- Editorial: (Un)healthy lifestyles, aging, and type 2 diabetesPublication . Duarte-Mendes, Pedro; Silva, Fernanda M.; Teixeira, Ana M.Recent estimates from the IDF Diabetes Atlas indicate that diabetes affects 589 million adults worldwide in 2024, with type 2 diabetes (T2D) accounting for more than 90% of cases (International Diabetes Federation, 2025). This number is projected to reach 853 million by 2050. Age is an important risk factor for T2D, with estimates indicating that one in four adults with the disease (158 million) are over 65 years old.
- 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.
- Effects of combined aerobic-resistance training on health-related quality of life and stress in sedentary adultsPublication . Silva, Fernanda M.; Ferreira, José P.; Teixeira, Ana M.; Massart, Alain; Duarte-Mendes, PedroIIntroduction: Poor quality of life and psychological stress have been associated with worse clinical outcomes, including anxiety and depression disorders, cardiovascular diseases, metabolic syndrome, type 2 diabetes, and premature mortality. Evidence suggested that physically active adults were more likely to report better quality of life and increased capacity to deal with stress, compared to their sedentary peers. This study examines the effects of 16 weeks of combinedaerobic and resistance exercise training on health-related quality of life (HRQoL) and stress levels in sedentary adults. Methods: This study involved previously sedentary middle-aged workers (n = 36),randomized, and allocated into control (n = 18) and exercise (n = 18) groups. The exercise group performed 16 weeks of combined exercise training for 75 min, three times/week. The HRQoL was assessed using the SF-36 survey and Satisfaction with Life Scale. Stress levels were assessed subjectively using the Perceived Stress Scale and objectively by the salivary cortisol and alpha-amylase concentrations. Intra- and inter-group analysis were performed using a mixed ANOVA or Friedman’s test. Results: In relation to SF-36 results, a significant improvement in the mental component summary (p = 0.047, Kendall’s W = 0.170 (small effect)) and social functioning subdomain (p = 0.040, Kendall’s W = 0.179 (small effect)) was found for the exercise group after the intervention. A significant difference between groups was found in mean differences (Δ) in the mental health subdomain, with superiority in the exercise group (exercise group, Δ = 7.50 vs. control group, Δ = −5.00; p = 0.006). After 16 weeks of follow-up, the exercise group perceived reduced stress levels compared to the control group (exercise group, Δ = −3.67 points vs. control group, Δ = 0.94 points; p > 0.05); although not significant, this result is clinically relevant. The exercise program had no significant effect on salivary stress biomarkers. Discussion: The present study’s findings may have important clinical implications because they show that middle-aged sedentary workers are likely to benefit from adopting a regular combined exercise training regimen to promote better HRQoL (i.e., mental health component) and wellbeing.
- Effects of combined training during the COVID-19 pandemic on metabolic health and quality of life in sedentary workers : a randomized controlled studyPublication . Silva, Fernanda M.; Duarte-Mendes, Pedro; Carvalho, Eugénia; Soares, Carlos M.; Farinha, Carlos; Serrano, João; Paulo, Rui; Massart, Alain; Rodrigues, Rafael N.; Teixeira, Ana; Ferreira, José PedroThis study aimed to analyze the effects of a combined training (CT) program performed during the first national lockdown due to the COVID-19 pandemic on body composition, metabolic profile, quality of life and stress in sedentary workers, and examines whether changes in the metabolic profile are associated with changes in health-related outcomes which are modifiable by exercise. We evaluated 31 sedentary workers (48.26 ± 7.89 years old). Participants were randomly assigned to a CT group (i.e., performed 16 weeks of exercise) or to a non-exercise control group. The CT program consisted of 16-week of resistance and aerobic exercise. Body composition, glycemic and lipidic profiles, cardiorespiratory fitness (CRF), health-related quality of life and stress levels were assessed pre- and post-intervention. After the intervention period, the CT group demonstrated significantly lower waist and hip circumference (p < 0.05) values than the control group. The control group significantly increased the fasting glucose and HOMA-IR after 16 weeks follow-up (+4.74 mg/dL, p = 0.029; and +0.41 units, p = 0.010, respectively), whiles no significant changes were observed in the CT group in the same parameters (+3.33 mg/dL, p = 0.176; and +0.04 units, p = 0.628, respectively). No changes were observed in the lipid profile for either group (p > 0.05). A significant positive relationship was detected between the change in BMI with the changes in insulin and HOMA-IR (r = 0.643, p = 0.024; and r = 0.605, p = 0.037, respectively). In addition, the changes in CRF were negatively associated with the changes in total cholesterol (r = −0.578, p = 0.049). We observed differences between groups on perceived stress levels and physical, psychological, and environmental domains of quality of life, with the CT group showing better results. Moreover, the CT group improved perceived life satisfaction (+3.17 points, p = 0.038). The findings of the present study suggest that the participants who remained physically active during the first pandemic-related lockdown were able to mitigate the deleterious effects associated with a sedentary lifestyle.
- 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.
