Below further illustrate the details of the energy metabolism measuring method that the present invention is based on Speech input.
As shown in step 101, a user utilizes this input module 2 input one maximal oxygen uptake and personal informations.Maximal oxygen uptake can, in advance by motion, directly be tried to achieve by the measurement of oxygen uptake analyser, or indirectly obtain maximal oxygen uptake information by athletic performance, sex, body weight.Maximal oxygen uptake is called again maximum oxygen receptor long-pending (Maximum Volume of Oxygen Consumed, VO
2max), with respect to individual body weight for humans general purpose single position, be mL/min/kg or L/min/kg.General common direct measurement, can pass through as bicycle ergometer (Cycle Ergometer), treadmill (Treadmill), carry out gradual sports load test (Graded Exercise Testing, GXT), increasing in time exercise intensity (power, the gradient, speed) increases, to analyze maximum oxygen intake in motion.In this step, user, by the touch screen of mobile phone, utilizes user interface 6 input maximal oxygen uptake, body weight and sexes.
As shown in step 102, when this user points out when a resting state is sent a pair of should point out static sound according to one of this reminding module 3, this radio reception module 4 receives this sound when static.In this step, this reminding module 3 is play a plurality of contents of this prompting according to certain rhythm compartment of terrain, and this user sends corresponding sound when static according to these contents at a heat, until cannot continue.When this is static, sound comprises a plurality of and these contents password one to one.For instance, this reminding module 3 sends the short sound of serge sound according to the fixing per minute 120 sounding rhythm of clapping, then user is before setting in motion not, with usually natural speaking volume, at physiologically tolerable, and can not cause in uncomfortable situation, with one breath, the middle mode of can not be air-breathing or interrupting, along with the rhythm of these short sound is read out many group passwords as possible, as the combination of the numerals such as 1234,2234,3234,4234,5234,6234,7234,8234,9234,0234,1234, till cannot continuing.These passwords can be other forms and are not limited to digital combination.Then, the sound that this section of user sends is received by this radio reception module 4, becomes this sound when static.
Then, as shown in step 103, when this user points out when a kinestate sends a pair of motion that should point out sound according to this of this reminding module 3, sound when this radio reception module 4 receives this motion.In this step, with this static radio reception step 102 similarly, this reminding module 3 is play a plurality of contents of this prompting according to certain rhythm compartment of terrain, the short sound of serge sound described above, sound when this user sends corresponding motion according to these contents at the volley at a heat again, until cannot continue.Similarly, during this motion, sound comprises a plurality of and these contents password one to one, and user informed in advance in these passwords, and can be other forms and be also not limited to digital combination.Then, the sound that this section of user sends is received by this radio reception module 4, sound while becoming this motion.
Then, as shown in step 104, when this processor 5 is static according to this sound and when motion sound calculate a relative metabolic rate result.Detailed process state chat as follows.
First, consult Fig. 2 and Fig. 3, when this processor 5 coordinates this arithmetic core 7 static according to this, the time span of sound obtains a sound length ratio when time span of sound and this motion.This sound length ratio is the value of time span time span of sound when static of when motion sound.
Then, by an oxygen uptake rate formula by this sound length ratio calculate a pair of should user the oxygen uptake rate of situation instantly.Meanwhile, by a respiratory exchange rate formula by this sound length ratio calculate a pair of should user the respiratory exchange rate of situation instantly.Then, according to this oxygen uptake rate and respiratory exchange rate, coordinate maximal oxygen uptake, first obtain instantly after oxygen uptake, then calculate this relative metabolic rate result.
Oxygen uptake rate, for user absorbs the index of oxygen ability at the volley, when user movement intensity improves, oxygen uptake rate can have positively related trend relation along with exercise intensity, when arriving 100% exercise intensity, the oxygen volume that unit interval user takes in can approach user's maximal oxygen uptake.It is worth mentioning that, above-mentioned oxygen uptake rate formula is to utilize a regression analysis to produce in advance.And the regression analysis using in the present invention is linear regression (Linear Regression), be the means of often using in statistics, so do not repeated.In addition, a plurality of coefficients and user's sex of this oxygen uptake rate formula have high correlation, so store many group coefficients in the memorizer (not shown) of mobile phone, then this processor 5 coordinates this arithmetic core 7 according to this personal information, be user's sex, select a plurality of coefficients in this oxygen uptake rate formula and respiratory exchange rate formula.In this preferred embodiment, male's oxygen uptake rate=(99.287 * sound length ratio+103.1)/100, and women's oxygen uptake rate=(97.356 * sound length ratio+106.62)/100.If the time span of the static sound of speaking of this male is 15 seconds, during motion, sound length is 9 seconds, male user sound length ratio is 0.6 (9 seconds/15 seconds=0.6), male's oxygen uptake rate=(99.287 * 0.6+103.1)/100=0.4353=43.53%, if the time span of the static sound of speaking of this women is 12 seconds, during motion, sound length is 7.2 seconds, women's user voice length ratio is 0.6 (7.2 seconds/12 seconds=0.6), women's oxygen uptake rate=(97.356 * 0.6+106.62)/100=0.4821=48.21%.
Respiratory exchange rate (Respiratory Exchange Ratio, RER) is user carbon dioxide generating volume (Volume of Carbon Dioxide Produced, VCO at the volley
2) absorb volume (Volume of Oxygen Consumed, VO with oxygen
2) ratio be respiratory exchange rate (RER, VCO
2/ VO
2).Similarly, directly do not measure in the present invention, but obtain with respiratory exchange rate formula.This respiratory exchange rate formula is also to utilize regression analysis to produce in advance.In addition, a plurality of coefficients of respiratory exchange rate formula also have high correlation with user's sex, so this processor 5 coordinates this arithmetic core 7 according to the sex in this personal information, select a plurality of coefficients in this respiratory exchange rate formula.In this preferred embodiment, respiratory exchange rate=-0.3542 * sound length ratio+1.0632 of male, respiratory exchange rate=-0.3549 * sound length ratio+1.0582 of women.If the time span of the static sound of speaking of this male is 15 seconds, during motion, sound length is 9.75 seconds, male user sound length ratio is 0.65 (9.75 seconds/15 seconds=0.65), male's respiratory exchange rate=-0.3542 * 0.65+1.0632=0.8330, if the time span of the static sound of speaking of this women is 12 seconds, during motion, sound length is 7.8 seconds, women's user voice length ratio is 0.65 (7.8 seconds/12 seconds=0.65), women's respiratory exchange rate=-0.3549 * 0.65+1.0582=0.8275.
