Production of free radicals is a natural process during various
metabolic events. The process may be altered due to various internal
and external factors. Increased antioxidant capacity is one of the
responses of human body against attack of free radicals. Many factors
may affect the antioxidant capacity with various potential values in
health and disease. The aim of this study was assessment of antioxidant
potential in plasma after aerobic exercise, consumption of green tea
and combination of both. Material and Method. Three
groups of 35 healthy women (mean age 30.1▒1.5 years) entered the study.
The first group was composed of those attending an aerobic training
course, the second group agreed to drink 3 mugs of green tea a day and
the last group agreed to do both tests. Their blood samples were collected
three times during the study, i.e. beginning, after two weeks and at
Results. A significant increase
in catalase activity and uric acid concentration together with
decreased concentration of malondialdehyde was observed.
Enhanced activity of antioxidants in plasma is the beneficial effect of
aerobic exercise, green tea and, most interesting, synergism of both.
Since production of malondialdehyde is marker of cell damage, its
reduced concentration after the period of treatment is indicative of
increased natural resistance of the body to free radical attack.
