- 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.
- 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.
- 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.
- Variations in locomotor intensities across soccer match halves concerning player sectorial positionsPublication . Gouveia, Élvio Rubio; França, Cíntia; Henriques, Ricardo; Santos, Francisco; Mâncio, Rui; Przednowek, Krzysztof; Sarmento, Hugo; Gouveia, Élvio Rúbio; França, Cíntia; Baeta Santos, Francisco José; Sarmento, HugoPurposeThis study aims to explore disparities in locomotor metrics such as total distance (TD), high-speed running (HSR), accelerations (Acc), decelerations (Dec), and maximum speed (MS) across five soccer positions – centre defenders, fullbacks, midfielders, wingers, and forwards – during the 1-, 3-, and 5-minute match intensity periods (MIP). Additionally, it seeks to assess the difference in those locomotor metrics between the first and second halves of the match.MethodsAn observational, retrospective cohort study was undertaken with a professional team covering 32 official matches. A total of 20 soccer players participated in this study. Data were collected using a 10-Hz GNSS unit (Apex pro series, StatSports, Northern Ireland). The MIP considered different time durations (1, 3, 5 min in the 1st and the 2nd halves).ResultsSoccer players exhibited position-specific differences in locomotion, with Wingers covering the most distance and forwards showing the highest Acc and Dec. HSR was most notable in the fullbacks. The second half saw varied changes, with midfielders increasing in distance covered. ANCOVA revealed significant positional differences in TD during longer MIPs and between match halves. HSR varied across positions but only differed between halves in the 5-minute MIP. Acc and Dec displayed half-time differences, while maximal speed was consistently higher in the second half.ConclusionsThis study highlights the impact of player position and matches progression on locomotor metrics in soccer, underscoring the need for customised training and strategic adaptability to maximise performance throughout the game.
