According to description above it is found that long-jump training device provided by the present embodiment of the invention is equipped with dynamometer, surveys When device and velometer so as to which all data index of sporter during long-jump is effectively detected understand its deficiency, it is real Training with a definite target in view is applied, sports achievement is improved.
As shown in Fig. 2, as a preferred embodiment, on the bottom plate 1, the position adjacent with the pedal 2, if There is the first fixed link 4, the height of first fixed link 4 is 0.4m-0.6m.The chronometer 5 is installed on first fixed link 4 Top.
Preferably, the height of first fixed link 4 is 0.5m, the chronometer 5 is installed on first fixed link 4 Top.The elevation carrection is accurate, and when avoiding pushes pedals, the dust that ground raises interferes testing result.
In the present embodiment, the chronometer 5 preferably uses light chronometer.In addition, the chronometer 5 uses infrared receiver Bashertron starts timing when infrared ray is separated, and after partition is opened, stops timing.It can accurately be examined using light chronometer 5 Survey the time of sporter's pushes pedals.
As shown in Fig. 2, as a preferred embodiment, on the bottom plate 1, and the position adjacent with the pedal 2, It is provided with the second fixed link 6 side by side with first fixed link 4, the height of second fixed link 6 is 1m-1.4m.The survey Fast device 7 is installed on the top of second fixed link 6.
Preferably, the height of first fixed link 4 is 1.2m.
The velometer 7 for example may be selected sport and hold radar meter, model XA.00-BUSHNELL (Beijing Zhuo Chuan Electronic Science and Technology Co., Ltd.).
TC-1 spring dynamometer or SL-1 type digital force-measuring instrument for example may be selected in the dynamometer 3.
As an optional embodiment, in the present embodiment, on the bottom plate 1, and one far from the pedal 2 Side is additionally provided with third fixed link 8.The display screen 9 is fixed on the top of the third fixed link 8, the display screen 9 and the survey Fast device 7, chronometer 5 and dynamometer 3 connect, and for showing every Testing index, facilitate observation.Meanwhile the display screen 9 also has Data input function, to indexs such as input motion person number, body weight parameters, long-jump distances.
In the present embodiment, the power supply 10 is fixed on the bottom plate 1, and is set to side by side with the display screen 9 Side far from the pedal 2, for powering for the display screen 9, velometer 7, chronometer 5 and dynamometer 3.
It should be noted that all statements for using " first ", " second ", " third " are in the embodiment of the present invention Distinguish three non-equal entities of same names or non-equal parameter, it is seen that " first ", " second " and " third " only for The convenience of statement should not be construed as the restriction to the embodiment of the present invention.
Fig. 3 is the structural block diagram of long-jump training device involved in the embodiment of the present invention;Fig. 4 is to use reality of the invention Apply the flow diagram of long-jump training device involved in example.As shown in Figure 3 and Figure 4, when using involved by the embodiment of the present invention And long-jump training device when, which is set to 11 side of sand pit, and detected in the steps below:
Step S1: opening power supply 10, by display screen 9, input motion person number and body weight parameters M.
Step S2: after sporter's take-off, complete detection is carried out to the stress of the pushes pedals of the secondary long-jump, time, speed. Wherein, sporter tramples the 2 movement velocity V of pedal when velometer 7 detects take-off;Sporter steps on when chronometer 5 detects take-off Step on the time T of the pedal 2;Dynamometer 3 detects the stress F of the pedal 2 when take-off.
Step S3: after terminating the secondary jigging separation, measuring the secondary long-jump distance S, and passes through display screen 9, input The distance S of the secondary jigging separation.
Step S4: control arithmetic element is received, is stored, velometer 7, chronometer 5 and dynamometer 3 described in operation detect Data, and input sporter weight and the secondary long-jump range data;And it is updated to following formula:
S=A*F*V/T/M ... (1)
Wherein: S is the distance of long-jump;A is correction factor, determines correction value according to different type human and environment, the value It to be obtained by a large amount of exercise testing;Movement velocity when V is the take-off measured by the velometer 5;F is by dynamometer The stress size of pushes pedals when the take-off of 3 detections;T is the time of the pushes pedals detected by tester 7;M is sporter's Own wt.
S is related with V, F, T and M, and interrelated between each parameter.Wherein, movement velocity V is faster, jumps remoter;It steps on Plate to put forth effort F bigger, jump also remoter;The time T that pedal is puted forth effort is shorter, then jumps remoter;Conversely, itself weight of sporter The amount M the heavy more jumps not far.
Step S5: sporter repeats jigging separation, repeats step S2 to step S4, the control arithmetic element 12 acquisition multi-group datas, substitute into formula (1), and carry out data sunykatuib analysis, determine each sporter's for different motion person Stable correction factor A.
Step S6: display screen 10 shows the exercise data and coefficient A value of each long-jump of sporter.
Preferably, the distance S can also be measured by range finder, which connects display screen 9 and power supply, and sporter jumps After remote, range data is input to control arithmetic element 12 and is stored and calculated, and is shown in display screen 9.The control Arithmetic element 12 may be disposed in the display 9, to reduce the volume of device.
Long-jump is repeated in the long-jump training device of sporter through the invention, obtains related F, V, T of several groups etc. Detection data, and be fitted by means of above-mentioned formula (1), in this way, it is possible to embodiment through the invention with a definite target in view Related long-jump training device detects the deficiency of sporter, is improved to reach ideal achievement.
From the above it can be seen that long-jump training device provided by the invention, by the dynamometer of setting, chronometer and Velometer, the indices during each long-jump of comprehensive detection sporter, and the specific of indices is shown by display screen Testing result facilitates observation.Furthermore sporter can be effectively instructed by the data that the long-jump training device detects, is found Its shortcoming improves and reaches ideal achievement so as to carry out training with a definite target in view, make sporter lack to walk it is curved Road.
It should be understood by those ordinary skilled in the art that: the discussion of any of the above embodiment is exemplary only, not It is intended to imply that the scope of the present disclosure (including claim) is limited to these examples;Under thinking of the invention, above embodiments Or it can also be combined between the technical characteristic in different embodiments, and there are different aspects present invention as described above Many other variations, in order to it is concise they do not provided in details.Therefore, all within the spirits and principles of the present invention, Any omission, modification, equivalent replacement, improvement for being made etc., should all be included in the protection scope of the present invention.
