influence of carbohydrate intake on the efficacy of a typical preventive training program.
