The kinesiological characteristics of press, snatch and jerk, the physical strength and the records of the weight-lifters of the first rank in Japan were chronologically investigated and evaluated by taking into consideration the records of weight-lifting in the international athletic meeting. The summary of the results obtained is as follows: 1) In press of weight-lifting the record got better chronologically, but in movement analysis the remarkable improvement was not observed. 2) In the beginning of press the velocity change rather increased chronologically. Taking into consideration of the annual change of physical strength and weight-lifting record, there could exist a technical change in press, e.g. they came to have the increased tendency to get supplementary strength in the beginning of press by the under extremities. 3) The hypothesis that it will be desirable to have higher speed at S.P. point in proportion to increased weight, does not always hold true in snatch. 4) At 6 events the desistance of jumping back varied from 15 to 25 cm in the almost all subjects. 5) In jerk the acceleration of movement at each point deviated quite a lot, namely, there was found no definite tendency of the acceleration. 6) Trunk and knee angles slightly increased year by year, which could be considered to be as the result of the technical improvement. 7) The A.H.J. of trunk angle at S.P. point during clean movement was the biggest in jerk, next in press and then least in snatch, and the velocity at S.P. point was in the reverse order of the relation of that angle. 8) In muscle strength, pressure of bearing up, side-step, Harvard Step Test, vertical jump, flexibility and Typus Index, a characteristic change could not be observed. 9) In the total record considerable annual increase was observed and smaller difference among the athletes was found. 10) In press, jerk and snatch each record was in the following order : 1. press, 2. jerk and 3. snatch. Among those 3 items the increasing ratio of press was the biggest and the others were smaller than that and almost same each other. 11) Including the records of the international events the lifting marks and the records got pretty better chronologically, and the difference between domestic and foreign records became smaller which meant that the domestic records had come close to the international level. 12) The each annual increasing ratio of domestic record of those 3 items was slightly larger than previous one, but in foreign records the annual increasing ratio of snatch was observed to be smaller, compared with those of the other two items. 13) The increasing ratio of the lifting weight per 1 kg body weight was about 104% at minimum and about 113% at maximum, compared with that of 1960's record, and it became larger as the weight class became heavier.
