This study aimed to determine the effects of glucose (Ramune candy) ingestion on cognitive function during esports mediation and concentration during gameplay. The participants were 20 healthy male students who did not play games usually (mean age ± 19.85, standard deviation = 0.96). The experimental design was a randomized, double-blind, placebo-controlled crossover study. The results showed that the ingestion of Ramune candy significantly improved cognitive test scores before and after gameplay. During the esports gameplay, the power percentage of sensorimotor rhythm (SMR, 10-11.75 Hz) waves was significantly higher in the Ramune candy condition than in the placebo condition at 25 to approximately 28 min after the ingestion. These results indicate that the ingestion of Ramune candy effectively maintains a relaxed yet concentrated state during cognitively loaded esports gameplay.

The purpose of this study was to describe, explain, and recommend how women’s professional soccer players and clubs could prepare for second career transitions in a way that minimizes psychosocial crises upon retirement. The Japan Women’s Empowerment Professional Football League (called the WE league) was founded with a mission to contribute towards building a sustainable society through promoting female social participation and enhancing diversity and choice. This study suggested training strategies that could foster second career development in the WE league. These strategies are (a) including theoretical frameworks in second career pathways, (b) the necessity of dual education pathways for Japanese women’s professional athletes, (c) promoting virtual internship experiences for Japanese women’s professional athletes, and (d) recommendations of second career training workshops for professional athletes in the WE League. The WE League and teams should allow professional athletes to improve meaningful skills and knowledge development, multiple experiential learning opportunities, and applicable training on second career development. Due to the paucity of research in this area, it is essential for scholars to further explore potential education and internships opportunities to ease transitions to second careers upon retirement.

The aim of this study was to clarify the attack-defence performances of rugby sevens in 2010-2020 seasons, 4,074 matches. Firstly, averaged try scoring rate and try conceding rate of every teams were drawn in two-dimensions space. Hypothesis 1 was that the achievement values of the upper teams could be clarified. Receiver-Operator-Curve analysis was used to understand how attack-defence indicators correctly diagnose the world rankings. Secondly, the 22m entry attack-defence indicators were drawn in two-dimensional space. Clustering analysis of ranking teams was executed using try scoring rate, try conceding rate, 22m attack-defence indicators. Hypothesis 2 was that the clustering characteristics of upper teams can be clarified by these indexes. Thirdly, network analysis was executed to clarify what kind of characteristic in relationship among the ranking, team performance, and individual performance. The ROC analysis showed the specific achievement level of the top-ranking teams with high accuracy (hypothesis 1). Cluster analysis extracted 4 groups. The gradual attack defence standard values were obtained (hypothesis 2). Network analysis showed the relationship structure among the ranking, the team performance, and the individual performance with some interesting results concerned the dependence tendency changing on the ranking stage (hypothesis 3).
