In these days, the cure aiming at early recovery is introduced to athletes obstacle encountered in a game or practice process. Taping is the typical means. It aims at mitigation of an ache and at urging the braking effect. Recently, many sports taping aiming at improvement in athletic performance, such as titanium and kinesio taping, is also used. Painkilling and a stillness action are urged to titanium according to the thermotherapy effect. And titanium is said to adjust biological current within the body and produce a relaxing effect. On the other hand, kinesio taping has the effect of increasing our natural ability to heal ourselves and has an effect in relief and medical treatment of an obstacle. The last research examines the physical effects of titanium. It results demonstrate that in the highly reliable group titanium was contributed to improving athletic performance. In this last research, the placebo effect is considered to have acted mentally. In the field of pharmacological, it is said that the placebo effect is based on cognitive evaluation of the cerebral cortex, influences the function of a living body and induces a difference to a vital reaction. In the field of clinical research of psychosomatics medicine, it is said that placebo can improve 30 - 40 percent of a patient\u27s subjective and objective clinical symptoms in wide range diseases, such as sharp pain, asthma, and high blood pressure. Furthermore, in the field of research of sports, it is said that cognitive evaluation to the placebo effect relates to Individual difference by the personality types. However, the quality of the objective data which supports this knowledge is not evaluated strictly. Accordingly, the present research, kinesio taping is shown as it is titanium, it examined whether the athletic performance was raised like titanium. That is, this research examined the justification of the placebo effect. As for kinesio taping, the usage differs from titanium. For the reason, it is thought that there is little influence by the effect of original of kinesio taping. It is surmised that kinesio taping plays the role of a placebo to cognitive evaluation of the placebo effect. The purpose of the present research is the elucidation of the relation of individual difference of the cognitive evaluation by the reliability of titanium and the placebo effect using the kinesio taping. In the first place, drum\u27s temperature, skin\u27s temperature, and brain waves were measured from the physiological side. To the second, the athletic performance was measured from the physical side. To the third, it inquired by using STAI from the psychological side. Our results demonstrate that in the highly reliable group titanium was received favorably and contributed to improving athletic performance
