O presente projeto apresenta-se intimamente ligado com a mulher portuguesa e a
moda. Cada vez mais a moda está ligada às pessoas e ao que elas querem demonstrar
na sociedade, mas muitas mulheres têm dificuldades em encontrar roupas que lhes
agradem, devido ao seu tipo de corpo. Há cinco tipos de corpo diferentes, mas este
projeto, procura focar-se na mulher portuguesa, então vai trabalhar os três tipos de
corpos mais comuns em Portugal, sendo eles: o triângulo; o triângulo invertido e o oval.
Este projeto procura valorizar estes corpos através de uma coleção “cápsula” para cada
um deles, fazendo assim, com que este grupo de pessoas tenha uma coleção única para
si. Ao longo deste projeto, serão descritos os conceitos relacionados ao slow-fashion, à
cultura portuguesa, assim como os cinco tipos de corpos e o que os favorece. Será
também mencionado o processo de criação e realização do projeto, bem como, planos
para o futuro em relação ao mesmo.

Cardiometabolic diseases are one of the primary causes of mortality and morbidity worldwide and sedentary lifestyles are contributing factors to these pathologies. Physical exercise has been recognized as an important tool in the prevention and treatment of these diseases. However, there are still some doubts about the efficacy of certain type of physical exercise programs for older participants. The main goal of this study is to assess the impact of different aquatic-based physical exercise programs on risk markers of cardiometabolic diseases in older people. The study group will consist of non-institutionalized individuals, within the age group of 65 or older. The sample will be randomly divided into four groups, three experimental groups (EG) and one control group (CG). Participants fromthe EGs will be exposed to three physical aquatic-based exercise programs for a period of 28 weeks (continuous aerobic, interval aerobic and combined). The evaluated parameters include anthropometry, physical functions, mental health, cognitive function, carotid arteries intima-media thickness, heart rate variability and biochemical markers. The results will allow an interpretation of the impact of different aquatic-based physical exercise programs on cardiometabolic diseases markers and can also be used as a tool for professionals to prescribe adequate and more efficient physical exercise programs.
Background
Both physical inactivity and sedentary behavior are considered modifiable risk factors for chronic diseases and all-cause mortality. Adult office-workers spend most of their working day in sedentary behaviors, so they are particularly at high risk of developed chronic diseases (e.g., cardiovascular diseases, metabolic disorders like diabetes mellitus, . . .). It seems important to promote behavioral changes that could prevent or delay metabolic disease development. Evidence supports the use of exercise programs, however, to date there are several knowledge gaps and inconsistencies in the literature regarding the effects of Combined Training (i.e., aerobic plus resistance training) in sedentary healthy adults. This paper outlines an RCT designed to evaluate the effects of a 16-week combined training program on biochemical and immune markers of metabolic disease, lung function, salivary stress hormones and subjective quality of life (primary outcomes), as well as on body composition and physical fitness (secondary outcomes) in sedentary middle-aged office-workers. Furthermore, we aimed to assess the associations between the changes promoted by the exercise program and the different variables studied.
Methods and design
This is a single-blinded two-arm RCT with parallel groups. A minimum of healthy 40 officeworkers aged 40–64 years will be recruited to engage in a 16-week intervention study. After baseline assessments, participants will be randomized to one of the two groups: (1) combined training group or (2) control group. Baseline assessments will be repeated after 8 weeks of intervention (mid-testing) and upon completion of the intervention (post-testing).
Discussion
This RCT involves a multi-disciplinary approach and seems to be a relevant contribution to understanding the potential role of combined training in improving the metabolic profile, lung function, stress, and quality of life in adults. The results can provide important insights for clinical recommendations and for the optimization of strategies to prevent metabolic disorders in adults with sedentary jobs.
The 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.
Scientific evidence has shown that physical exercise is an effective way of improving several cardiovascular disease markers. However, few studies have tested its effectiveness whenperformed in aquatic environments. The purpose of this study was to test the impact of different aquatic exercise programs on the intima-media thickness of carotid arteries (IMT) and hemodynamic and biochemical markers of cardiovascular diseases in community-dwelling older persons. A total of 102 participants were randomly allocated into four groups: an aerobic exercise group (AerG) (n = 25, 71.44 ± 4.84 years); an aerobic interval group (IntG) (n = 28, 72.64 ± 5.22 years); a combined group (ComG) (n = 29, 71.90 ± 5.67 years); and a control group (CG) (n = 20, 73.60 ± 5.25 years). The AerG, IntG, and ComG participants took part in three different aquatic exercise programs for 28 weeks. The CG participants maintained their usual routines. All participants were evaluated for IMT, blood pressure, lipid profile, and MCP-1 and MIP-1α chemokines, pre- and post-intervention. Significant differences were found in the AerG for diastolic diameter (DD), in the IntG for peak systolic velocity (PSV), and in the ComG for DD and end-diastolic velocity (EDV). Regarding blood pressure, significant differences were found in AerG for systolic blood pressure (SBP) and diastolic blood pressure (DBP); in IntG for DBP; and in ComG for SBP, DBP, and heart rate (HR). Significant differences were found in the AerG and IntG for glucose (GLU). Lower plasma levels of monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein (MIP-1α) were found in the AerG and in the ComG for MCP-1 after the intervention. Aquatic physical exercise appears to improve cardiovascular health, regardless of the type of the program adopted. Aerobic programs (combined and continuous aerobic exercises) seemed to have a more beneficial effect in reducing important cardiovascular risk markers.
Evidence shows that physical exercise is important in maintaining an efficient
immune system during ageing. However, there are few studies that test the
impact of aquatic exercise programs on the immune system. This study aims to
analyze the impact of different physical exercise programs in aquatic
environment on the systemic hematological and inflammatory markers of
community dwelling elderly. One hundred and two elderly were randomly
allocated into four groups: a continuous aerobic exercise group (AerG) (n = 25,
71.44 ± 4.84 years); an interval aerobic exercise group (IntG) (n = 28, 72.64 ±
5.22 years); a combined exercise group (ComG) (n = 29, 71.90 ± 5.67 years); a
control group (CG) (n = 20, 73.60 ± 5.25 years). The AerG, IntG and ComG
participants took part in three different aquatic exercise programs over a 28-
weeks period. The CG participants maintained their usual routines during the
same time period. Blood samples were collected from all participants in order to
access hematologic indicators, by means of cell count, and the inflammatory
profile by ELISA. After 28 weeks, significant differences were found for several
hematologic variables in the AerG, IntG and ComG with increases in mean
corpuscular hemoglobulin (MCH), mean corpuscular hemoglobulin
concentration (MCHC), and hemoglobulin (Hb). Decreases in TNF-α levels
were found for all exercising groups. An increase in IL-10 levels, granulocytes to lymphocytes ratio (GLR) and a decrease in the TNF-α/IL 10 ratio, were found for the IntG. For the ComG decreases were also found
for the TNF-α, IL-1ß/IL-1ra ratios. The present study suggests that aquatic
exercise programs were able to improve the inflammatory profile of the
participants. Those in the exercise intervention groups showed a shift
towards lower pro-inflammatory levels while the non-exercising group
showed the opposite behaviour. The IntG and the ComG aquatic exercise programs appeared to be more effective than the AerG program in decreasing
chronic low-grade inflammation by mediating the production of higher levels of
anti-inflammatory cytokines. However, the differences found between the
exercising groups were small and may not have clinical significance.
Background: Sedentary behavior has been considered an independent risk factor to health. The aim of this systematic review and meta-analysis was to examine associations between objectively measured sedentary time and physical fitness components in healthy adults. Methods: Four electronic databases (Web of Science, Scopus, Pubmed and Sport Discus) were searched (up to 20 September 2020) to retrieve studies on healthy adults which used observational, cohort and cross-sectional designs. Studies were included if sedentary time was measured objectively and examined associations with the health- or skill-related attributes of physical fitness (e.g., muscular strength, cardiorespiratory fitness, balance). After applying additional search criteria, 21 papers (11,101 participants) were selected from an initial pool of 5192 identified papers. Results: Significant negative associations were found between total sedentary time with cardiorespiratory fitness (r = -0.164, 95%CI: -0.240, -0.086, p < 0.001), muscular strength (r = -0.147, 95%CI: -0.266, -0.024, p = 0.020) and balance (r = -0.133, 95%CI: -0.255, -0.006, p = 0.040). Conclusions: The evidence found suggests that sedentary time can be associated with poor physical fitness in adults (i.e., muscular strength, cardiorespiratory fitness and balance), so strategies should be created to encourage behavioral changes.
This 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.
