About

The purpose of this study is to determine whether glucose-fructose intake during training increases lactate transport and oxidation and improve endurance performance.

Full description

The study will enroll 24 healthy male volunteers. After baseline assessment of lactate transport and endurance performance, subjects will be randomized to either a 3-week intervention arm in which they will train with glucose-fructose intake during training, or to a control arm (water during training). After this 3-week intervention, lactate transport and endurance performance will be assessed again.
