Background of the study:
Astaxanthin has been shown to be a powerfull anti-oxidant. Health benefits have been shown in animals and humans. Exercise enhancing effects have been shown in animals via enhancement of fat oxidation. We want to examine the effects of 4 weeks of astaxanthin supplementation on fat oxidation and cycling performance in trained cyclists
Objective of the study:
To test the hypothesis that 4 weeks supplementation with astaxanthin will improve fat oxidation and improve exercise performance in trained cyclists
Double blind, placebo controlled study.
Well trained cyclists between 18-30 years old
Intervention (if applicable):
astaxanthin (20 mg/day) or placebo for 4 weeks
Primary study parameters/outcome of the study:
performance on a time trial after 90 min steady state exercise.
Secundary study parameters/outcome of the study (if applicable):
substrate use plasma glucose plasma lactate plasma free fatty acid plasma astaxanthin
Nature and extent of the burden and risks associated with participation, benefit and group relatedness (if applicable):
The risks involved in participating in this experiment are minimal. Astaxanthin has been shown to be safe. Insertion of the catheters in a vein is comparable to a normal blood draw and the only risk is of a small local haematoma.
