Sleep low

Details and patient eligibility

About

The investigators will examine the long-term effects of a combined training and diet intervention that, acutely, increases fat oxidation during exercise. This is done with a 4 week intervention study with moderately trained cyclists. Performance is tested pre and post intervention and muscle biopsies are obtained.

Sex: Male

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers

20 participants in 2 patient groups

Low group

Experimental group

Description:

This subjects in this group conducts all their morning exercise sessions with high fat oxidation (in a fasted condition). Thus, the subjects in this group after high intensity exercise in the evening do not get any carbohydrates to eat after training until the exercise session the following morning has been conducted.

Treatment:

Other: Combined exercise and diet intervention

High group

Active Comparator group

Description:

This subjects in this group conducts all their morning exercise sessions with low fat oxidation (in a fed condition). Thus, the subjects in this group after high intensity exercise in the evening do get carbohydrates to eat after training until the exercise session the following morning has been conducted.

Treatment:

Other: Combined exercise and diet intervention
