ABSTRACT
We investigated the effect of anodal transcranial direct current stimulation (tDCS) over the right dorsolateral prefrontal cortex (rDLPFC) on the sensitive decision making of female team sports referees. Twenty-four female referees voluntarily participated in this randomized, double-blind, crossover, and sham-controlled study. In three different sessions, participants received either anodal (a-tDCS; anode (+) over F4, cathode (-) over the supraorbital region (SO)), cathodal (c-tDCS; -F4/+SO), or sham tDCS (sh-tDCS) in a randomized and counterbalanced order. a-tDCS and c-tDCS were applied with 2 mA for 20 min. In sh-tDCS, the current was turned off after 30 s. Before and after tDCS, participants performed the computerized Iowa Gambling Task (IGT) and Go/No Go impulsivity (IMP) tests. Only a-tDCS improved IGT and IMP scores from pre to post. The delta (Δ = post-pre) analysis showed a significantly higher ΔIGT in a-tDCS compared to c-tDCS (p = 0.02). The ΔIMP was also significantly higher in a-tDCS compared to sh-tDCS (p = 0.01). Finally, the reaction time decreased significantly more in a-tDCS (p = 0.02) and sh-tDCS (p = 0.03) than in c-tDCS. The results suggest that the a-tDCS improved factors related to sensitive decision making in female team sports referees. a-tDCS might be used as an ergogenic aid to enhance decision performance in female team sports referees.
ABSTRACT
Abstract Aim: This study aims to analyze the perceptions of women who hold leadership positions in sports on female participation as the head coach of the Brazilian women's handball national team. Method: We offer a qualitative case study. The collected data was through in-depth elite interviews. The interviewees' responses were analyzed and interpreted using the construction of categories. Results: The finds show perceptions of the categorization process. Three main categories emerged: 1) Prejudice. The interviewees affirm that the prejudice within the sport has been decreasing over the years. But it remains latent and continues to make difficult the continuity and rise of women in sports. 2) Professional and personal life. The interviewees affirm that Brazil is still a macho country, and even at a lower level, prejudice still exists in the universe of sports. The sport is known as a territory where men produce and demonstrate their masculinity; this favors the perception that coaches are usually men, having specific questions about the women's competence in that position, and that only men would be able to run teams. 3) Competence. The conciliation between family and professional life is a delicate situation, promotes conflicts, and does not favor the rise of women in positions of command. Nevertheless, the difficulty of reconciling personal and professional life, especially in high-performance sports, is necessary to leave home for extended periods for training or competition. Conclusion: The prejudice still is present despite its reduction over the years. The men domain the sports career, and for women, it is necessary to face the glass ceiling and prove their capacity constantly. Women's access to head coach teams, such as the Brazilian adult women's handball national team, is still a significant challenge.
