  • the load transfer member 21 is preferably adjustable in its height.
  • the length of the load transfer member 21 itself may be adjusted, that is, the load transfer member 21 may be rotated to be adjusted in its height.
  • auxiliary members (not shown) having different lengths may be coupled to the load transfer member 21, and, in some cases, the height of the load transfer member 21 may be adjusted by coupling an auxiliary member having an adequate length thereto. In the latter, the auxiliary member coupled to the load transfer member 21 is brought into contact with the uppermost weight 41, and the auxiliary member receives the vertical upward load from the weight 41 and transfers the received vertical upward load through the load transfer member 21.
  • the load transfer member 21 is adjustable in its height, for example, in case of weight instruments 40 further having a protruding hole 45 (see Fig. 4) which vertically protrudes from the periphery of a through hole (not shown) of the uppermost weight 41 and through which the guide bar 46 passes, after the height of the load transfer member 21 is adjusted by using an adequate auxiliary member according to the height of the protruding hole 45 for each weight instrument 40, the one repetition maximum measuring unit 30 is coupled to the weight instrument 40.

  • one which can measure compressive force is used.
  • the shape thereof is not particularly limited as long as it can measure compressive force, that is, the vertical upward load from the weight 41.

In this case, it is impossible to measure the one repetition maximum.
  • the minimum weight state described above is not necessarily set.
  • An adequate weight state may be set according to the subject, that is, different weight states may be set according to sexes or ages. Further, the same weight state may be set for every one.
