The said motion EE that externally does work _ActComputing unit calculates the external institute of motion work, utilizes the body weight W of human body personalizing parameters and the acceleration of acceleration transducer collection to calculate.Acceleration on three directions of acceleration transducer collection campaign (being expressed as X axle, Y axle and Z axle); Record X through pick off; Y axle acceleration value is the acceleration on this direction in the human body motor process just; The Z axle records the influence that acceleration will receive gravity acceleration g, therefore when calculating, must eliminate the effect of g.

Preferably, it is the product of power and displacement that the present invention adopts the method for calculating merit in the kinesiology, promptly

EE _act=F×S×cos(θ)

EE in the formula _ActBe power institute work, F is the size of power, and S is the displacement on the force direction, and θ is the angle of power and displacement.Because power is consistent with the direction of displacement, therefore when computing power institute work, use respectively

EE _act=F×S

S in the formula must calculate the displacement on the place direction of exerting oneself earlier for what change when calculating merit.S during motion can be expressed as

$S={\∫}_0^T{\∫}_0^t\mathrm{adndt}+V_0\×T$

S in the formula is the displacement on the motoricity direction, and T is motion total time, and t is the real time acceleration value that acceleration transducer is gathered for the integration period of motion, a, and n is an integration variable, V ₀Initial velocity during for motion, preferred initial velocity is 0.

${\mathrm{EE}}_{\mathrm{act}}={\∫}_0^T{\∫}_0^{t}W\×a^2\×(V_0+a\×t)\mathrm{dndt}$

EE in the formula _ActBe motion institute work, T is motion total time, and t is the integration period of motion, and W is subjects's a body weight, and t is the real time acceleration value that acceleration transducer is gathered for the integration period of motion, a, and n is an integration variable, V ₀Initial velocity during for motion, preferred initial velocity is 0.

Acceleration in the human motion process contains the almost-periodic function of multiple harmonic for being first-harmonic frequently with the step, must take absolute value when calculating integration with such function, otherwise positive negative acceleration can be cancelled out each other to time integral

${\mathrm{EE}}_{\mathrm{act}}={\∫}_0^T{\∫}_0^{t}W\×a^2\×(V_0+|a|\×t)\mathrm{dndt}$

EE in the formula _ActBe motion institute work, T is motion total time, and t is the integration period of motion, and W is subjects's a body weight, and t is the real time acceleration value that acceleration transducer is gathered for the integration period of motion, a, and n is an integration variable, V ₀Be initial velocity, preferred initial velocity is 0.

Because not only with to record real-time acceleration relevant on the Z-direction, also the gravity acceleration g with human body is relevant, so in calculating, will eliminate the gravity acceleration g function influence for the acceleration on the Z-direction.If record the real-time acceleration of Z axle greater than 0, show that this moment, the gravity center of human body moved upward, total acceleration is a on Z-direction so _Z-g, at this moment on the Z-direction acting as shown in the formula

${\mathrm{EE}}_{\mathrm{act}}={\∫}_0^T{\∫}_0^{t}W\×{(a_z-g)}^2\×(V_0+|a_z-g|\×t)\mathrm{dndt}$

G in the formula is an acceleration of gravity.

If record Z axle real time acceleration less than 0, the center of gravity that shows human body this moment is that total acceleration is a on Z-direction so downwards _Z+ g, at this moment to attend institute's work following for Z-direction

${\mathrm{EE}}_{\mathrm{act}}={\∫}_0^T{\∫}_0^{t}W\×{(a_z+g)}^2\×(V_0+|a_z+g|\×t)\mathrm{dndt}$

In sum, utilize the acceleration and the body weight W that measure to calculate externally acting EE _ActBy calculating the sum of being done work on X axle, Y axle and three directions of Z axle, doing work on said calculating X axle, Y axle and three directions of Z axle is respectively:

${\mathrm{EE}}_{\mathrm{xyz}}={\∫}_0^T{\∫}_0^{t}W\×{\mathrm{ACC}}^2\×(V_0+\mathrm{ACC}\×t)\mathrm{dndt}$

Wherein, a _XBe the acceleration that the X axle is measured, a _YBe the acceleration that the Y axle is measured, a _ZBe the acceleration that the Z axle is measured, g is an acceleration of gravity, and symbolic operation is got in sym () expression, when on calculating X axle, Y axle and three directions of Z axle, doing work, adopts following formula to carry out respectively, when calculating externally acting EE _ActThe time, the addition of doing work on X axle, Y axle and three directions of Z axle is promptly got.For example shown in Figure 4, the external preferred embodiment flow chart that does work when moving for calculating passes through following formula earlier; Utilize the acceleration of human body body weight and measurement, calculate externally acting on X axle and the Y axle, when calculating Z axle is done; Make a decision the Z axle and whether measure acceleration, in view of the above the acceleration of measuring is revised, and then calculate the Z axle and externally do work greater than 0; With three direction acting additions, promptly obtain externally acting EE _ActWhen calculating integration, because the common frequency of human motion is 20HZ, frequency acquisition should be greater than 40HZ, and frequency acquisition of the present invention is 50HZ, and the time cycle of gathering the motion brief acceleration is 0.02s, so the Δ t will measure the time is taken as 0.02s.

Consider the physiologic effect of human body acting, promptly the people can feel tired in walking or after a period of time of running, if but on pedal, come the above action of repetition can feel same fatigue with identical time and identical stride.The physiologic effect that on the mechanics brow landing motion is produced can firmly represent the integration of time, promptly

${\mathrm{EE}}_{\mathrm{act}}={\∫}_0^T\left|a\right|d\left(t\right)$

EE wherein _ActBe motion institute work; T is total time of motion; A is the acceleration of motion that collects; T is an integration variable.Firmly long-pending mode is calculated motion, and externally acting is simpler than said method calculating, but the precision of its calculating is lower than said method.
