Abstract：Establishing a reasonable lifestyle and physical exercise, taking effective health care and interventions are important for the general public to improve their quality of life and health.Some detection indicators of the human body are of great significance for the assessment of people's health. Some of the body indicators currently agreed by the medical community and relevant research institutions include: Body Mass Index (BMI), Weight (kg)/height meter (m2).), Its normal reference value is: 18.5-23.9; Upper limit of abdominal fat accumulation: waist circumference of female is less than 80 cm, waist circumference of male is less than 85 cm;Visceral fat area (abdominal interface) is less than 100 cm2 ; Carotid Intima-media Thickness (IMT), whose normal value is less than 0.9 mm; Pulse Wave Velocity (PWV) is An index for evaluating vascular arterial elasticity. Ankle arm PWV greater than 14 m/s indicates an increase in systemic arterial stiffness; The diagnostic criteria for hypertension is greater than 135/85 mmHg (family blood pressure) or greater than 140/90 mmHg (outpatient blood pressure); Blood lipid test: (1) Normal reference value of total cholesterol (TC): 2.90-5.68 mmol/L, increased from 3.63mmol/L to 5.18-6.19 mmol/L, the risk of ischemic cardiovascular disease is higher than that of TC<3.63 mmol / L increased by 50%; (2) Normal reference value of triglyceride (TG): 0.57-1.71 mmol/L, (3) Low density lipoprotein (LDL-C) normal reference value: 0.00-3.36 mmol/L, ideal level: <2.60 mmol/L, (3) The normal reference value of high-density lipoprotein (HDL-C) is: 1.09-1.92 mmol /L. Many chronic diseases are related to lack of exercise. The determination and control of physical activity is very important. For cardiopulmonary function status-6 minutes walking test (6MWT), there are reports that the median value for healthy women is about 500 meters and the median value for healthy men is about 580 meters. Mild heart failure 6MWT is greater than 450 meters. Extreme heart rate of exercise (MHB): (220-Age) times/minute, exercise must reach fat burning heart rate above 60% MHB; Exercise to improve the cardiopulmonary heart rate must reach 70%-85 % MHB. Some of the human detection (normal) reference values are created for general population statistics. For individuals, within the normal range does not necessarily mean that the physical condition is normal or there is no hidden danger. To this end, this article proposes the definition of “healthy ideal baseline value" and proposes to keep the body detection value at "health ideal baseline value”. A small fluctuation near the “healthy ideal baseline value" is an important measure to maintain health. The application of “health ideal baseline value” is explained with some examples of physical detection values. Some suggestions are put forward for reference. Expect people to use them to their physical state and trends haave better understanding and control.
