Antioxidant Function of Vitamin A, C and E-Vitamin

 Activities of antioxidant vitamins are interested, some athletes, especially due to the use of the increased production of reactive oxygen species (ROS) associated with muscle fatigue and muscle damage. In addition, neutrophils and macrophages produce ROS macros. ROS produced by the immune system relevant to be able to adapt to the post-exercise muscle damage.

A reason other than the vitamins C and E may be of interest to athletes and their potential immunostimulating property. Antioxidant vitamins may have different immunomodulatory effects.


reactive oxygen species (ROS) are formed in intense physical activity, which causes oxidative stress and associated reduction of antioxidants, muscle damage and fatigue. High antioxidant protection against free radicals. One hypothesis is that a large addition of vitamins C, E and beta-carotene may protect against exercise-induced oxidative stress and many studies have examined this possibility. Vitamin E (alpha-tocopherol) is considered the most important treasure of the ROS membranes and is probably the study of the exercises.

Several studies have shown that there are education and training related to the reduction of the accumulation of the products used to assess oxidative stress or to increase antioxidant enzymes. Some studies suggest that vitamin E protected against oxidation by exercise. However, the results of animal and human studies, that vitamin E supplement does not improve the performance and the muscles can reduce damage after a marathon.

Understanding the interaction between the immune system to the production of ROS and damage to the muscles provide information on antioxidants and exercise-induced muscle damage. Although these interactions are not known, it seems that the production of ROS by cells of the immune system can be an important factor in the recovery of muscles after training be. Neutrophils and macrophages seem to penetrate into areas of muscle damage after exercise and two of these cell types ROS production. The release of ROS can increase the release of cytokines and cytokine production of ROS can lead to the release of cytokines and ROS are important, you can help remove the damaged tissue and muscle repair. Recent studies show that ROS production can after the training useful in the correction. In this study, mice were higher when used in oxidative stress, prevents neutrophil function than mice, but 4 days after the symptoms of normal mouse muscle damage, except upon the facts and results from other studies that the production of free radicals and ROS during exercise may indicate an important part of the muscle tissue-based repair and play a high consumption of antioxidants may be beneficial.

Some researchers are to investigate and, if life can be extended by increasing intake of antioxidants. Evidence from two recent studies of dietary supplements rich in antioxidants do not add to the life and rodents fed a diet with more antioxidants the years of life in mice with the normal diet were infected. It seems that, although it may be associated with reduced production of ROS increased, life expectancy and the consumption of antioxidants in addition to any further increase in life expectancy.

Overall, the results of previous studies have shown that antioxidants do not improve the performance does not improve recovery of muscle use and benefit from the use of the increasing life expectancy of rodents.
