- Differential Patterns in Motivations for Practicing Sport and Their Effects on Physical Activity Engagement across the LifespanPublication . Nascimento, Marcelo de Maio; Gouveia, Élvio Rúbio; Gouveia, Bruna R.; Marques, Adilson; França, Cíntia; Campos, Pedro; Martins, Francisco; Garcia-Mayor, Jesús; Ihle, AndreasThis study aims to report what motivates individuals to be physically active, to determine whether motivating factors influence physical activity (PA) levels, and whether this differs across the lifespan. This is a cross-sectional study with 498 individuals: 117 adolescents, 306 adults, and 75 older adults. PA was assessed using Baecke’s questionnaire, and motivating factors for practicing sports were investigated using a scale with twelve questions. The factor analysis identified three motivating factors for sports practice: psychosocial, bodily, and well-being. The scale’s overall reliability and internal consistency indicated a Cronbach’s alpha of 0.885. The analysis of covariance (ANCOVA) adjusted for sex indicated the three factors as having a significant effect on PA (p < 0.050); however, only the well-being factor showed a significant interaction with age groups (p = 0.023, ηp2 = 0.030). Subsequently, the effect of the well-being factor on PA scores in each age group was explored through regression analyses. Only older adults showed a significant association in the unadjusted [OR = 0.378, p = 0.001, R2 = 0.243] and the sex-adjusted analysis [OR = 0.377, p = 0.001, R2 = 0.288]. These results help us to better understand the underlying motivational reasons in different age groups for engaging in sports.
- Dimensional stability of a preliminary vinyl polysiloxane impression materialPublication . Martins, Francisco; Reis, José; Navarro, Ignacio Barbero; Maurício, PauloOral rehabilitation success depends upon the accuracy and dimensional stability of the impressions. The purpose of this study is to evaluate the dimensional changes of a first impression type VPS (Vinyl Polysiloxane) (Imprint™ 4 Preliminary Penta™ Super Quick, 3M ESPE™, St Paul, MN, USA). 10 samples were obtained from this silicone with an automatic mixing machine (Pentamix 2, 3M ESPE™, Seefeld, Germany) according to International Organization for Standardization (ISO) 4823:2000 and stored in the IPQ (Portuguese Institute for Quality) for one week. The measurements were performed by laser interferometry, according to the Michelson technique. The dimensional stability was calculated according to the formula specified in ISO (International Organization for Standardization) 4823:2000. A statistical analysis via a one-way repeated measures ANOVA was performed. The material shrinkage was 0.29 ± 0.15% after setting, 0.32 ± 0.21% at 24 h and 0.30 ± 0.23% after 1 week. No significant shrinkage of the silicone under investigation was found over time. This material can be stored for a week without the risk of clinically significant dimensional changes.

- Emerging Technologies to Promote Fans Interaction in Football Events: A Systematic ReviewPublication . Martins, Francisco; França, Cíntia; Paixão, Pedro; Martinho, Diogo V.; Campos, Pedro; Gouveia, Bruna R.; Lopes, Hélder; Ihle, Andreas; Marques, Eduardo; Gouveia, Élvio Rúbio; Gouveia, BrunaAs the digital revolution continues to take hold in contemporary society, new technology and communications networks have provided football with new possibilities and prospects for expansion. This study provides an assessment of the published research regarding innovative digital tools designed to increase the interactivity of fans when watching a football match, regardless of whether they do it at home or at the stadium. A systematic review of the literature was performed, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The search was conducted in the PubMed, Web of Science, and Scopus databases. The final sample included eleven studies for analysis. Overall, the investigations that structure this review seem to be in the early stages of their development, with eight of them making tests with the target audience and the other three still in protocol development processes. Six studies concluded that fans had positive and exciting experiences using mobile applications or interactive systems. Two studies showed promising results in the area of football fans’ health, and only one study showed some difficulties for fans using an ad hoc network in the stadium. Adding personal information, fan interaction systems, specific information about the players and the teams’ tactical strategies, and interactive fan voting seem to be important elements for designing a successful interactive tool that contributes to increasing fans’ enthusiasm during football matches.

- Quantitative Sensory Testing: Fiabilidade teste-reteste, erro padrão de medida e diferença mínima detetável de um protocolo de avaliação lombar em adultos saudáveisPublication . Martins, Francisco; Pires, DiogoIntrodução: O Quantitative Sensory Testing (QST) é um método de avaliação quantitativa da função do sistema somatossensorial, que permite identificar potenciais mecanismos neurofisiológicos subjacentes à experiência de dor do individuo, possibilitando uma abordagem mais personalizada nos programas de reabilitação. No entanto, ainda persiste a carência de dados e garantias da fiabilidade deste instrumento em indivíduos saudáveis. Assim, estabelecer dados acerca da fiabilidade do QST, contribuirá para a melhor interpretação dos valores das medições em indivíduos saudáveis, a sua reprodutibilidade e utilização como referência em futuros estudos e prática clínica. Objetivo: Avaliar a fiabilidade teste-reteste, erro padrão de medida (EPM) e diferença mínima detetável (DMD) deste instrumento em indivíduos saudáveis. Métodos: Um protocolo de avaliação do QST para a região lombar foi avaliado com 1 semana de diferença em 14 indivíduos saudáveis. Todas as medições foram efetuadas pelo mesmo investigador. Para analisar a fiabilidade e a concordância do QST, foram calculados os coeficientes de correlação intraclasse (ICC) e respetivos 95% intervalos de confiança, os diagramas Bland-Altman e os 95% limites de concordância (LDC), e os valores absolutos e de percentagem em relação à média do erro padrão de medida (EPM) e diferença mínima detetável (DMD). Resultados: Obtiveram-se resultados para a fiabilidade teste-reteste moderados a excelentes (ICC>0.6), exceto nos parâmetros de deteção térmicos onde foi baixa (ICC<0.5) e com pequenos limites de concordância. Os valores de EPM obtidos para todos os parâmetros térmicos foram inferiores a 3ºC, e para o PPT variou de 21.16Kpa a 56.54Kpa. Os valores de DMD para o parâmetro mecânico, PPT, apresentaram valores superiores a 130Kpa na região lombar e pé. Uma grande variabilidade de valores de %EPM e %DMD foi encontrada, com valores entre de 0.51% a 20.33, e 1.42% e 56.34%, respetivamente. Conclusão: Este estudo contribuiu para estabelecer valores de fiabilidade intra avaliador do QST, e definir intervalos associados à magnitude do erro, para 6 parâmetros de um protocolo de avaliação lombar. Os valores para esta bateria de teste mostraram-se aceitáveis, persistindo ainda algumas dúvidas nos parâmetros de deteção térmica. Estes achados ajudam a estabelecer uma base para utilização do QST em contexto de investigação e avaliação de outcomes na prática clínica.
- Virtual Reality Gaming in Rehabilitation after Musculoskeletal Injury—User Experience Pilot StudyPublication . Gouveia, Bruna R.; Gouveia, Élvio Rúbio; Campos, Pedro; França, Cristiano S.; Rodrigues, Louis M.; Martins, Francisco; França, Cíntia; Gonçalves, Frederica; Teixeira, Fernando; Ihle, AndreasThe purposes of this study were twofold: (1) to describe a new technological solution for the rehabilitation of musculoskeletal injuries based on virtual reality (VR) gaming, and (2) to analyze the variation in rated perceived exertion (RPE) and heart rate (HR) of the participants when undergoing a rehabilitation session based on different VR games. Thirty-seven participants aged 23.7 ± 7.0 years tested during five customized VR games to provide a complete rehabilitation session after a musculoskeletal injury. The results of the Friedman test indicated a statistically significant difference in RPE scale and HR across the five VR games throughout a complete rehabilitation session (χ2 (4, n = 35) = 75.59; p < 0.001 and χ2 (4, n = 35) = 27.75, p < 0.001, respectively). RPE and HR increased significantly from Game 1 to Game 2 (z = −5.16, p < 0.001), from Game 1 to Game 3 (z = −5.05, p < 0.001), from Game 1 to Game 4 (z = −4.87, p < 0.001), and from Game 1 to Game 5 (z = −3.61, p < 0.001). Moreover, the results showed a high perceived usability of the system, greater intrinsic motivation to perform the rehabilitation exercises, a high level of immersion, and a good experience in the VR gaming environment. Our study stimulates extended intervention programs following-up on this immersive virtual reality rehabilitation system to support soccer players recovering from musculoskeletal injuries.
