Response of cortisol TNF- α, and plasma lactate levels, to the coenzyme Q10 during exercise at a constant intensity in active females

Abstract

Purpose: The purpose of this study was to investigate the response of cortisol levels, TNF-α and plasmalactate to acute Q10 supplementation during constant load exercise in active females. Methods: 24 subjectswere randomly assigned to supplementation and placebo groups. Supplement containing 2 mg per kg of bodyweight, coenzyme Q10, which was dissolved in 250 ml water. Placebo also contained water with food colour.Supplement and placebo consumed 120 min before the exercise test. Before and immediately after the testblood samples were collected. Data were analysed using the t test. Results: The results showed no significantdifferences between the rest and after exercise in the value of cortisol levels, TNF-α and lactate (p>.05).Conclusion: According to the results of this study and not positive effects of this supplement on the lactateand immune system, it seems that there is no need for the use of this supplement in active people.
