The initial weight value is subtracted from the muscle and fat weights to obtain the bone weight, and then the bone weight In bone density bone volume worth to finally obtain the user's body composition ratio of the initial value, wherein the initial value of the composition ratio of body muscle, fat, and the volume ratio of bone. In a specific embodiment, the processor may be connected to a cloud database and compare the data input by the user with multiple data in the cloud database to calculate a more accurate initial body composition ratio value.
請繼續參閱圖4,完成步驟S1後,接著進行步驟S2:經過一第一時間後,計算一微小電流通過使用者體內之阻抗值,並且依據阻抗值計算使用者之身體組成比例值。步驟S2執行於步驟S1經過一段時間後,第一時間可以為一天、一個禮拜、一個月或任何使用者想量測體重以及身體組成之時間,相似於步驟S15,處理器透過微小電流通過身體的阻抗值配合個體資料計算使用者當下的肌肉及脂肪體積,並且由肌肉和脂肪的固定密度計算肌肉與脂肪重量,之後,使用超音波裝置測量使用者之骨骼密度。其中,若骨骼密度不變則可以假設骨骼重量相同,若骨骼密度改變則回到步驟S1重新體重(一般來說,骨骼密度值短時間之內不會改變),最後得到使用者之身體組成比例值,其中,身體組成比例值為肌肉、脂肪以及骨骼之體積比。 Please continue to refer to FIG. 4. After step S1 is completed, proceed to step S2: after a first time, calculate the impedance value of a minute current passing through the user's body, and calculate the user's body composition ratio value based on the impedance value. Step S2 is performed after a period of time in step S1. The first time can be one day, one week, one month, or any time when the user wants to measure body weight and body composition. Similar to step S15, the processor passes a small current through the body. The impedance value is matched with the individual data to calculate the current muscle and fat volume of the user, and the fixed density of muscle and fat is used to calculate the muscle and fat weight. Then, the ultrasound density of the user is used to measure the bone density of the user. Among them, if the bone density is unchanged, it can be assumed that the bone weight is the same. If the bone density is changed, return to step S1 to re-weight (in general, the bone density value will not change for a short time), and finally obtain the user's body composition ratio Value, where the body composition ratio is the volume ratio of muscle, fat, and bone.
請繼續參閱圖4,完成步驟S2後,接著進行步驟S3:處理器比較步驟S1計算之初始身體組成比例值以及步驟S2計算之身體組成比例值,並且依據兩者的差值計算使用者的體重變化量。 Please continue to refer to FIG. 4. After completing step S2, proceed to step S3: the processor compares the initial body composition ratio calculated in step S1 and the body composition ratio calculated in step S2, and calculates the user's weight based on the difference between the two The amount of change.
請繼續參閱圖4,完成步驟S3後,接著進行步驟S4:處理器利用初始體重值以及體重變化量計算使用者之一當前體重值以及一估算的未來體重值。例如,若體重變化量表示步驟S2計算之身體組成比例值之肌肉體積比步驟S1計算之初始身體組成比例值之肌肉體積多了5立方公分,則以肌肉密度1.06g/ml計算則可以推算多了5.3g(5×1.06)的肌肉,再加上初始體重值則可以計算出當前體重值。而透過每次量測的身體組成比例變化量,則可以自動推算出未來某個時間點的體重值。之後,處理器可以將計算之當前體重值以及未來體重值顯示於穿戴式裝置或處理器或一行動裝置之顯示螢幕。 Please continue to refer to FIG. 4. After step S3 is completed, step S4 is performed: the processor uses the initial weight value and the weight change amount to calculate a current weight value of the user and an estimated future weight value. For example, if the amount of change in body weight indicates that the muscle volume of the body composition ratio value calculated in step S2 is 5 cm greater than the muscle volume of the initial body composition ratio value calculated in step S1, the calculation can be extrapolated using a muscle density of 1.06g / ml With a weight of 5.3g (5 × 1.06), plus the initial weight value, the current weight value can be calculated. And through each measurement of the body composition ratio change, you can automatically calculate the weight value at a certain time in the future. After that, the processor may display the calculated current weight value and future weight value on a display screen of the wearable device or the processor or a mobile device.
請參閱圖6,圖6係為本發明之計算體重變化量的方法之一具體實施例之步驟流程圖。於一具體實施例中,步驟S4之後還包含步驟S5:經過一第二時間後,重新量測初始體重。步驟S5中的第二時間可以為使用者自行定義的時間範圍,例如一個禮拜、一個月等,於另一實施例中,第二時間可以定義為「當骨骼密度值改變時」,例如若初始量測之骨骼密度值為1g/ml,某次量測時骨骼密度值改變為0.9g/ml,則代表使用者該重新量測體重以校正體重值。於一具體實施例中,處理器可以記錄使用者每次經過重新校正後的體重值與計算的當前體重值之差值,並且調整各項計算因 子以達到更準確的體重計算。 Please refer to FIG. 6, which is a flowchart of steps of a specific embodiment of a method for calculating a change in body weight according to the present invention. In a specific embodiment, step S4 further includes step S5: after a second time has elapsed, the initial weight is measured again. The second time in step S5 may be a user-defined time range, such as one week, one month, etc. In another embodiment, the second time may be defined as "when the bone density value changes", for example, if the initial The measured bone density value is 1 g / ml, and the bone density value changed to 0.9 g / ml during a measurement, which means that the user should re-measure the weight to correct the weight value. In a specific embodiment, the processor may record the difference between the user's weight value after each re-calibration and the calculated current weight value, and adjust various calculation factors to achieve a more accurate weight calculation.
