Abstract

The invention provides a device for measuring sit-and-reach with two middle finger tips as a reference. The two ends of a longitudinal square tube of the device are fixedly connected with one sides of two transverse square tubes respectively. The same ends of the two transverse square tubes are fixedly connected with the lower ends of two long square tube vertical columns respectively. A seat plate is fixedly connected with the transverse square tubes through two short square tube vertical columns fixed to the lower side. One end of the seat plate is provided with a backrest, and a first vernier penetrates through a flat square tube and is provided with a fastening screw. The two ends of the flat square tube are fixedly connected with the upper ends of the vertical long square tube vertical columns respectively. One end of a ruler rod penetrates through a second vernier and is fixedly connected with the inner end face of the first vernier. The inner end face of the first vernier is the zero point of the ruler rod. The upper end of a reference plate is fixedly connected with the lower end of the second vernier and is flush with the end, close to the first vernier, of the second vernier. The device is convenient to use, and the defect that a ruler is fixed to the upper side of a wood box which is 40 cm high, the two arms of a tested person cannot keep horizontal before the finger tips of the tested person push the verniers, and reference is not uniform is avoided.

Description

In two, finger tip is the device of reference measurement sitting body anteflexion

Technical field

The invention belongs to field of sports equipment, particularly to a kind of device measuring sitting body anteflexion。

Background technology

Sitting body anteflexion can reflect flexibility degree and the trunk range of activity of people, is one of National Standard for Sports Training content。Current sitting body anteflexion generally adopts two lower limbs to stretch with sole for zero datum, and in two, finger tip pushes away slip vernier outside chi bar and tests。Owing to above-mentioned test because the long arm of lower limb is short or short legs arm length there are differences, can exist the different disunity of benchmark with sole for zero reference point, institute's test result then can not reflect real trunk bending forwards degree。For better solving the problems referred to above, the Teaching Materials at College level " physical training " of Wu Dongming, Wang Jian chief editor proposes: " the test step of Improvement type sitting body anteflexion; when implementing this test, it is necessary to get out sitting body anteflexion measurer, or chi is placed on above the high wooden case of about 40cm。(1) appropriate warm-up activity is done before measuring。(2) take off one's shoes when measuring。Being sitting on floor and hip, back and head are close to wall, leg stretches completely, the wooden case of the smooth measuring instrument of sole or sitting body anteflexion。(3) when head and back are without departing from wall, by overlapping for the palm of two handss and try one's best and stretch forward, (shoulder encircles circular as far as possible, but now wall can not be left in head and back) then testing person slide the starting point index of dip stick, and make the end of starting point index touch the finger tip of testee, then starting point index keeps fixing in test procedure, does not move again。(4) then head and back may exit off wall, slowly stretch forward and push away vernier (or size) test。" above-mentioned test is correct with finger tip for benchmark principle, institute's test result can reflect real trunk bending forwards degree substantially, but existing problems are；A, tester are sitting in floor again, and testing person squats down the starting point index of slip dip stick, and makes the end of starting point index touch the finger tip of testee, and it is cumbersome simple and direct not that these operate with method；Above the fixing wooden case high for about 40cm of b, chi, before the finger tip of tester pushes away vernier, two-arm can not keep holding level with both hands, affects the unification of measuring basis。Now lack the device of a kind of simple and direct solution the problems referred to above。

Summary of the invention

For solving above-mentioned background technology Problems existing preferably, the present invention provides a kind of device being reference measurement sitting body anteflexion with finger tip in two。

The invention mainly comprises: horizontal square tube, longitudinal square tube, rectangular pipe column, flat pipe, seat board, first vernier, second vernier and chi bar, wherein, it is connected with the side of two horizontal square tubes respectively at longitudinal square tube two ends, the lower end of the rectangular pipe column vertical with respectively in same one end of above-mentioned two horizontal square tubes is connected, seat board is connected with horizontal square tube by being fixed on the short square tube column of following two piece, one end of this seat board is provided with backrest, first vernier traverse flat pipe, this first vernier is provided with trip bolt, the two ends of above-mentioned flat pipe are connected with the upper end of above-mentioned vertical rectangular pipe column respectively, one end of chi bar is connected through the inner face of the second vernier and the first vernier, the inner face of this first vernier is 0 point of chi bar, the upper end of L-shaped datum plate is connected with the second vernier lower end, and align by one end of the first vernier with the second vernier。

When using this device, tester is sitting on seat board leg and stretches, and head back of the body hip is close to backrest, two-arm is held level with both hands and is stretched in two finger tip and touch datum plate, being alignd with 0 of chi bar by the second vernier drive datum plate, screw trip bolt fixed ruler bar, trunk bending forwards pushes away datum plate can measure trunk bending forwards achievement。

The present invention compared with prior art has the advantage that

1, use this device upper and lower seat board ratio to be sitting in floor and get up simple and direct again；

2, testing person adopts erect-position or seat test ratio squat down or are sitting in floor facility；

3, testing person move this datum plate fixed ruler bar determine 0 benchmark than on wooden case mobile fixed ruler determine 0 baseline stability, easily operate；

4, when this datum plate height can meet 0 benchmark, two-arm is held level with both hands, avoids fixed ruler on the wooden case that 40cm is high, and before the finger tip of tester pushes away vernier, two-arm can not keep holding level with both hands, the skimble-scamble drawback of benchmark。
