Abstract
Background:In recent years, spirulina,a blue-green microalgae, has been widely used by athletes. It is believed that short and long-term consumption of spirulina can increase the activity of antioxidant enzymes such as SOD and lead to the reduction of lipid peroxidation and its side products such as MDA. This led to the use of spirulina as a method to improve recovery after sports activity. Immersion in cold water is another recovery method. It has been suggested that immersion in cold water (temperature below 15°C) can lead to an increase in the activity of antioxidant enzymes and a reduction in oxidative stress induced by exercise.
Aim:In present study, it is tried to evaluate the Synergistic effects of these recovery methods. Method:32untrained young men were voluntarily invited to participate. The participants were divided into four groups.(1)Control, (2)Cold water immersion, (3)Spirulina supplementation, (4)Spirulina+cold water immersion. The subjects performed 3 sets including eight weight resistance exercises with 80%1RM on the lower body muscles. Subjects of the cold water immersion group stood up to waist height in a small pool of 8°C water for five minutes. Blood samples were taken before and 15 minutes after the activity or immersion. MDA and SOD were analyzed through the ELISA test. First, all statistical assumptions(normality of the data distribution and the homogeneity of the variances) were evaluated. ANCOVA test was used to compare dependent variables between groups, and Bonferroni's post hoc test was used. For intra-group comparison of dependent variables correlated t-test was performed.
Result:The results indicated that all experimental groups significantly increased SOD and decreased MDA levels(P<0.05). However, there is no significant differences between three interventions in increasing SOD and reducing MDA levels(P>0.05).
Conclusion:According to the results, it can be concluded that spirulina supplementation,immersion in cold water and the intervention of these two together can lead to a significant increase and decrease of SOD and MDA levels. But there was no obvious superiority between these 3 interventions.
