The described 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-axis, Y-axis and Z axis), record X by sensor, the Y-axis accekeration is the acceleration on this direction in the human body motor process just, Z axis records the impact that acceleration will be subject to gravity acceleration g, therefore must eliminate the effect of g when calculating.

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

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 first the displacement on the place direction of exerting oneself 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 gathers for the integration period of motion, a, and n is 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 body weight, and t is the real time acceleration value that acceleration transducer gathers for the integration period of motion, a, and n is 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 take the step frequency as first-harmonic, 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 body weight, and t is the real time acceleration value that acceleration transducer gathers for the integration period of motion, a, and n is 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 will eliminate the gravity acceleration g function influence in calculating for the acceleration on the Z-direction.If record the real-time acceleration of Z axis 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 acceleration of gravity.

If record the Z axis 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 institute's work is as follows on the 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-axis, Y-axis and three directions of Z axis, doing work on described calculating X-axis, Y-axis and three directions of Z axis 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 X-axis is measured, a _YBe the acceleration that Y-axis is measured, a _ZBe the acceleration that Z axis is measured, g is acceleration of gravity, and symbolic operation is got in sym () expression, when doing work on calculating X-axis, Y-axis and three directions of Z axis, adopts respectively following formula to carry out, when calculating externally acting EE _ActThe time, with on X-axis, Y-axis and three directions of Z axis the addition of doing work and get final product.For example shown in Figure 4, the external preferred embodiment flow chart that does work when moving for calculating, by following formula, utilize the acceleration of body weight and measurement first, calculate externally acting on X-axis and the Y-axis, when the calculating Z axis is done, whether make a decision the Z axis acceleration measurement greater than 0, accordingly the acceleration of measuring is revised, and then calculate Z axis and externally do work, with three direction acting additions, namely 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 that gathers the motion brief acceleration is 0.02s, so the Δ t in the time of will measuring is taken as 0.02s.

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

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

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