[Objective] This study examined the effects of resting metabolic rate (RMR), sleeping metabolic rate (SMR), and diet-induced thermogenesis (DIT) during acute weight loss in elite male wrestlers.[Methods] Subjects were elite male wrestlers (n=6), who were instructed to reduce the body weight in seven days. RMR, SMR, and DIT were measured by indirect calorimetry in normal training phase and after rapid weight loss. Body composition and energy intake were also measured.[Results] Energy intake significantly decreased in rapid weight loss phase (P<0.05). After the rapid weight reduction, percent reduction of body weight (-4.4%), fat mass (-17.5%), and total body water (-3.2%) significant compare with that of normal training phase (P<0.05). RMR(-15.2%), and SMR (-11.8%) significantly decreased during acute weight loss (P<0.05). DIT(-89.4%) tended to be decrease during acute weight loss.[Conclusion] The present study suggests that rapid weight loss in elite male wrestlers causes decreases in RMR and SMR.

<p> 日本レスリング協会では、「インテリジェントレスラーの育成」を理念にアスリートとしてのキャリアと人としてのキャリアの両立(Dual Career)の支援を目指した新たな発掘・育成システムの構築を推進している。本事業の一環にて、カデット世代(U-18)の国内育成プログラムに参加している最も優秀なタレントを選考し、海外育成プログラムへ派遣した。同プログラムにおいては、ライフスキル(以下、LS)の獲得を促すためGROWモデル(Goal・Reality・Options・Will)による個別ミーティングを複数回実施した。2015年度においては、男子フリースタイルのタレント3名をロシア(クラスノヤルスク)、男子グレコローマンスタイルのタレント3名を韓国(釜山)、女子のタレント4名をアメリカ(コロラドスプリングス)へそれぞれ派遣した。本研究ではLS評価尺度を用いて、海外育成プログラムの出発時点と帰国時点のLS獲得レベルを比較することで、GROWモデルを用いた海外育成プログラムがLS獲得に与える影響を検討した。分析の結果、特に「コミュニケーション」(t(9)=1.87、p<.10)と「礼儀・マナー」(t(9)=1.65、p=.13)において、他のLSに比べ平均値の大幅な上昇が見られた。</p>

Establishment of the Athlete Development System (ADS) has been positioned as an important effort of the success in high performance sport. The review paper summarized the initiatives of the gov-ernments and national sport organizations to establish the ADS after the Tokyo 1964 Olympic Games. Also, we analyzed the current situation of the ADS in Japan. As a result, the definition of the ADS has changed from explaining a direct relationship between training volume/intensity and performance to taking a systematic approach incorporating many factors related to the ADS. Since 2010, each na-tional sport organization has formulated a medium to long-term strategic plan. However, we need to reaffirm that the current strategic plan is focusing on the final stage of achieving medals at major competitions. We suggest that the quality and effectiveness of each of sport organization is positioned as an important effort of the success in high performance sport. The review paper summarized the initiatives of governments and sport organizations’ youth programs, which are the foundation for the success at the senior level. If the national sport organizations were not able to improve their athlete development pathway program, it would not lead to the sustainable ADS in the near future. Therefore, looking ahead to 2020 and beyond, each sport organization needs to establish a unique Japanese athlete development framework by considering the background of Japanese society.

The purpose of this research was to consider the possibility for the development of evidence-based policy making (EBPM) in the field of sport through the case of Coronavirus disease 2019 (COVID-19). COVID-19, originated in Wuhan, China, has rapidly spread world-wide and severely impacted society in several fields. High performance sport is no exception. The Tokyo 2020 Games, professional leagues and many competitions had to be suspended or postponed. Most of the training centers around the world partially or completely closed to protect athletes’ health and safety. Furthermore, restrictions of public life such as quarantine affected the physical and psychological conditioning of athletes. The planning and preparation to return to sport activities was therefore considered extremely important. The International Olympic Committee (IOC) developed a strategic partnership with the World Health Organization (WHO) to provide evidence-based information and advice to sports organizations. WHO published sport-specific guidelines and the IOC encouraged International Federations (Ifs) to follow WHO’s guidance. With the establishment of R&D Blueprint in 2016, the WHO is in a position to coordinate a global coalition of experts to accelerate the R&D process which develops new norms and standards during epidemics such as COVID-19. On one hand, various sporting organizations (government agencies, training centers, Olympic and Paralympic Committees), collaborated and shared information for decision-making. There was, however, concern for the lack of research-based evidence. The experience of COVID-19 showcased the importance to prepare and plan for the future based on evidence generated through research. Until now, evidence-based policy making (EBPM) has been rarely discussed in the field of sport. The High Performance Sport Center (HPSC) is the only one organization that owns a database storing various information related to sport in Japan, and therefore has the potential to foster the implementation of EBPM in the field of sport by utilizing its database.
