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

Document Type : original article


Purpose: The purpose of this study was to investigate the response of cortisol levels, TNF-α and plasma lactate to acute Q10 supplementation during constant load exercise in active females. Methods: 24 subjects were randomly assigned to supplementation and placebo groups. Supplement containing 2 mg per kg of body weight, 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 test blood samples were collected. Data were analysed using the t test. Results: The results showed no significant differences 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 lactate and immune system, it seems that there is no need for the use of this supplement in active people.
