Lung ability.
Fig. 1 shows the flow chart of aerobic capacity test method provided in this embodiment, as shown in Figure 1, this method includes
Following steps：
Step S102, when receiving test instruction, detection data acquires the wearing state of equipment.
When carrying out aerobic capacity test, subject is needed to carry out sub- maximum dose steady intensity exercise.For example, subject can be with
With free constant speed, running test is carried out on flatter ground, the testing time (running time) is more than or equal to 10 minutes,
The specific running time can be liked according to the habit of user voluntarily to select, and be also possible to 12 minutes of default.In the present embodiment
It is illustrated by taking running in 12 minutes as an example.
During the test, user needs to wear for measuring the tests such as heart rate data, range data, movement sign data
The data acquisition equipment of data.Data acquisition equipment can be in bracelet shape or be the bracelet with dial plate.Aerobic capacity test
Method can be executed by the microprocessor of data acquisition equipment, data acquisition equipment can also be connect with mobile terminal, by moving
The processor of dynamic terminal executes.
It is illustrated so that data acquisition equipment is the bracelet that wrist is worn as an example, data acquisition equipment can be by inputting mould
Block obtains the test instruction of Client-initiated " running for 12 minutes ".Input module can be touch screen, such as capacitance touch screen, can lead to
The capacitance variations crossed in the predeterminable area more than scheduled duration determine the compressing time of user.Such as user clicks the touch of bracelet
Screen, into the test main interface of " 12 minutes run ", any point or specified region in main interface are tested in user's long-pressing, as into
Enter the test instruction of test, microprocessor obtains the long-pressing movement of " running for 12 minutes " test main interface, as obtains test
Instruction.
When being moved, each sensor of data acquisition equipment is moved for obtaining corresponding signal to each sensor
Desired signal there are different degrees of influence, good wearing state (be worn on the flat body surface for having good blood fortune,
But loose not tension) signal qualities such as preferable heart rate, movement can be obtained, effective test data may further be obtained.
After user initiates the aerobic capacity run for 12 minutes test, it can be set using the acquisition of the following two kinds mode detection data
Standby wearing state.
First way is：Data acquisition equipment can more than be uniformly arranged multiple range sensors, if it is each distance pass
The distance value that sensor measures is respectively less than or is equal to preset distance value, it is determined that the wearing state of data acquisition equipment is good.Example
Property, it is illustrated with two range sensors, two range sensors can be set at the both ends of bracelet, measure bracelet respectively
Two positions at a distance from human body.The distance value d1 and d2 obtained according to two range sensors, assesses the wearing shape of bracelet
State.If d1, d2 are more than preset distance value D1, it is believed that relatively loose, data acquisition equipment is not worn or worn to bracelet
Prompting can be issued the user with, adjustment wearing mode is prompted.If d1 or d2 is greater than preset distance value D1, and the difference of d1 and d2 is big
In equal to preset distance value D2, it is believed that wear inclination, then issue the prompting of adjustment wearing position.If d1 and d2 is respectively less than or waits
In preset distance value D1, alternatively, d1 and d2 is respectively less than or is equal to preset distance value D1, while the difference of d1 and d2 is less than preset distance
Value D2 thinks that the wearing state of data acquisition equipment is good simultaneously, prompts to enter test.
The second way is：Data acquisition equipment includes the dial plate being connected on bracelet, is provided with pressure sensing on dial plate
Device, if the pressure value that pressure sensor measures is within pre-set pressure range, it is determined that the wearing shape of data acquisition equipment
State is good.For example, the quadrangle (or symmetrical both sides) of rectangular dial plate bottom case is provided with pressure sensor, perception data is acquired to warp
Whether the stress level received is consistent, the data of verifying and calibration range sensor.When the pressure value that pressure sensor measures is big
When preset maximum pressure value, it is believed that wear tension, remind user suitably to loosen wearing by the modes such as showing, vibrating.Work as pressure
When the pressure value that force sensor measuring arrives is less than default minimum pressure values, it is believed that wore pine or do not worn, Ke Yitong
It crosses the modes such as display, vibration and reminds user's appropriate adjustment wearing mode.When the pressure value that pressure sensor measures is in default
When within pressure limit, it is believed that the wearing state of data acquisition equipment is good.Pre-set pressure range refers in default minimum pressure
Range between value and preset maximum pressure value.If being provided with multiple pressure sensors on dial plate, each pressure sensor is surveyed
The pressure value obtained is within pre-set pressure range, can determine that the wearing state of data acquisition equipment is good.
Step S104 obtains test data if the wearing state of data acquisition equipment is good.
Good wearing can guarantee that quality is obtained when running preferably tests signal, to guarantee the movement number of test
According to the accuracy of, heart rate data, guarantee the accuracy of test.It is each to pass into test pattern after determining that equipment wearing state is good
Sensor collecting test data.Microprocessor or processor obtain the signal of each sensor acquisition and determine relevant information, such as basis
Heart rate data acquisition module determines heart rate data, determines action classification, movement range, appearance according to movement sign data acquisition module
The action datas such as gesture, action frequency etc..
In an optional embodiment, the heart rate data in the testing time section of data acquisition equipment transmission can receive；
The travel distance data in testing time section are obtained by GPS module.
In another optional embodiment, the heart rate data in the testing time section of data acquisition equipment transmission can receive
With movement sign data；According to movement sign data, the travel distance data in testing time section are determined.Wherein, sign is acted
Data include swing arm amplitude and number of activities；It can be according to the corresponding pass between the swing arm amplitude and average step length of measured in advance
System determines average step length of the subject in current test by swing arm amplitude；Step number is determined according to number of activities；Then basis
Average step length and step number determine travel distance data.
According to movement sign data, the travel distance data in testing time section are determined, according to following principle：
When running traveling, the swing arm of people and the movement of leg have corresponding relationship, and a swing arm has corresponded to primary unilateral side
The traveling (two step numbers) of leg, the number of swing arm correspond to 1/2 step number of user, and the frequency of swing arm has corresponded to 1/2 cadence.Cause
This can determine step number according to wrist equipment.
Further, for the same person, run advance when, swing arm amplitude and its step-length have fixed corresponding
Relationship, and its corresponding relationship meets following rules：Swing arm amplitude is bigger, and stride, that is, step-length is bigger.When jogging, the amplitude of swing arm compared with
Small, step-length is smaller, and when hurrying up, the amplitude of swing arm is larger, and step-length is larger.Therefore, according to the swing arm amplitude characteristic of upper limb, Ke Yixiang
Pair determination people run advance when step-length.Step can be used according to this relationship to obtain range data, i.e., with step
Long * step number obtains range data.And when people is in running, completes a swing arm period with the identical time, the amplitude of swing arm
Bigger, the movable speed of wrist is bigger, and the maximum acceleration value of wrist is bigger, and the variation of acceleration is also bigger.
Equipment used for the first time or it is preceding several times by use, due to do not determine subject swing arm amplitude and average step length
Between corresponding relationship, GPS module can be passed through and obtain travel distance data in the corresponding running period.For example, can make
With the GPS module of bracelet itself, obtains since timer is by zero, terminate the travel distance between 12 minutes to timing.Such as bracelet

In a swing arm period, the position of A point signal wave crest, B point illustrate a trough adjacent with A point and after A point in figure
Position.A, difference, that is, amplitude of the sampled value of B two o'clock is the amplitude for corresponding to subject's swing arm.
Step S106 determines the aerobic capacity for wearing the subject of data acquisition equipment according to test data.
That ran when 12 minutes is completed, and microprocessor or processor can be according to heart rate datas, movement sign data, row
The maximal oxygen uptake of subject, the i.e. aerobic capacity of subject are determined into range data and preset formula etc..
Specifically, step S106 can be divided into following two step：
A. the maximal oxygen uptake predicted value of subject is calculated, the parameter used includes at the end of test every time：Subject
Age age [year], resting heart rate HR_rest [bpm], this time running in stationary time section (last six minutes) heart rate middle position
Heart rate HR_median [bpm], the travel distance data D [km] tested herein；
B. check that this test predicts maximal oxygen uptake if testing time is less than setting number for which time test
Value is used as maximal oxygen uptake, determines the aerobic capacity of subject；If testing time is greater than or equal to setting number, according to current
The maximal oxygen uptake measured in the maximal oxygen uptake predicted value of measurement and the test of specified history, determines the aerobic capacity of subject.
For example, being predicted using the aerobic capacity of the subject measured in specified history test the maximal oxygen uptake currently measured
Value calculates maximal oxygen uptake, and then determines the aerobic capacity of subject.Wherein, history test is specified to can be last test
Or it tests several times recently.
Wherein, the specific method process of step a includes：
(1) according to the age age of the subject obtained in advance, the maximum heart rate reference value of subject is determined.
Maximum heart rate reference value HRmax_ref=207-0.7*age.
(2) resting heart rate of the subject obtained according to maximum heart rate reference value and in advance determines the maximum speed of subject
Spend reference value；Maximal oxygen uptake reference value VO2max_ref=k1*HRmax_ref/HR_rest
Wherein, VO2max_ref is maximal oxygen uptake reference value, and HR_rest is resting heart rate, and k1 is coefficient, and k1 value is desirable
It is worth section (12,18), the preset value of reference is 15.3.
Resting heart rate, also known as quiet heart rate refer in awake, the number of the heartbeat per minute under inactive rest state.
Resting heart rate has corresponded to people in basic metabolism level, and resting heart rate can also reflect the cardio-pulmonary function reserve capabillity of human body, with people's
Aerobic capacity has substantial connection.
(3) according to maximal oxygen uptake reference value, the maximum speed reference value of subject is determined.
Maximum speed reference value V_max_ref=k2*VO2max_ref+m1
Wherein, V_max_ref is maximum speed reference value, and k2 is coefficient value range in (0.04,0.1), reference it is pre-
If value is that 0.06153, m1 is constant value range in (0.5,1), the preset value of reference is 0.7013.
(4) according to travel distance data, the actual average speed of subject is determined.
Actual average speed V_mean=D*5/3.6
Wherein, V_mean is actual average speed, 12 minutes distances at the uniform velocity run out of of subject when D is actual test.
(5) by speed zero and corresponding resting heart rate, the actual average speed and corresponding mesocardia rate, the maximum
Speed reference and corresponding maximum heart rate reference value bring the linear regression function of setting into respectively, determine linear regression function
Characteristic coefficient.
The heart rate of subject and the regression relation formula (regression function) of speed：Y=a X+b
Preferably, vector X is speed, value [0, V_mean, V_max_ref] in regression function；Vector Y heart rate, value
For [HR_rest, HR_median, HRmax_ref], personal feature the coefficient a and b of subject can be determined.HR_median is
Mesocardia rate, the median for the heart rate that can be measured using value as the heart rate stabilization period, that is, the maximum value and minimum of the heart rate measured
The midpoint of value.
(6) according to characteristic coefficient and maximum heart rate reference value, the maximum speed predicted value of subject is determined.
Maximum speed predicted value V_max_pre=(HRmax_ref-b)/a
Wherein, V_max_ref is maximum speed predicted value, and HRmax_ref is the maximum heart rate reference value of subject.
(7) according to maximum speed predicted value, maximal oxygen uptake predicted value is determined.
Maximal oxygen uptake predicted value VO2max_pre=k3*V_max_pre-m2
VO2max has reacted the aerobic capacity this time tested and obtained, and unit is ml/kg/min；K3 is coefficient, value model
It encloses (15,20), the preset value of reference is that the value range that 16.0966, m2 is constant is (10,15), and the preset value of reference is
11.2877。
Coefficient k 1, k2 in above-mentioned formula, the value of m1, m2 are to test (heart when doing one's utmost to run according to a large amount of subject
The maximal oxygen uptake of rate, speed and goldstandard compares, and obtains its corresponding relationship) and obtain, test sample amount is bigger, formula
Coefficient or parameter value can more tend to smaller range, and for any tester, calculated result can more tend to be accurate.When test fills
It sets after being supplied to subject or subject's purchase bracelet product use such as bracelet, developer continues to update the data volume of test
And the value of regulation coefficient parameter, more tend to its calculated result accurately.
In step a, it is known that according to heart rate, the movement velocity, maximal oxygen uptake for testing the suitable a large amount of crowds extrapolated
Between corresponding relationship formula, showed in conjunction with personal movement velocity, heart rate, derive the maximal oxygen with human specific
Oxygen amount estimation/predictor formula, then calculate maximal oxygen uptake, so that it is determined that aerobic capacity.
In stepb, the method smoothly updated can there are many, such as use the methods of Kalman filtering, RLS filter.
For example, the smooth usable parameter of update includes：(specific number of N can be according to specific method for the aerobic capacity predicted value of nearest n times
Determine) the perhaps aerobic capacity value etc. in all aerobic capacity predicted values of history measurement or history test, it can also survey
Speed, heart rate during examination etc. carry out smooth as smoothing parameter.For example, current test is that n-th is tested, the last time is used
The aerobic capacity predicted value of (the N-1 times), VO2max_r [N] be the maximal oxygen uptake that exports when n-th is tested, i.e. subject
Aerobic capacity.VO2max_pre [N] is maximal oxygen uptake predicted value when n-th is tested.One scheduled history test time is set
Number threshold values, such as history test threshold are 3, and processor first judges whether N-1 is more than or equal to 3, such as N-1 >=3, i.e., as N >=4,
VO2max_r [N]=VO2max_r [N-1] * u+VO2max_pre [N] * (1-u)
Such as N-1 < 3, i.e., as N≤3, VO2max_r [N]=VO2max_pre [N]
In above-mentioned formula, the value range of u is [0,1], and the specific value and N of u is related (N is bigger, and u value is bigger), and with
The number of days of this measuring distance last time test is related (interval number of days is longer, and u value is smaller), and when interval, number of days is greater than certain threshold value such as
14 days, it can be updated since 1 and calculate N.
When carrying out the test of race in 12 minutes, heart rate can be gradually increasing at first 3 to 5 minutes, be kept later relatively smoothly
Higher level, HR_median can value counted in rear 6 minutes hearts rate, can also be counted with value in rear 3 minutes hearts rate etc..
When maximum heart rate fingering row exercise load, with the increase of amount of exercise, oxygen demand and heart rate also increase, negative in maximum
When lotus intensity, heart rate reaches when oxygen demand and heart rate cannot continue growing highest level.If detecting user in test
Practical maximum heart rate be more than HRmax, then update HRmax.The method of user's maximum heart rate when determining test:According to wearable
Equipment PPG or ECG principle obtain heart rate, are HR_est_n with each heart rate generated that calculates, then compare HR_est_n with
The size of HR_est_n+1 obtains the larger value, and the larger value is compared with HR_est_n+2, the larger value obtained again same HR_ again
Est_n+2 compares size ... and so on, the practical heart rate maximum value for obtaining measurement period when test is HRmax_test.Than
It can determine no update HRmax compared with HRmax_test and HRmax.
In addition, bracelet is provided with the acquisition methods of resting heart rate, microprocessor obtains accelerometer signal and heart rate signal,
When determining that the smaller human body of activity is in rest state in a period of time according to accelerometer signal, calculated according to heart rate signal
Heart rate at this time is resting heart rate.Preferably, it is waken up from sleep the heart rate of quiet a period of time (such as 10 minutes) with early morning people
For resting heart rate.When carrying out aerobic capacity, the resting heart rate value of the last time measurement, such as number within 3 days or 14 days are used
Value.If bracelet using the resting heart rate that do not surveyed, uses default resting heart rate for the first time, settable default resting heart rate is
Male 60bpm, women 70bpm；Meanwhile user is prompted to measure resting heart rate in rest state, or wear bracelet in sleep
