- 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.
- 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.
