Muscle can secrete healthy cytokines. Muscles can help us with our daily activities. In addition, during physical activity or exercise training, muscles can secrete healthy muscle cytokines. Muscle cytokines have two functions:
It can inhibit the hypertrophy of adipose tissue, and then reduce the pro-inflammatory cytokines (adipocytokines) secreted by fat. It can reduce the incidence of diabetes, cardiovascular diseases, cancer, osteoporosis and other diseases (see figure 1). These data were published in the journal Nature Review-Endocrinology (2012; 8:457-465)。
By strengthening muscles and promoting the secretion of muscle cytokines through exercise, the harmful effects of adipocytokines on health can be offset. Therefore, muscle cytokines can directly or indirectly reduce the occurrence of many diseases (diabetes, cardiovascular diseases, cancer, osteoporosis, etc.). ).

The reduction of short-term physical activity significantly affects health indicators. Even short-term physical inactivity can cause metabolic changes, including: decreased insulin sensitivity (easy to induce diabetes), decreased postprandial lipid metabolism (leading to hyperlipidemia), decreased muscle mass, visceral fat accumulation and so on.
The joint research team of the University of Copenhagen in Denmark and the University of Missouri at Columbia in the United States reduced the daily activity of 10 healthy young volunteers from the average daily 10 and 50 1 step to the average daily 1.344 step for two weeks. Before and after the intervention, the maximum oxygen consumption of blood was tested.
The results showed that only two weeks of walking activities decreased, which significantly reduced the insulin sensitivity of peripheral cells, cardiovascular health and leg muscle mass. These research results were published in Journal of Applied Physiology (2010; 108: 1034- 1040)。 (Recommended reading: Exercise every day 15 minutes, you can live for 3 more years. )
The health function of muscle must be stimulated by exercise or activity?

It can be inferred from the above research that in order to play the role of muscle in promoting health, it is necessary to carry out physical activity regularly or exercise regularly every day to secrete muscle cytokines, so as to maintain health and reduce diseases.
Even a small amount of activity is good for your health. It is suggested that when watching TV at work or leisure, you should get up and exercise for 5 minutes every 30 minutes, such as walking, lifting your legs, shaking hands, turning around and bending over. Never "sit back and wait".
