1. Basal metabolic rate (BMR). Basal metabolism is the lowest energy required to maintain a normal life activity in a human body. When the body is awake and extremely quiet, it is not affected by muscle activity, environmental temperature, food and mental stress. The basal metabolic rate is the speed of basal metabolic activity. Its unit is generally: energy / unit surface area / unit time (such as: KJ / m2 / hour) or energy / time (such as: Kcal / day), kcal / day has a wider range of applications. The more accurate measurement method of basal metabolism is generally “indirect calorimetryâ€, and the subjects are generally required to fast for one night (about 12 hours), and then measured at bed rest on the next day. The measurement environment is also very strict and is generally used in hospitals and laboratories. General calculation formula: Male: BMR = 10 * Weight (KG) + 6.25 * Height (CM) - 5 * Age + 5; Female: BMR = 10 * Weight (KG) + 6.25 * Height (CM) - 5 * Age 161 . 2, body fat rate. Body fat rate refers to the ratio of the mass to body weight of all fat tissue in your body (mainly subcutaneous fat and visceral fat). The body fat rate is better than BMI to explain a person's "fat and thin" situation. Excessive weight is not necessarily fat, and high body fat is the real "fat." In addition, low body fat rate does not mean that your health is good, it can only prove that you are a "skinny." There are many methods for measuring the body fat percentage. There are probably several kinds of common fat: "water weighing method", "bioelectrical impedance method", "leather pleat thickness method". Among them, the more accurate body composition measurement method is the water weighing method, the water weighing method, which is called “water density measurement methodâ€, which can be used to infer the calculation of the relative fat content of the body. The principle of the method is based on “Archimedeâ€. principle". 3. Muscle mass. The body weight component can be divided into two parts: non-fat substances and fatty substances. The muscle content is non-fat substances, which removes about 4% to 6% of inorganic matter. Muscle is a good thing. The bigger the muscle mass, the higher the basal metabolism and the less likely to be fat. 4, body water rate. Body water as a percentage of body weight. This data has a very close relationship with muscle mass. Because the muscle contains a lot of water (about 70%), this indicator can reflect the correct way of weight loss. If the body water rate drops, it will not only damage health, but also make the body The fat percentage is rising. , cheap dog Electronics Toys,big dog Electronics Toys,small dog Electronics Toys Ningbo XISXI E-commerce Co., Ltd , https://www.petspetsdoggze.com
