Requirements for joint activities are varied among many events of sport. Players may have specific joint laxity depending on various training activities. The objective of this study is to clarify the relationship between the joint laxity in passive movement and the type of sport by measuring joint moment-joint angle curves with a modified joint laxity system. Parameter R.O.M. and stiffness β were calculated from the curves obtained. Parameters of 8 volleyball players were compared with those of 11 volunteers. The results disclosed that the joint laxity of volleyball group was less than that of volunteer group, probably due to muscle strengthening exercises. It was also shown that the joint laxity on dominant side was more that non-dominant side in the volleyball group, which was different from the volunteer group. This difference was consiered as a training effect.
