- Associação entre composição corporal e aptidão física funcional na população idosaPublication . Martins, João Tiago Farinha; Paulo, Rui; Ramalho, André; Duarte-Mendes, Pedro; Silva, Fernanda M.; Petrica, João; Serrano, JoãoEste estudo teve como objetivo analisar a correlação entre as variáveis de composição corporal e as variáveis de aptidão física funcional na população idosa. A amostra reuniu 114 sujeitos. Para avaliar a Composição Corporal utilizou-se uma balança de bioimpedância Inbody 270. Mediu-se a altura com um estadiómetro e calculou-se o Índice de Massa Corporal. Para a aptidão física utilizou-se a Bateria de testes de aptidão motora Rikli e Jones (1999) que avalia a capacidade funcional, consistindo esta na capacidade para realizar atividades diárias de forma natural e segura, sem existir uma fadiga exagerada (Nunes & Santos, 2010). Ao correlacionar as variáveis de composição corporal e aptidão física concluiu-se que que quanto melhor a condição corporal melhor a capacidade física. O Índice de Massa Corporal e Massa Gorda e Percentagem de Massa Gorda com Massa Gorda foram as correlações mais fortes entre variáveis de composição corporal. Nas correlações entre variáveis de composição corporal e testes de aptidão física evidenciou-se a correlação entre Levantar/Sentar e Flexão do Braço. Os resultados do estudo mostram que a aptidão física tem influência na composição corporal permitindo uma melhor qualidade de vida.

- Changes in body composition and blood pressure in students entering in university education: a 32-month longitudinal studyPublication . Paulo, Rui; Duarte-Mendes, Pedro; Silva, Fernanda M.; Serrano, João; Ramalho, André; Petrica, JoãoThe university access entails some constraints on the lifestyles of young students, including their physical activity patterns. This study objective to know if the students who entered university education and who attend courses in sports sciences have more adjusted values in terms of body composition and blood pressure in relation to students taking other courses. METHODS: Thirty-one students (age 19.81±1.64 years) participated in this study, of both sexes, divided in two groups: sports students group (N.=19); and students group from other courses (N.=12). Body composition was evaluated, namely Body Mass Index (BMI), waist circumference (WC), hip circumference (HC), using tetrapolar bio impedance (Tanita BC-601) the percentage of body fat (%BF), muscle mass (MM) and bone mineral (BM) were calculated. Blood pressure (SBP/DBP) was also measured (Omron DBP HEM-907). We checked the distribution of the sample. For the variables with normal distribution, we used the paired t-test and for the other variables with non-normal distribution we used the Wilcoxon test. Comparing baseline and follow-up, in sports students, there are differences for the variables WC, HC, MM, BM and SBP. In these comparisons, there was an increase in the absolute values of all variables, except for the %BF, SBP and DBP variables. The group of students from other courses, presents differences for the BMI, WC, HC, %BF and DBP. Students from the Sports course present better overall results in terms of body composition and blood pressure, compared to students from other courses.
- Changes in metabolic and inflammatory markers after a combined exercise program in workers : a randomized controlled trialPublication . Silva, Fernanda M.; Duarte-Mendes, Pedro; Ferreira, José Pedro; Carvalho, Eugénia; Monteiro, Diogo; Massart, Alain; Farinha, Carlos; Soares, Carlos M.; Teixeira, AnaPurpose: We investigated the effects of a 16-week combined exercise training on body composition, metabolic and inflammatory markers in sedentary middle-aged workers. We also assessed whether significant alterations in metabolic markers were associated with changes in health-related outcomes. Methods: This randomized controlled trial involved 46 participants randomly allocated into control and exercise groups. The exercise group performed 16-week combined aerobic and resistance training for 75 min/session, 3 times/week. Fasting blood samples were collected at baseline and after 16-week intervention to determine lipid profile, metabolic and inflammatory markers as primary outcomes. Results: A total of 36 participants completed the intervention (53.70 ± 6.92 years old) (n = 18 in each group). Waist circumference (interaction effect: F = 7.423, p = 0.002), fat mass (interaction effect: F = 5.070, p = 0.011), and muscle mass (interaction effect: F = 5.420, p = 0.007) were improved in the exercise group compared to the control group. Fasting glucose increased after the 16-week follow-up (time effect: F = 73.253, p < 0.001), without an intergroup difference. Insulin levels were greater in the control compared to exercise group (group effect: F = 6.509, p = 0.015). The control group tended to increase the HOMA-IR index (interaction effect: F = 3.493, p = 0.070) and to decrease the QUICKI index (interaction effect: F = 3.364, p = 0.075) to a greater extent compared to the exercise group. Exercise group reduced leptin (interaction effect: F = 11.175, p = 0.002) and adiponectin (interaction effect: F = 4.437, p = 0.043) concentrations in a greater magnitude than control group. IL-6 (time effect: F = 17.767, p < 0.001) and TNF-α (time effect: F = 9.781, p = 0.004) concentrations decreased after the intervention, without an intergroup difference. IL-17A levels increased in the control compared to exercise group (interaction effect: F = 5.010, p = 0.033). Effects on adiponectin, IL-6 and IL-17A levels seem to depend on baseline BMI, age, and sex. Percentage changes in leptin correlated positively with changes in HOMA-IR index in the exercise (r = 0.565, p = 0.015) and control (r = 0.670, p = 0.002) groups. Conclusions: A combined training program can be an effective strategy to improve body composition and inflammatory markers and prevent marked reductions in insulin sensitivity among middle-aged workers.
- Correlation between the aerobic capacity, grip strength and cognition function and cardiometabolic diseases risk markers in the non-institutionalized old adults: a cross-sectional analysisPublication . Serrano, João; Santos, Helder; Silva, Fernanda M.; Cascante-Rusenhack, Marcio; Paulo, Luís; Ferreira, José Pedro; Farinha, CarlosThe elderly population is constantly growing worldwide. One of the characteristics of aging is the decrease in functional fitness and cognitive function, leading to the appearance of cardiometabolic disorders. Methodology: The aim of this study is to verify the association between aerobic capacity, handgrip strength and cognition with risk markers for cardiometabolic diseases and mental health in community dwelling elderly. The study consists of a cross-sectional analysis of baseline data from a 28-week randomized controlled trial, with a sample of 102 participants (mean age 72.32 ± 5.25 years). The sample was evaluated for anthropometry, functional fitness, heart rate variability, carotid artery intima and mean thickness (IMT), cognitive function, mental health and biochemical markers. Correlations were evaluated using Pearson's statistical analysis and interpreted according to Cohen's (1988). Results: Statistically significant correlations were found between aerobic capacity (2m-ST) and markers of functional, cardiovascular, biochemical, cognitive function and mental health fitness. Handgrip strength (HG) was statistically significantly correlated with anthropometric measurements, various indicators of functional fitness, biochemical markers, cognitive function, and mental health variables. Finally, cognitive function (MMSE) was correlated with anthropometric measures, functional fitness, cardiovascular and biochemical markers, and mental health. These data suggest that aerobic capacity, handgrip strength and cognitive function may be hypothetically associated with cardiovascular disease risk markers.
- Editorial: (Un)healthy lifestyles, aging, and type 2 diabetesPublication . Duarte-Mendes, Pedro; Silva, Fernanda M.; Teixeira, AnaRecent 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 Pedro; Teixeira, Ana; 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 Pedro; Teixeira, Ana; 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.
