Most of the current sports nutrition products are still limited to the exercise itself, and less attention is paid to the protection of exercise-related cardiopulmonary and muscle organs. However, in recent years, there have been related research and new product development in this area. Among them, curcumin has become one of the most popular sports protection nutrients with its comprehensive functionality.
Exercise causes the body's demand for oxygen to rise rapidly, with the increase in respiratory intensity and speed, and thus the demand for the respiratory system increases. This is why the first thing that began to exercise and fitness is to enhance heart and lung function.
However, "the lungs are delicate", the pressure bearing capacity is very poor, it is easy to cause oxidative stress, induce inflammation and other lung health. Curcumin attracts the attention of researchers with its strong antioxidant capacity. In the article "Research Progress of Curcumin in Respiratory Diseases" published in the March 2014 issue of International Respiratory, Pang Qi et al. summarized the respiratory health functions of curcumin, including:
A, curcumin can inhibit the proliferation of fibroblasts by regulating the oxidation-antioxidation imbalance, and reduce the degree of pulmonary fibrosis;
B, curcumin can inhibit the carcinogenic effect of benzopyrene on mice by increasing the content of superoxide dismutase and catalase; curcumin can also inhibit the proliferation of cancer cells and induce apoptosis of lung cancer cells. Cancer cell proliferation;
C, curcumin can reduce the level of NO, reduce oxidative stress, inhibit airway inflammation, and exert anti-asthmatic effect;
D, anti-inflammatory and anti-oxidant properties of curcumin can reduce emphysema and airway inflammation caused by trypsin and smoke.
In short, the respiratory health problems caused by oxidative stress are more and more concerned by health workers. The anti-oxidation and anti-inflammatory effects of curcumin have been confirmed by many clinical studies, and its application in the field of respiratory health deserves in-depth study.
