- Caracterização das lesões numa equipa do futebol profissional portuguêsPublication . Martins, Francisco; Santos, Francisco; Caldeira, Romualdo; Henriques, Ricardo; França, Cíntia; Ornelas, Rui; Gouveia, Élvio RúbioO futebol profissional caracteriza-se pelas suas exigências físicas, fazendo com que a exposição dos jogadores a riscos elevados de lesão seja uma problemática em ascensão. O objetivo deste estudo é caracterizar as lesões de uma equipa profissional de futebol ao longo de uma época. Trinta e seis atletas do sexo masculino, enquadrados na 1.ª Liga Portuguesa de Futebol, foram acompanhados ao longo da época desportiva 2020/2021. Caracterizou-se uma lesão desportiva como a incapacidade demonstrada pelo atleta, devido a um momento de treino ou jogo, que exigiu intervenção médica ou interrupção parcial ou total da sua atividade desportiva. No total, 34 lesões foram registadas. Cada jogador falhou em média 14.3 dias devido a lesão. As lesões mais recorrentes foram as entorses (35.3%) e as lesões musculares (35.3%), sendo os membros inferiores a zona do corpo mais afetada (85.29%). As lesões ocorreram maioritariamente em treino (58.8%) e as de jogo registaram-se sobretudo nos últimos 15 minutos (57.14%). Os resultados obtidos neste estudo vêm auxiliar o staff técnico das equipas profissionais de futebol na identificação de fatores de risco associados às lesões no futebol profissional. O estudo desta temática é fundamental para a otimização dos protocolos de prevenção e de recuperação de lesões.
- Diferenças do perfil físico e aptidão funcional entre jogadores de futebol e futsalPublication . Santos, João; Santos, Francisco; Baeta Santos, Francisco José; Rúbio, Élvio; Gouveia, Élvio Rúbio; Gouveia, Elvio Rúbio; Gouveia, Elvio RúbioO Futsal e o Futebol são dois desportos praticados a um ritmo elevado (Kartal, R. 2016). A evidência científica sugere que no futebol a intensidade média varia entre 80-90% da FCmáx e o VO2máx entre 50-75 ml·kg-1·min-1, no futsal a intensidade média varia entre 85-90% da FCmáx e os valores de VO2máx entre 50-55 ml·kg-1·min-1 (Leite, 2016). A intensidade de um jogo de futsal é mais elevada do que um jogo de futebol, tornando-se indispensável uma elevada capacidade anaeróbia e uma maior presença da força muscular (Vaeyens, Lenoir, Williams, & Philippaerts, 2007). O presente estudo passou por analisar as diferenças ao nível do perfil físico e aptidão funcional entre os jogadores destas modalidades nos parâmetros da composição corporal, força muscular, resistência aeróbia e equilíbrio. A amostra foi composta por 14 jogadores (21.8 anos, 174.2cm, 70.8kg) de futsal e 24 jogadores (20.7 anos, 173.5cm, 73.3kg) de futebol da equipa B do Club Sport Marítimo, durante a época 2022-2023. Os praticantes foram avaliados nas variáveis da composição corporal da composição corporal (Inbody 770), força muscular dos embros inferiores (Isocinético Biodex System Pro 4), força explosiva dos membros inferiores (Optojump Next), flexibilidade (teste do Sit and Reach), equilíbrio (Biodex Balance System) e resistência cardiorrespiratória (COSMED K5). Em termos de resultados, foram verificadas diferenças significativas ao nível da flexibilidade, força muscular máxima, força explosiva dos membros inferiores e somente numa das variáveis da composição corporal, nomeadamente o conteúdo de água intracelular. Em todos os parâmetros mencionados, os jogadores de futebol apresentaram valores mais elevados comparativamente aos de futsal. Por outro lado, não foram verificas diferenças significativas na aptidão cardiorrespiratória nem no equilíbrio. Através do presente estudo é possível concluir que apesar de todas as semelhanças existentes entre a modalidade de futebol e futsal, existem realmente algumas diferenças relativamente ao perfil físico dos seus praticantes.
- Digital health in schools: a systematic reviewPublication . França, Cíntia; Santos, Francisco; Martins, Francisco; Lopes, Helder; Gouveia, Bruna; Gonçalves, Frederica; Campos, Pedro; Marques, Adilson; Ihle, Andreas; Gonçalves, Tatiana; Gouveia, Élvio RúbioWorldwide, the growing digitalization process and increase in smartphone usage have contributed to promoting mobile health (mHealth) services. This study provides an overview of the research targeting the effectiveness of mHealth interventions among children and adolescents in the school environment. A systematic literature review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in the PubMed, Web of Science, and Scopus databases. The results show that physical activity and nutrition are the main intervention topics. Health literacy, mental health, productive health, vaccination rates, and social interaction were also considered in mHealth interventions. Of the 13 studies that remained for analysis, 12 described positive outcomes in at least one health variable after using an mHealth tool. Overall, interventions ranged between four and 24 weeks. Only seven studies managed to have at least 80% of the participants from the baseline until completion. Adding personal information, user interaction, and self-reference comparisons of performance seems crucial for designing successful health digital tools for school-aged children and adolescents.
- Efeitos do destreino de curto prazo na composição corporal, força, potência e capacidade anaeróbica de jogadores de futebolPublication . Saldanha, João; Santos, Francisco; Baeta Santos, Francisco José; Gouveia, Élvio R.; Gouveia, Élvio Rúbio; Gouveia, Elvio Rúbio; Gouveia, Elvio RúbioResumo O destreino pode ser definido como uma redução parcial ou interrupção total das cargas de treino, levando a uma série de adaptações físicas e fisiológicas. Estudos anteriores evidenciaram reduções significativas no desempenho de força e potência em atletas com diferentes antecedentes de treino após uma pausa de longo prazo (ou seja, períodos superiores a 4 semanas). Por outro lado, relativamente ao destreino de curto prazo (ou seja, <4 semanas), o nível de evidência é limitado. Portanto, até ao momento, não existe consenso acerca dos efeitos das interrupções de curto-prazo no decorrer da época, o que representa uma limitação da pesquisa atual na modalidade do Futebol. O objetivo do estudo é analisar os efeitos de uma paragem de 5 dias nas qualidades físicas de jogadores de futebol, em que os participantes foram avaliados em dois momentos, pré e pós interrupção, no que diz respeito à sua Composição Corporal, Força Máxima de Abdução e Adução da Coxa, Potência Muscular (Saltos Verticais) e Capacidade de Sprints Repetidos (Teste ‘RAST’). Verificaram-se diferenças significativas apenas na Capacidade de Sprints Repetidos, tendo o desempenho geral da equipa piorado, no tempo total de execução, na potência pico e na velocidade máxima atingida no teste ‘RAST’. As restantes avaliações parecem não ter sofrido alterações relevantes após o período de paragem. Uma compreensão mais profunda desta questão é fundamental para os treinadores e cientistas do desporto envolvidos no planeamento e operacionalização diária de sessões de treino, a fim de ajudar a selecionar e a sequenciar, de uma forma mais adequada, o conteúdo e intensidade do treino ao longo da época competitiva.
- Emerging technologies to promote fans interaction in football events: a systematic reviewPublication . Martins, Francisco; França, Cíntia; Santos, Francisco; Martinho, Diogo; Saldanha, Carolina; Gouveia, Élvio RúbioReview question / Objective: The search terms used for this review were constructed using the PICOS framework: (1) population were people in general of both genders and any age, (2) studies based on digital technologies used in football sportive events, (3) comparisons made in the domains of motivation, interaction, satisfaction and interest, (4) data reporting the use of digital tools (studies with no results reported will be considered, besides not having outcomes), (5) Intervention studies with a pre and post-test design, descriptive studies, theorical studies, and protocol proposals, and (6) articles written in English, Spanish or Portuguese. Condition being studied: Our concern is with the acceptance of the fans returning to the stadium with normality after a pandemic period. In addition, we also want to understand what kind of interactive applications are already on the market or with their well defined protocols that intend to increase fan interaction at live games, increasing their motivation to go to the stadium and to have accurate and updated live information.
- Estimated energy expenditure in youth while playing active video games: a systematic reviewPublication . França, Cíntia; Ashraf, Sadaf; Santos, Francisco; Dionísio, Mara; Ihle, Andreas; Marques, Adilson; Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; França, Cíntia; Dionisio, Mara; Marques, Adilson; de Maio Nascimento, Marcelo; Gouveia, Élvio Rúbio; Baeta Santos, Francisco JoséSedentary behavior and inadequate energy expenditure are serious global public health concerns among youngsters. The exponential growth in technology emerges as a valuable opportunity to foster physical activity, particularly through active video games. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in PubMed, Web of Science, Cochrane, and Scopus to provide a comprehensive view of the literature on energy expenditure levels among adolescents while playing active video games. Among the 574 manuscripts identified at the first screening stage, 23 were retained for analysis. Ten studies were characterized by longitudinal and thirteen by cross-sectional designs. The results showed that short-term active video games elicited energy expenditure values comparable to moderate-intensity physical activity (3–6 METs). However, in intervention programs (with at least six weeks) the results indicate no significant effects of active video games on youngsters’ energy expenditure levels and physical activity profiles between baseline and follow-up assessments. Overall, active video games based on sports and dance were the most used, and boys tended to achieve higher energy expenditure than girls. The diversity of methods implemented limits comparing results and drawing generalized conclusions. However, considering its attractiveness to youth, active video games might emerge as a complementary tool to traditional physical activities promoted in schools and local communities. Details regarding gender differences and contradictory results of longitudinal approaches should be considered in future research based on standardized methods.
- Monitoring body composition and physical fitness of elite female basketball players after 16 weeks of in-season trainingPublication . França, Cíntia; França, Ana; Marques, Adilson; Ihle, Andreas; Lopes, Helder; Santos, Francisco; Gouveia, Élvio R.Understanding the physiological changes in players’ profiles during the season is crucial to optimize training prescription according to players’ needs towards a high-level game performance. The purpose of this study was to assess the variation in body composition and physical fitness of elite female basketball players after 16 weeks of in season training. The sample was composed of 13 elite female basketball players aged 19.7 ± 4.3 years (height: 173.7 ± 9.8 cm, body mass: 70.4 ± 11.3 kg). Body composition, static strength, lower-body explosive strength, speed, agility, and aerobic endurance, were assessed initially (T1) and 16 weeks after the regular season (T2). Significant improvements were found between T1 and T2 for the squat jump (t = -2.433, p ≤ 0.05, d = -0.39), the 20 m linear sprint (t = 2.493, p ≤ 0.05, d = 0.87), and the Yo-Yo Intermittent Endurance Test-Level 2 (t = -3.746, p ≤ 0.01, d = - 0.34). Lower-body explosive strength showed a significant contribution to agility and speed. The visceral fat area presented a greater negative correlation with the aerobic and anaerobic capacity. Sports practitioners and coaches should be aware of the importance of monitoring players’ body composition and physical fitness to assess the physiological responses to the training process and to optimize training prescription. Training contents may be adjusted according to the responses recorded to achieve the defined goals. The positive contribution of lower-body explosive strength to speed and agility, emphasizes the need to include in-season strength programs targeted to enhance players’ overall physical fitness.
- School-Based Family-Oriented Health Interventions to Promote Physical Activity in Children and Adolescents: A Systematic ReviewPublication . Santos, Francisco; Sousa, Honorato; Gouveia, Élvio Rúbio; Lopes, Helder; Peralta, Miguel; Martins, João; Murawska-Ciałowicz, Eugenia; Zurek, Grzegorz; Marques, AdilsonObjective: This study aimed to systematically review and analyse intervention programs in a school context centred on the family, focused on increasing youths’ physical activity. Data source: The research was carried out in the PubMed, Scopus and Web of Science databases. Study inclusion criteria: Studies were included if participants were children or adolescents, focusing on school-based intervention studies with parental involvement and physical activity, sedentary behaviour or physical fitness outcomes. Data extraction: The search was performed according to the PRISMA protocol. A total of 416 articles were identified. After being considered for eligibility and duplicates, 22 studies were identified as relevant for inclusion. Data synthesis: Sample and intervention characteristics, objective, the role of the family, outcomes measures, main findings regarding the outcomes and risk of bias. Results: Ten studies reported improvements in physical activity, 6 in sedentary behaviour and 9 in the components of physical fitness and/or skills related to healthy behaviours and lifestyles. Most of the interventions adopted a multidisciplinary and multi component approach. Conclusions: Most interventions employed a school’s multidisciplinary/multi-component approach to promoting physical activity, nutrition, and general education for healthier lifestyle behaviours. The impact of school-based interventions involving families on youth’s physical activity levels is still a relatively emerging theme. Further research is needed given the diversity of the intervention’s characteristics and the disparity in the results’ efficacy.

- Sex differences in body composition and physical fitness of young basketball playersPublication . França, Cíntia; Martins, Francisco; Santos, Francisco; Teixeira, Francisco; Śliż, Maciej; Przednowek, Krzysztof; Lopes, Helder; Gouveia, Élvio R.; Pestana Martins, João Francisco; Baeta Santos, Francisco José; Lopes, Helder; Gouveia, Elvio RúbioIntroduction: Throughout adolescence, sex differences are observed for anthropometric, body composition, and physical fitness variables. Objective: This study’s aims were: (1) to explore differences in anthropometry, body composition, and physical fitness performance between male and female youth basketball players, and (2) to examine the relationships between body composition, strength, and balance performance. Methodology: Forty-nine regional youth basketball players (27 males; mean age = 14.3 ± 1.2 years), were assessed for body composition, strength, speed, upper-limb coordination, and balance performance. Results: As expected, males were taller (p = 0.002), with lower body fat (p < 0.001) and increased fat-free mass (p < 0.002) than females. Body fat correlated significantly with strength (handgrip: rs = -0.47, p < 0.001; countermovement jump: rs = -0.72, p < 0.001; squat jump: rs = -0.73, p < 0.001; horizontal jump: rs = -0.76, p < 0.001), upper-limb speed and coordination (rs =-0.32, p = 0.027), and 20-m sprint performance (rs = 0.72, p < 0.001), but not with balance tasks. Body mass and fat-free mass were negatively associated with balance, indicating reduced postural control. Conclusions: These findings underscore the importance of accounting for sex differences when developing training programs for youth basketball players. Also, coaches and their staff should monitor body composition, particularly body fat, to enhance explosive strength and speed. Fat-free mass positively influences balance ability, highlighting the role of body composition in physical fitness.
