You’ve guessed it, yet another study expounding the great benefits of green tea.
So what was the study about and what did it show?
The study investigated the effects of the consumption of green tea for 7 days on biomarkers (i.e. indicators) of oxidative stress in young men undergoing resistance exercise.
Blood samples were taken before and after exercise and were analysed for total antioxidant capacity.
The control group (i.e. those who didn’t drink green tea) had reduced levels of Glutathione (a very strong antioxidant produced in the body). In addition other activities increased in the control group as a result of exercise (i.e. by-products: creatine kinase (CK), Aspartate aminotransferase (AST) & xanthine oxidase (XO)).
Green tea reduced the post-exercise concentration of some of the above by-products and increased the values of total polyphenols (antioxidants from Green Tea) and Glutathione. Green tea also inhibited a significant rise in the other by-products, namely CK and XO activities.
|Consumption of GT, a beverage rich in polyphenols, may offer protection against the oxidative damage caused by exercise, and dietary guidance for sports participants should be emphasized.|
