When starting, take a piece of wood in your hand, run to the other side and bend down to change another piece, then run to the starting line to change one piece, then run to the other side to change the last piece, and finally come back across the starting line.

The following is the content of copying the physical fitness test standard:

Site equipment: There are several linear runways, with the length of 1 0m, and a line is drawn 30cm away from both ends of the runways (S 1 and S2) (Figure1). Each lane has 3 boards (5cm× 10cm), of which 2 boards are placed on the horizontal line outside S2 line, and 1 board is placed on the horizontal line outside S 1 line, and there are several stopwatches.

Test method: the testee starts to stand, and starts from the outside of S 1 line after hearing the call. When he ran to the front of the S2 line, he picked up a building block with one hand and ran back. When he ran to the front of S 1 line, he exchanged building blocks and then ran back to S2 to exchange another building block. Finally, he rushed out of the S 1 line with the block and recorded the whole time. Records are recorded in seconds, with one decimal place reserved. When the second decimal place is not "0", it is 1.

Note: When the subject picks up and puts on the block, his feet cannot cross the lines S 1 and S2.
