- Which factors are related with coaches' perception of young soccer players’ competence: physical fitness, motor coordination or specific skill?Publication . Lopes, Vitor P.; Fortunato, Álvaro; Gonçalves, CelinaA large number of youth sports programs in sport clubs focus on results. However, the success of young practitioners depends on several factors, as generic and specific motor competence that develops with the practice. The sample was boys (N=111) with 10.5(2.48) years of age, who practiced soccer regularly, and their coaches (N=17). Boys were evaluated on physical fitness (multistage aerobic test), motor coordination (KTK) and in specific soccer skills (passing and receiving, juggling the ball, dribbling, and kicking to the goal). A bioimpedance scale were used to determine percent body fat. The coaches were asked about the future success (achieving high performance) of each of their athletes. Multiple regression was performed to identify the variables that predicted the coaches' perception of the competence of young soccer players. Results show that only physical fitness test (cardiovascular fitness) was associated with coaches’ perception of young soccer players competence. In conclusion, cardiovascular fitness was associated with the perception that coaches have of their young soccer players competence, but the specific skill levels and motor coordination were not.
- The relationship between training load, physical performance and physiological adaptations in Rugby football players: a systematic reviewPublication . Paiva, Eduardo; Valentim, Sérgio; Reis, Tiago; Teixeira, José Eduardo; Branquinho, Luís; Fortunato, Álvaro; Forte, PedroApplying appropriate training loads in accordance with the defined objectives promotes optimal physical and physiological adaptations, reduces the likelihood of illness and injury and, therefore, increases the possibility of success during Rugby. The aim of this review was to compile and systematise the information in the literature on the association between training load variables (internal and external) and performance outcomes in Rugby. As such, the main objective will be to conduct a systematic review of the published literature to identify the physical and physiological performance variables in Rugby sport to monitor the training load. Following the preferred reporting item for systematic reviews and meta-analyses (PRISMA) and PICOS approach, the search was adapted and conducted systematically only in the PubMed database, which, in itself, also restricts the search spectrum of the paper, thus conferring a limitation to the present academic work. The search was conducted in PubMed throughout the possible temporal spectrum since there is still little robustness in the literature about rugby sports performance. Articles were selected by pre-defined selection criteria, including observational, randomised clinical and clinical trial studies. After further screening, and based on the inclusion criteria of the papers, the result of the analysis of the relevance of the studies, the final set of analysis resulted in 16 articles. From the studies compiled in this review, there seems to be a strong correlation between the perceived exertion (RPE) and the prescription and definition of the training load applied in Rugby athletes. The RPE reflects the most used and analysed variable throughout all the studies. Several articles reflect a strong relationship between the training load, the inter-individual capacity of each athlete and their tolerance to the load (player load)
- Tipos de bullying mais frequentes no contexto desportivo: uma revisão sistemática da literaturaPublication . Fortunato, Álvaro; Dias, Carlos; Della Casa, Edvaldo; Vaz, Paula Marisa FortunatoO Bullying é uma ação comportamental agressiva e repetida no tempo exercida entre indivíduos com impossibilidade de defesa por parte de um ou mais dos elementos envolvidos na qualidade de vítimas, que tem vindo a ser motivo de grande reflexão no âmbito escolar por parte da comunidade académica. No domínio desportivo também se verificam crescentes preocupações com este fenómeno por parte de pais, treinadores e ademais agentes desportivos. No presente trabalho faz-se um levantamento dos estudos científicos que têm vindo a ser realizados no âmbito do bullying tendo em vista a identificação do tipo de bullying mais prevalente nos desportos coletivos e individuais. Assim, recorreu-se à pesquisa de artigos nas bases de dados B-On, SCOPUS e EBSCO, a partir da qual se obtiveram 76 artigos. Após aplicados os critérios de inclusão e de exclusão, foram analisados 9 artigos, sendo 5 correspondentes a estudos qualitativos e 4 a estudos quantitativos. Foi possível concluir que a investigação recente no âmbito desta temática no desporto é escassa. No entanto, parece haver maior prevalência de bullying físico, verbal e de exclusão social. Os autores salientam ainda a necessidade de se investir na formação dos treinadores e professores para clarificar o conceito de bullying de forma a poder aumentar a probabilidade de uma correta e atempada identificação, e posterior intervenção com vista à irradicação deste fenómeno nefasto para o desenvolvimento dos adolescentes e jovens.
- Autoestima de crianças e Jovens praticantes de futebol: Influência do apoio Social e bullyingPublication . Flor, Sílvia; Fortunato, Álvaro; Gonçalves, Celina; Lopes, Vitor P.Em ambos os sexos, muito pouca associação e, por tanto, nem o supor te social nem o bullying predizem a autoestima.
- Perspetivas de professores do ensino básico e secundário acerca do processo de avaliação do desempenho docentePublication . Fortunato, Álvaro; Vaz, Paula Marisa FortunatoEste estudo teve como finalidade compreender como a avaliação do desempenho poderá estar a ser perspetivada pelos professores dos ensinos básico e secundário. Definiram-se três objetivos: a) perceber a perspetiva dos professores relativamente à existência da avaliação do desempenho docente; b) identificar os problemas que os professores apontam aos processos de avaliação do desempenho docente; c) recolher sugestões acerca do modo como a avaliação do desempenho docente deve ser efetuada. Realizou-se um estudo qualitativo, com recurso à entrevista semiestruturada, tendo participado 12 professores. O conteúdo resultante da transcrição das entrevistas, foi analisado recorrendo à análise do conteúdo. Foi possível concluir que: (1) a totalidade dos participantes manifestou-se favorável à existência de um sistema de avaliação; (2) os principais problemas apontados aos processos de avaliação são a burocracia e o facto de ser feita por pares, o que pode condicionar a isenção e o rigor; (3) as sugestões dadas pelos participantes apontam para a necessidade de a avaliação ser efectuada por equipas com ligação às faculdades, pelo coordenador de departamento e o órgão de gestão da escola, o diretor da escola, por observadores externos, ou ainda por professores com formação.
- Aerobic fitness as an important moderator risk factor for loneliness in physically trained older people: an explanatory case study using machine learningPublication . Encarnação, Samuel Gonçalves; Vaz, Paula Marisa Fortunato; Fortunato, Álvaro; Forte, Pedro; Vaz, Cátia; Monteiro, A.M.Loneliness in older people seems to have emerged as an increasingly prevalent social problem. Objective: To apply a machine learning (ML) algorithm to the task of understanding the influence of sociodemographic variables, physical fitness, physical activity levels (PAL), and sedentary behavior (SB) on the loneliness feelings of physically trained older people. Materials and Methods: The UCLA loneliness scale was used to evaluate loneliness, the Functional Fitness Test Battery was used to evaluate the correlation of sociodemographic variables, physical fitness, PAL, and SB in the loneliness feelings scores of 23 trained older people (19 women and 3 men). For this purpose, a naive Bayes ML algorithm was applied. Results: After analysis, we inferred that aerobic fitness (AF), hand grip strength (HG), and upper limb strength (ULS) comprised the most relevant variables panel to cause high participant loneliness with 100% accuracy and F-1 score. Conclusions: The naive Bayes algorithm with leave-one-out cross-validation (LOOCV) predicted loneliness in trained older with a high precision. In addition, AF was the most potent variable in reducing loneliness risk.
- Physical fitness, but not specific skill levels nor motor coordination, is associated with coaches’ perception of young soccer players competencePublication . Lopes, Vitor P.; Fortunato, Álvaro; Gonçalves, Celina; Rodrigues, Luis PauloMany youth sports programs in sport clubs aim to delop sporting excellence and focus on results, with the tengible success of a sports program often related to the club's ability to produce good athletes within specific sporting disciplines.
