It is generally believed that an accuracy of a balance utilizing a spring is deteriorated by the influence hysteresis. This paper intends to make it clear that a balance using a spring, if observed independent the principle of measurement, will come under a major influence of hysteresis when measurement made under a balance effected between the gravity and elasticity, while it will be little affected hysteresis if a spring is used as a lever fulcrum and measurement is made under a balance with standard weight. In the latter case, the main cause for dispersion in the case of knife-edge fulcrum is removed with the result that the dispersion may be minimized. Then, various constructions of the fulcrum which a lever is hung by the spring were classified and thus, their respective superiority or inferiority fulcrum in respect to sensitivity and load standing capacity was examined. As the result, an fulcrum of cross flexure was found to be superior because it fully satisfies all of these conditions required. Accordingly, a pendulum balance using such a fulcrum was experimentally manufactured with an application of the Roberval mechanism. Its dispersion, as anticipated, is far less than that of conventional balance using the knife-edge fulcrum.

In recent years, the applications of an idea on muscle synergies have been increasing in terms of a coordinated muscle activities for motions. However, a few studies have discussed the relationship between muscle synergies and dynamic motions. We examined the relationship for squatting, pedaling, and ski turning that have the different reproducibility. Furthermore, we discussed the influence of muscle fatigue on muscle synergies. As a result, the robustness of muscle synergies are different depending on the degree of reproducibility of motions and the synergy profiles and weights are effective to identify the small number of muscles that should be measured. Nevertheless, muscle synergies should be further studied regarding the assessment of muscle fatigue with the ling-term trend and fatigue-related changes in muscle coordination.
