Sweat with exercise not only aims to reduce weight but also has the ability to reduce the risk of breast cancer.
Scientists from the University of Minnesota in the United States, conducted a study with 391 subjects wearing inactive women, healthy, and in premenopausal condition were divided into 2 groups: control (no exercise) and intervention (exercise). They found that 179 women in the intervention group, who do 30 minutes of exercise 5 times a week for more than 16 weeks, showed changes in estrogen metabolism may explain the anti-cancer benefit derived from exercise.
"This study is the first study to show that aerobic exercise affects the breakdown of estrogen to produce good material to reduce the risk of breast cancer" said Prof. Mindy Kurzer, impersonating a professor of nutrition at the University of Minnesota.
The researchers measured three levels of estrogen that is E1, E2, E3 and materials other estrogen in the urine of subjects. At the end of the study, the control group (which exercise) had a body mass index (BMI) and better heart health, the group was also found to increase in the ratio of 2-OHE1 as much as 25% and a reduction of 16-alpha-jumalh OHE1, which is associated with a risk breast cancer. These changes were not found in the intervention group (no exercise).
Currently, the protocol that has been issued by the researchers recommend that you exercise for at least 150 minutes a week, which can be compared with a brisk walk for 30 minutes for 5 times a week. Although further study is needed on the effects of exercise in cancer risk reduction, regular exercise can promote health improvement.
