- Pole dance: More than sport. An insight in portuguese realityPublication . Sousa, Jenny; Oliveira, Lisete TrindadePole dancing is a sport with a specific competition code of points, divisions and categories, rules and penalties. However there are other reasons beyond the practice of sport that led individuals to seek and maintain in pole dance. This modality presents unique characteristics that distinguish it from other sport activities and is gathering more and more support in Portuguese context. As so, and given the few studies devoted to Portuguese reality, the aim of this investigation was to deepen the knowledge about the practice of pole dancing in Portugal, knowing the motivations that lead the individuals to initiate themselves in this modality, the benefits and the motives they recognize to continue practicing. In data collection, the questionnaire survey was privileged, made with closed-answer and open-answer questions, addressed to Portuguese pole dancing schools and to the Associação Portuguesa de Varão Desportivo (APVD), having participated in the study a total of 99 persons. The results obtained through statistical content analysis, revealed that the motives to initiate this practice are varied and reflect some lack of knowledge of this modality, as curiosity and the wish to experience something new and that it is disruptive emerges as primary purposes. When benefits are addressed, psychological, physical and social gains emerge. When referring the motives to stay in the pole dance, personal overcoming is highlighted as the main reason.
- How weekly monitoring variables influence players’ and teams’ match performance in elite futsal playersPublication . Ribeiro, João Nuno; Monteiro, Diogo; Sampaio, Jaime; Couceiro, Micael; Travassos, BrunoThis study aimed to investigate how weekly training load constrains the performance of players and teams in official futsal competitions. Data from a professional male team were collected during two seasons (46 weeks). The applied monitoring system analysed the training load (as measured by session perceived exertion, sRPE), the total recovery status (TQR), the well-being score (WBs) and the variability of neuromuscular performance during each week (CMJ-cv). In addition, the performance was assessed for all the matches. A path analysis model was performed to test the associations across variables. Results from the path analysis model revealed that it explains 31% of the teams’ performance. In general, the results show that previous team performance has no significant effects on the training week. A significant negative relationship was found between CMJ-cv and match performance (β = -.34; CI95% -.359 to -.070), as well as a significant negative relationship between players’ match performance and the team’s match performance (β = -.55; CI95% -.292 to .740). Regarding indirect effects, only a negative association between CMJ-cv and team match performance via players’ match performance (β = -.19; CI95% -.342 to -.049) was identified. The small variation of the weekly CMJ (CMJ-cv) seems to be a key variable to monitor and explain both player and team performance. Based on this model, and only looking at the physical variables, it was possible to explain 31% of the team’s performance. Longitudinal and multi-team studies should be conducted to integrate other technical, tactical and psychological variables that allow the level of understanding of players’ and teams’ performance to be improved.
- Supercritical fluid technology for agrifood materials processingPublication . Braga, Mara E M; Gaspar, M. C.; de Sousa, Hermínio CSupercritical fluid technology has been applied in the food area for processing and preserving food products and/or monitoring the food quality, with known advantages. The main solvent used at supercritical conditions for food applications is carbon dioxide. Some examples are presented, from the traditional decaffeination of coffee up to the micronization of vanilla, passing through innovative processes such as the extrusion of protein-based snacks and drying of beetroot. The gap between research and industries is addressed, mainly due to a lack of data about food chemical changes that may occur during some processes, as well as technical data. However, this is an area in clear expansion and probably, in the future, we will have a menu composed of meals prepared by supercritical methods.
