In recent years, several “no fault or negligence” anti-doping rule violations (ADRVs) have occurred in Japan. The World Anti-Doping Code stipulates that the burden of proof is on the athlete to prove that the result of a positive sample was not “intentional” and that the athlete was “no fault or negligence”. In this study, a web-based survey was conducted to find out what criteria top-level coaches and support staff in Japan use to determine whether a violation is “unintended” and what preparations they make in case a “unintended” ADRV occurs on the “risk and crisis management” point of view. 56 top-level coaches and support staff from 23 sports and 1 NOC support staff responded. The questions covered the level of interest in and understanding of anti-doping activities, the borderline between negligence and “no negligence” in ADRVs, the actions being taken for “unintended” ADRVs, and the preparations being made after a “unintended”ADRV has occurred. The results of the web survey showed that there was a statistically significant difference (5% level) in the determination of whether or not a violation was “unintended” depending on whether or not the prohibited substance was labeled on the package and whether or not the athlete was confirmed it for pharmaceutical products. For dietary supplements, the borderline was whether or not the product had gone through a certification program, which also showed a statistically significant difference (5% level). In terms of coping strategies for “unintended” ADRVs, respondents understood the risks by learning about past violations. However, it has been shown that there is little actions of themselves or guidance to athletes about recording evidence used to track “routes of entry” in case of positive sample. This suggests the need to develop educational programs on “risk and crisis management”.

The present study was conducted to obtain basic information about blood glucose fluctuation and relation with race performance during 100 km marathon. Subcutaneous glucose of one well-trained runner was measured by continuous glucose monitoring system (CGMS) at 5 min interval and blood samples for biochemical analysis were drawn at pre, middle and post of the race. Energy balance during one week prior to the 100 km race was recorded, and the whole energy and fluid intake during the race was analyzed. Blood glucose fluctuated reflecting duration of exercise and energy supply during the race. During the latter part of the race (65–70 km), abrupt declines in blood glucose level, which reflected insufficient carbohydrate intake before the race (119 g), were accompanied by decrease in running speed. The present report suggests that continuous glucose monitoring supplemented with standard nutritional and physiological measurement provides precise and valuable information on runner’s energy state during the ultra-endurance race, and that athletes need to reassess their preparation for the race and planning of energy intake during the race.

本研究では,唾液中のヒートショックプロテイン70(HSP70)が競技選手および高齢者のコンディション評価指標としての有用性について検討した.一過性高強度運動で唾液HSP70が増加することを示した.また継続的な高強度運動で安静時のHSP70は顕著な変動はしないが,その原因として高強度運動に対するHSP70応答の個人差が考えられた.さらに継続的な運動で高齢者の安静時HSP70が高まり,さらにHSP70がT細胞活性経路の亢進メカニズムに関わる可能性が示された.以上より,唾液HSP70によるコンディション評価は,競技選手では個々の変動が異なるため検討が必要であり,高齢者では有用である可能性が示された.
