Any exercise before the physical examination will affect the test results. Many tests are carried out by detecting the chemical composition of blood or body fluids. Exercise is a muscle contraction activity regulated by the nervous system. During this period, blood circulation, respiration, kidneys, etc. It will be regulated by function, which will lead to changes in cell metabolism, which will lead to changes in the chemical composition of blood and body fluids, and then affect the test results.
It should be reminded that even a slight activity will lead to an increase in physiological blood sugar and a change in endocrine hormone levels, while strenuous muscle activity will obviously affect metabolism in the body. For example, the peak value of creatine kinase that caused Xiao Zhang to be misdiagnosed, 1 1 hour later can reach 1 times before exercise, and it will be 60 hours before it can return to its original level.
Don't do strenuous exercise two days before physical examination.
The amount of exercise has different effects on laboratory projects. Static motion has little influence, while dynamic motion has great influence. In particular, strenuous exercise such as long-distance running, swimming and football matches will cause drastic changes in some chemical components in blood and body fluids, such as the increase of white blood cells in blood and the increase of urine protein and uric acid, which will lead to misdiagnosis.
