The characteristic of psychological and physical fatigue in university middle-distance runners during a camp SHIODA Toru Summary The purpose of this research was clarifying the characteristic of the psychological fatigue, the physical fatigue and the subjective fatigue in lodging together of the athletics. The evaluation item was a salivary amylase level, body weight, a muscle-rigidity, a subjective fatigue. The measurement was done during a spring camp (6 days) and a summer camp (7 days). 11 middle distance runners of the university top level were measured (five athlete were measured at both camp). The following conclusion was gotten. The loss weight by the perspiration during a spring camp was big beyond expectation. Therefore, in a summer camp, they were indicated to drink water sufficiently. However, in the free watering, the weight decreased roughly. The importance of watering deliberately was confirmed. Several runners felt lack of sleep at the beginning of a camp, and there was a difference among individuals in the adaptation to the environment of a camp. On the other hand, the muscle hardness level changed hardly. A salivary amylase activity level measured with the portable stress meter (cocorometer, NIPRO). During a summer camp, the salivary amylase concentration was rising and the increase of the stress was admitted. Also, it was related to the way of spending in the holiday and the change of salivary amylase concentration. Therefore, the change of the salivary amylase concentration serves as a reference when deciding a holiday in a camp. The psychological fatigue influenced subjective fatigue stronger than the physical fatigue. Sports and Health Science Laboratory, Toyo University,, Hakusan, Bunkyo-ku, Tokyo,, JAPAN
