- Associação entre a relação 2D:4D e o desempenho desportivo em atletas. Uma revisão sistemática e meta-análisePublication . Bernardino, Vanda; Rebelo, André; Cruz, João; Vaz, Vasco; Santos, João Valente dos; Silva, Manuel J. Coelho; Duarte-Mendes, PedroIntrodução: A identificação de jovens atletas talentosos no desporto de alto rendimento requer uma abordagem multidisciplinar que considere a complexa cominação de características genéticas, psicológicas, físicas, técnicas e táticas, sendo o rácio 2D:4D uma possível ferramenta adicional. Objetivo: Este estudo visa analisar, através de uma revisão sistemática e meta-análise, as relações entre o rácio 2D:4D e várias capacidades físicas em atletas de diferentes idades e níveis competitivos. Metodologia: A pesquisa bibliográfica foi realizada nas bases de dados PubMed, Scopus, Web of Science e SPORTDiscus, com os artigos recuperados sendo importados para o software Cadima para otimizar a síntese de evidências e garantir rigor metodológico. A qualidade dos estudos foi avaliada utilizando a lista de “Downs e Black”, e a análise estatística da meta-análise foi efetuada com o modelo de Efeitos Aleatórios para considerar a variabilidade entre os estudos. Resultados: Foram selecionados 67 estudos para a revisão da literatura, e 19 estudos, que avaliaram 3581 rácios 2D:4D, foram incluídos na meta-análise. Os principais resultados revelaram diferenças significativas entre homens e mulheres, com os homens apresentando valores de 2D:4D tipicamente mais baixos. Além disso, os atletas tendem a ter rácios 2D:4D inferiores em comparação com os não-atletas. Conclusões: Foram identificadas associações negativas entre o rácio 2D:4D e a capacidade aeróbia, VO2máx, potência anaeróbia e força muscular, enquanto que as relações com velocidade, capacidade anaeróbia e flexibilidade mostraram-se menos consistentes.
- Behavior change wheel as a tool to promote physical activity in online intervention: a case studyPublication . Couto, Nuno; Morgado, Vitor; Pereira, Tomás; Vitorino, Anabela; Bento, Teresa; Alves, Susana; Cid, Luís; Duarte-Mendes, PedroIntroduction: Physical activity (PA) has significant health benefits. However, one in four adults does not meet the globally recommended levels of PA. Considering that PA behavior is influenced by various factors operating at multiple levels, including personal, social, and environmental factors, a singlesubject behavioral change intervention was developed to promote PA behavior through online sessions. Method: Based on a one-to-one intervention, the Behavior Change Wheel (BCW) methodology was used to design an intervention that was developed for 24 weeks, including eight weeks of online sessions and 16 weeks of follow-up. Results: We observed an increase of metabolic equivalent (MET-min/week; baseline = 2,970; eight weeks = 6,440; 24 weeks = 6,744) and daily steps (baseline = 8,372; eight weeks = 10,234; 24 weeks = 12,142), which provides some evidence for the efficacy of online methodologies, especially in the relation one-to-one. Conclusion: The intervention, designed through BCW, had a positive effect in promoting more PA in a subject of our case study and provided evidence that can be used in further interventions that aim to increase PA levels in the population; however, future studies must be conducted to expand the evidence in other domains.
- Body composition, strength and muscle power indices at the different competitive levels of FutsalPublication . Rebelo, Miguel; Marques, Catarina; Crisóstomo, Rute; Silva Batista, Marco Alexandre; Paulo, Rui; Duarte-Mendes, Pedro; HONÓRIO, SAMUEL; Serrano, JoãoObjective: The aim was to verify the differences in physical condition (body composition, power and muscle strength) in futsal players from three competitive levels. Methodology: Sixty-eight (24.26 ± 4.63 years old) Portuguese futsal players participated in the study, divided into: elite, sub-elite and amateur. We used the bioimpedance, the countermovement jump and the isokinetic dynamometer to assess physical condition, and the Kruskal-Wallis test to compare variables between groups. Results: There were no differences in body composition between groups. Elite players had higher countermovement jump heights than amateur players (p < 0.001). There were significant differences in the isokinetic muscle strength of the knee flexors, with the elite players showing more strength than the amateur players (p = 0.047). Discussion: The results of the research should be contrasted with those of other research found in the literature. Conclusions: The elite players had higher physical condition parameters (more lower limb power and more flexor muscle strength) compared to the amateur players. We would point out that all groups had a high probability of lower limb muscle injury (H/Q ratio < 60%) at this stage of the sports season, alerting training professionals to the importance of individualised physical condition analysis.
- Bridging the gap between training and competition in elite rink hockey : a pilot studyPublication . Ferraz, António; Pérez-Chao, Enrique Alonso; Ribeiro, João; Spyrou, Konstantinos; Freitas, Tomás T; Santos, João Valentes dos; Alcaraz, Pedro E; Travassos, Bruno; Duarte-Mendes, PedroBackground: Monitoring training load and competition load is crucial for evaluating and improving athlete performance. This study proposes an applied approach to characterize and classify the training task specificity in relation to competition in a top-level rink hockey team, considering external and internal load from training tasks and competition. Hypothesis: Training tasks and game demands have significant dose-response differences, and exercises can be classified successfully based on their physiological and biomechanical demands. Study Design: Cross-sectional study. Level of Evidence: Level 5. Methods: Ten elite-level male rink hockey players participated in this study. Players were monitored on 6 different task categories during 8 training sessions and 2 official games. A linear mixed model with random intercepts was used to compare training tasks and competition load, accounting for individual repeated measures. A 2-step cluster analysis was performed to classify the training tasks and games based on physiological and biomechanical load, employing log-likelihood as the distance measure and Schwartz’s Bayesian criterion. Results: Average heartrate , maximum heartrate, and high-speed skating (18.1-30 km/h) were the best physiological load predictors, while the most effective biomechanical load predictors were impacts [8-10] g(n), decelerations [-10 to -3]m/s²(n), and accelerations [3-10]m/s²(n). Different physiological and biomechanical responses were verified between training tasks and match demands. A 4-quadrant efforts assessment for each task category revealed that training tasks used by the team in the analysis presented lower biomechanical and physiological load demands than competition. Conclusion: Training tasks failed to adequately replicate the specific demands of competition, especially regarding high mechanical stress, such as the absence of high-intensity impacts and decelerations. Clinical Relevance: This method of classification of training tasks may allow coaches to understand further the specificity and contribution of each task to competition demands, consequently improving the capacity of load management and the preparedness and readiness of players for competition.
- The effect of smoking on lung function changes during a 16-week combined exercise program in middle-aged workers: a latent growth curve analysisPublication . Silva, Fernanda M.; Ferreira, José P.; Teixeira, Ana M.; Monteiro, Diogo; Duarte-Mendes, Pedro; Silva, Fernanda M.Purpose To investigate the longitudinal changes in lung function of sedentary middle-aged workers over a 16-week combined exercise training program. Methods Thirty-six sedentary workers (53.70 ± 6.92 years old) were randomly allocated to either a combined aerobic and resistance training program (n = 18) or a control group (n = 18). Lung function was evaluated through spirometry using a portable flow spirometer (Spiropalm 6MWT, Cosmed, Italy). Predicted percentages of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC ratio, and mean forced expiratory flow between 25 and 75% of exhaled FVC (FEF25–75) were analyzed. Assessments were performed at baseline (M1), after 8-week (M2) and 16-week follow-up (M3). The changes in lung function were analyzed using the Latent Growth Curve Modeling that estimated interindividual and intraindividual growth paths. Results Smoking status revealed a significant effect on lung function growth with significant paths to intercept and slope for all models in both groups. The exercise group participants who are non-smokers revealed higher increases in FVC% (β = .22), FEV1% (β = .08), FEV1/FVC% ratio (β = .19), and FEF25–75% (β = .06) compared to those who are smokers from M1 to M3. The control group revealed a lower growth in lung function from M1 to M3, with a lower slope observed in smokers compared to non-smokers for FVC% (β= − .44), FEV1% (β = −.41), FEV1/FVC% (β = − .98), and FEF25–75% (β = − .52). Conclusion Our findings suggest that a 16-week combined training program is an effective strategy to improve lung function among sedentary workers, with a higher magnitude of improvement for non-smokers compared to smokers.
- Effects of a land and aquatic exercise-based program on pain, mobility and quality of life in patients with chronic low back pain: a study protocol for a randomized controlled trialPublication . Borges, Joana; Monteiro, Diogo; Silva, Fernanda M.; Jacinto, Miguel; Pastilha, Tiago; Duarte-Mendes, PedroBackground Chronic low back pain (CLBP) is a disease with significant functional, emotional and social impact. Several interventions are proposed for its management and exercise is one of main, land-based or water-based. This study describes a randomized controlled trial that will analyze the effect of a combined aquatic and land-based exercise program compared to an aquatic-based program on pain, functional incapacity and quality of life in adults with CLBP. Additionally, it will analyze the effects of exercise cessation in the same outcomes. Methods and design A blind randomized controlled trial will be developed with a 1:1 allocation ratio. Around 30 adults with mechanical CLBP will be randomly allocated in two groups. The experimental group (ALG) will complete an aquatic and land-based exercise program and control group (AG) will carry out only an aquatic program, both for 8 weeks. Participants will be assessed with Visual Analogue Scale, Oswestry Disability Index, Short-Form 36, Tampa Scale of Kinesiophobia-13 and Modified-Modified Schober Test, collected at baseline (M0), after 8 weeks (M1) and 4 weeks after the end of the intervention (M2). Discussion This study may provide a relevant contribution to understand the potential effect of a combined land and aquatic exercise program on pain, functional disability, fear of movement, quality of life and lumbar mobility. The results may provide important information for CLBP management.
- Grip strength, fall efficacy, and balance confidence as associated factors with fall risk in middle-aged and older adults living in the communityPublication . Marconcin, Priscila; Martinho, Estela; Serpa, Joana; Nascimento, Marcelo; Flôres, Fábio; Santos, Vanessa; Loureiro, Vânia; HONÓRIO, SAMUEL; Marconcin, PriscilaBackground: Falls are a major public health concern among older adults, often resulting in injury, functional decline, and reduced quality of life. While handgrip strength (HGS), fall efficacy, and balance confidence have individually been associated with fall risk, their com bined predictive value is still underexplored, particularly in physically active older adults. This study aimed to investigate the relationship between HGS, fall efficacy, and balance confidence and their association with fall risk in community-dwelling older adults engaged in regular exercise programs; A cross-sectional study was conducted with 280 participants aged 55 and over from community exercise programs near Lisbon, Portugal. Fall risk was assessed through self-reported falls in the past 12 months. HGS was measured with a dynamometer, fall efficacy using the Falls Efficacy Scale-International (FES-I), and balance confidence using the Activities-specific Balance Confidence (ABC) Scale. Statistical anal yses included Spearman correlations and binary logistic regression. Results: Falls were reported by 26.4% of participants. Fall efficacy and balance confidence were significantly associated with fall history, while HGS was not. Fall efficacy was significantly associated with increased fall risk, as indicated by the odds ratio (OR = 3.37, p < 0.001), while balance confidence was negatively associated (OR = 0.95, p < 0.001). HGS was positively correlated with balance and confidence but not with fall incidence. Conclusions: Psychological factors, particularly fall efficacy and balance confidence, play a critical role in fall risk among physi cally active older adults. However, this study included physically active middle-aged and older adults living in the community, which should be considered when interpreting the generalizability of the results. These findings support the integration of simple, validated psychological assessments into fall prevention strategies in community settings.
- Impact of muscle mass and muscle strength on quality of life of individuals with intellectual and developmental disabilitiesPublication . Jacinto, Miguel ; Monteiro, Diogo ; Couto, Nuno ; Diz, Susana ; Matos, Rui ; Amaro, Nuno; Antunes, Raul ; Duarte-Mendes, PedroThis study aimed to investigate the relationship between muscle strength and perceived quality of life in individuals with Intellectual and Developmental Disabilities (IDDs). A cross-sectional study was carried out, which involved 37 participants with a mean age of 39.08 years (SD = 0.05), ranging from 20 to 58 years. The participants were assessed on anthropometric and body composition parameters, a 30 s chair stand test and isokinetic dynamometry. Quality of life was assessed using the Portuguese version of the Personal Outcomes Scale. Pearson’s correlation analyses were carried out to examine the associations between strength measures and quality of life. Significant correlations were observed between strength measures and quality of life. In addition, lower limb muscle strength, particularly in flexion (left: r = 0.450; p ≤ 0.001; right: r = 0.504; p ≤ 0.001) and extension (r = 0.328; p = 0.05), showed positive correlations with quality of life. These findings provide preliminary evidence suggesting that muscle mass and strength may serve as potential predictors of quality of life in individuals with IDD.
- Lesões no boxe em Portugal: análise da incidência, mecanismos, fatores de risco e medidas de prevenção de lesõesPublication . SottoMayor, Ricardo; Monteiro, Diogo; Alexandre, Élio; Jacinto, Miguel; Silva, Fernanda M.; Flores, Gonçalo; Travassos, Bruno; Duarte-Mendes, PedroIntrodução: A modalidade do boxe está associada a uma elevada taxa de lesões e traumatismos cranianos graves, onde a cabeça, os ombros, os punhos e as mãos são as regiões do corpo mais afetadas. Objetivos: este estudo teve como objetivos quantificar a incidência de lesões relacionadas com a prática de boxe e a identificação de padrões de lesões e fatores de risco. Além disso, foi analisada a eficácia de medidas preventivas de lesões e as adaptações comportamentais após lesão. Metodologia: Foi utilizado um questionário para a recolha dos dados dividido em três partes: dados pessoais, experiência de treino e exposição e lesões. Resultados: 583 questionários foram analisados. Os resultados mostraram que 76% dos indivíduos eram do sexo masculino, e 70,5% nunca competiram. O sparring foi a técnica que levou a 34,3% das lesões, e a inflamação foi a lesão mais comum (28,1%). Discussão: A literatura demonstra que a incidência de lesão diminuiu no boxe amador nos últimos anos, mantendo-se no profissional. A incidência de lesão é superior no boxe profissional e o sparring é a técnica que leva a um maior número de lesões. Os alongamentos parecem ser o comportamento preventivo mais comum após lesão. Conclusões: Este estudo permite demonstrar que a altura, a frequência de competição, o nível de competição e o treino de força são os fatores mais associadas ao número de lesões nos praticantes de boxe.
- Mental health, overweight, and physical exercise in young portuguese adults : a cross-sectional studyPublication . Gonçalves, Tânia; Monteiro, Diogo; Matos, Rui; Couto, Nuno; Antunes, Raul; Diz, Susana; Amaro, Nuno; Jacinto, Miguel; Duarte-Mendes, PedroAbstract: The aim of this study was to see if there are any associations between mental health, Body Mass Index (BMI), and physical exercise (PE) in young Por tuguese adults. The sample consisted of 414 people aged between 18 and 25 years old. A sociodemographic questionnaire designed for this study and the Mental Health Inventory were used. To analyze the results, the total sample was divided according to the criteria “BMI ≥ 5 kg/m2”; “BMI < 25 kg/m2”; “does not practice PE”; and “practices PE”, and sample groups were formed with these names. It was found that there was an association between the dimensions of the Mental Health Inventory and the average time spent practicing PE in the total sample (r from 0.099 to 0.160) and in individuals with a BMI < 25 kg/m2 (r = 0.154 and 0.169). In individuals with a BMI ≥25 kg/m2, there was an association between the ‘BMI’ and depression variables (r = −0.174). In all groups, associations were found between the variables of age and BMI (r from 0.120 to 0.216). There was also a significant effect of group (non-exercise vs. exercise groups) on the dependent variables, Λ = 0.972, F(5, 408) = 2.329, p = 0.042, η2p = 0.28. This study confirms the association between PE and mental health and suggests that BMI may have an influence on the appearance of depressive symptoms in young Portuguese adults.
