Can I exercise and keep fit before the physical examination

It is generally not recommended to engage in vigorous exercise and fitness before a physical examination, but low-intensity activities are usually not affected. Exercise before physical examination may interfere with the accuracy of some examination results, especially blood tests and electrocardiograms. High intensity exercise should be avoided within 24 hours before the physical examination. Intense exercise may lead to a temporary increase in indicators such as creatine kinase and lactate dehydrogenase, which can affect the assessment of liver function, kidney function, and myocardial enzymes. The loss of water in the body after exercise may also lead to blood concentration, affecting blood routine and electrolyte test results. For projects that require fasting blood draws, post exercise blood glucose fluctuations may mask the true metabolic state. Some people may experience transient proteinuria after exercise, which can interfere with urine routine tests. Low intensity activities such as walking and yoga usually do not significantly affect the results 2 hours before the physical examination. This type of activity helps maintain a normal physiological state, but excessive sweating should be avoided. For projects that require blood pressure measurement, rest for at least 30 minutes after exercise. Special examinations such as exercise tablet tests require early cessation of daily exercise according to medical advice. Three days before the physical examination, one should maintain a regular routine and moderate activity to avoid sudden changes in exercise habits. Wear loose clothing for easy examination, and bring past medical examination reports for doctors' reference. On the day of the physical examination, a small amount of water can be consumed, but sugary drinks should be avoided. Long term fitness enthusiasts should inform their doctors of their exercise habits to help interpret the results. If you experience symptoms such as dizziness, stop exercising immediately and seek medical attention.
