Compare a dietary supplement (PRJ-205) and placebo during 1 or 4 days on aerobic exercise performance, oxidative stress and muscle damage.
The hypothesis is that supplementation with PRJ-205 improve aerobic performance
Twenty young active males will be recruited and randomized to either placebo or PRJ-205. Subjects will take the designated treatment in an acute dosage and chronically, 4 days of treatment.
They will undergo 3 exercise tasks (before the administration of the product, 1.5h after the acute administration of the product and after 4 days of treatment). VO2max and anaerobic threshold will be measured during the tests. Blood samples will be taken to measure muscle damage and oxidative stress.
