A new study in the United States says that lifting an hour a week can reduce the risk of heart disease and stroke.
By analyzing the exercise data of 13,000 adults, Iowa State University researchers found that weightlifting can reduce the prevalence of metabolic syndrome. Metabolic syndrome is a general term for symptoms such as hypertension, hyperglycemia, and dyslipidemia, which may lead to coronary heart disease, stroke, and diabetes. Data analysis showed that weekly exercise exercises such as weightlifting for less than an hour reduced the risk of metabolic syndrome by 29%, the risk of hypercholesterolemia by 32%, and the risk of heart attack and stroke by 40% to 70%.
Researchers say that the body's muscles are a powerful device that burns heat, helping joints and bones to work, and also promoting metabolism. If you have a muscle, even if you do not have aerobic exercise, you can burn more calories, effectively prevent obesity, and have far-reaching benefits for your health. Li Dejun, an academic researcher and associate professor of athletics at Iowa State University, said: "People may think that resistance movements are not as easy to implement as aerobic exercise. In fact, only two sets of barbells are needed, less than five minutes. On the back of the press, you can have an effect.†Professor Li added: “The new study says that 'weightlifting' does not require us to go to the gym to practice, squatting in heavy shopping or digging holes in the yard. Because it is the key to strengthening muscle strength by lifting heavy objects."

The automatic enzyme immunoassay analyzer is based on the principle that the enzyme and the substrate can produce a color reaction, the absorption lines of different substances have different characteristics, and strictly abide by the Lambert-Beer law, quantitative and qualitative analysis of substances. instrument. The method of analyzing the content of various enzymes such as antigen or antibody generally mainly adopts colorimetric method. In practice, spectrophotometry is the basic working principle of an automatic enzyme immunoassay analyzer. The light emitted by the light source lamp becomes a beam of monochromatic light after passing through a filter or a monochromator. The monochromatic light beam passes through the sample to be tested in the microtiter plate, and part of the monochromatic light beam is absorbed by the sample and reaches the photodetector. The intensity of the light signal projected on it is converted into the magnitude of the electrical signal by the photodetector. This electrical signal is processed by pre-amplification, logarithmic amplification, analog-to-digital conversion, etc., and then sent to the microprocessor for data processing and calculation, and the test results are output by the display and printer. The microprocessor completes the movement in the X and Y directions of the mechanical drive through the control circuit.
The automatic enzyme immunoassay analyzer adds the sample to the microwells of the pre-coated antigen or antibody microtiter plate, washes after the reaction, removes the unseparated ligand, then adds the enzyme isolate, after incubation, washes again , remove the unseparated compound, and then add the enzyme substrate, after the reaction, the colored final product is formed, and the stop solution is added to stop the reaction. The absorbance of each microwell of the microtiter plate is read by the wavelength that has been set by the spectrophotometer. The concentration value of the analyte in the sample is calculated by the absorbance value of the sample and the standard curve, so that the quantitative result can be obtained, or the absorbance of the sample is compared with that of the standard product, so that the positive or negative qualitative result can be obtained.
