- Nível de atividade física e hábitos de vida saudável de universitários portuguesesPublication . Esteves, Dulce; Vieira, Sérgio; Brás, Rui; O'Hara, Kelly; Pinheiro, PauloEste estudo visa avaliar o nível de atividade física e hábitos de vida saudável de alunos de duas universidades portuguesas. Utilizou-se o Questionário Internacional da Atividade Física para avaliar o nível de atividade física dos estudantes, juntamente com questões de avaliação dos hábitos de vida. 35% dos estudantes inquiridos apresenta nível de atividade física baixo, reportando a disponibilidade, os horários, a distância e o preço, como causas de não participação nos programas de atividade física existentes. Os principais objetivos associados à prática de atividades física são melhorar a condição física, relaxamento, diminuição do stress, diversão, prevenção de doenças e aumento da autoestima. Os estudantes evidenciam alguns comportamentos de risco ao nível do consumo excessivo de tabaco, álcool e drogas. As Universidades deverão promover a prática regular de atividades físicas no seio académico e sensibilizar para os malefícios advindos do sedentarismo e comportamentos de risco no bem-estar e saúde desta população.
- Supervised Exercise Patterns among Diabetic and Non-diabetic Portuguese AdultsPublication . Esteves, Dulce; Gouveia, Ana; Rodrigues, Ricardo; Pinheiro, Paulo; Brás, Rui; O'Hara, Kelly; Duarte, PauloBackground. Physical activity (PA) is a keystone of diabetes management, but although self-exercise is beneficial, supervised exercise (SE), adapted to individual characteristics, and is more effective. Objectives. The main research goal is to compare SE patterns among diabetic and non-diabetic Portuguese adults. Methods. A total of 484 participants (85 diabetics, 399 non-diabetics), aged 41-90 years old (mean=58.9; SD=11.9) were interviewed. PA level was assessed using short form of the International Physical Activity Questionnaire. Attendance in different SE programs was evaluated across three kinds of PA programs providers: gym/health-clubs; swimming pools and other club/ sports facilities. Itens like Barriers to Exercise; Intention to participate; Importance of the structure and PA information sources were also evaluated. Independent t-tests were used to examine the difference between the group means, and Levene’s test was used to check the homokedasticity of the groups’ variances. Results. PA level of diabetics (32% low; 25% moderate; 44% high) and non-diabetics (29% low; 33% moderate; 39% high) display no differences. 90% of diabetics do not attend SE. The main barrier for diabetics’ non-participation is the perception that the exercise is not adequate to their health. Doctors are the preferred information source for diabetics and they rely less on information provided by the Internet, with may impair on-line campaigns. Conclusion. Promoting exercise in diabetics should shift the focus from "promoting physical activity" to "promoting SE".
- Physical activity level as a booster of entrepreneurial intention: a social innovation approachPublication . Rodrigues, Ricardo; Marques, Carla; Esteves, Dulce; Brás, Rui; Santos, Gina; Gouveia, Ana; Duarte, Paulo; Pinheiro, Paulo; O'Hara, Kelly; Marques, VanessaThis study aims to investigate if engaging in physical activity (PA) and gender influences people’s entrepreneurial intention (EI). A survey for measuring EI and PA was developed and administered to the general population. The data were collected with a questionnaire distributed across all continental Portuguese regions. A two-way analysis of variance was used to test the influence of PA level and gender in EI. The results highlight that PA and gender have an impact on EI. This study’s main practical implication is that evidence was found that people need to be involved in more PA, especially in high PA level, because the results show that there is an association with increased levels of EI. This paper contributes to filling a gap in the literature by identifying the importance of PA for the increase of EI. This relationship may be a consequence of skills promoted by the practice of PA and also the development of some personal psychological and cognitive characteristics such as autonomy, risk tolerance, and leadership. The main implication resulting from this study is that it is essential to develop and booster PA into society, namely through PA programmes in organisations, not only for improving persons’ health condition but also as a social benefit, that can promote social innovation and entrepreneurship.
- Motor intervention and assessment instruments in Autism Spectrum DisordersPublication . Lourenço, Carla; Esteves, DulceAbstract The practice of physical activity in people with disabilities provides important health benefits (Wind, Schwend, & Larson, 2004; Chanias, Reid, & Hoover, 1998), particularly in individuals with autism spectrum disorder (ASD). Several motor interventions have been suggested as beneficial for this population. Considering this variety, it is important to synthesize the different existing programs, the population in which they are applied. This research aims to review the motor interventions used in children with ASD, as well as the evaluation methods used, so that it becomes clear what the options are for motor work with this population. All the studies presented showed improvements in participants. A literature search was conducted in Web of Science, SCOPUS and Google Scholar 2013, to include research studies that evaluate motor intervention in children with ASD. Fifteen studies meet inclusion criteria. Results show that motor intervention programs that have been carried out are quite diverse, from dance, trampoline training, balance training or fundamental motor skills, for example, to evaluate motor skills which used different test batteries, one of the most common is the motor proficiency test of Bruininks-Oseretsky. On the other hand, other methods were used to evaluate the social interaction like Gilliam Autism Rating Scale or Autism Rating Scale. We conclude that to improve the motor fitness of children with ASD different strategies can be followed. As the revised programs use different evaluation tools, it is difficult to compare the results obtained with each other. A motor intervention that comprises different types of exercises and materials, using ludic exercises may be a potentially more effective strategy.
- Physical activity patterns and perceptions among portuguese type 2 diabetic and non-diabeticPublication . Esteves, Dulce; Gouveia, Ana; Rodrigues, Ricardo; Pinheiro, Paulo; Brás, Rui; O'Hara, Kelly; Duarte, PauloBackground. The increasing prevalence and incidence of type 2 Diabetes has turned it into a worldwide epidemic. Although Physical Activity (PA) may play an essential role in the prevention and management of this disease, sedentary lifestyles continue to increase among diabetics. Besides, there is evidence to believe that diabetics and non-diabetics show different patterns of PA behavior, perceptions and information seeking. Objectives. This study aims to analyze diabetics and non-diabetics differences regarding (1) PA patterns (level, barriers, goals/expectations and preferred activities); (2) PA-related information sources and (3) evidenced perception on the need and importance of PA. Methods. Using data from 485 Portuguese subjects aged between 41 and 90 years old, differences between diabetics (n=85) and non-diabetics (n=400) were analyzed with Pearson’s chi-square and independent t-test. Results. The study concludes that 32% of diabetics that are physically inactive. Their attitude toward PA is not much different from non-diabetics. Nevertheless, the importance given to the time available and the schedules of activities as well as exercising with friends were more relevant for diabetics. Diabetics considered that the exercise is not safe for their health condition and present lower expectation towards exercise. Regarding information seeking behavior about PA, diabetics use as leading information source doctors and less online information. Conclusion. Diabetics and non-diabetics give different importance to PA. Results establish a foundation for the development of effective tailored communication strategies to promote PA among the diabetics.
- Effects of Backpacks on Ground Reaction Forces in Children of Different Ages When Walking, Running, and JumpingPublication . Barbosa, João P.; Marques, MC; Neiva, Henrique; Esteves, Dulce; Alonso-Martínez, Alicia M; Izquierdo, Mikel; Ramirez-Campillo, Rodrigo; Alvarez, Cristian; Marinho, DanielBackpacks for transporting school loads are heavily utilized by children, and their mechanical advantages have been allowing children to transport heavy loads. These heavy loads may increase ground reaction forces (GRFs), which can have a negative effect on joints and bone health. The aim of this study was to investigate the effect of backpacks on the GRFs generated by children during walking, running, and jumping. Twenty-one children from the fifth (G-5, n = 9) and ninth (G-9, n = 12) grades walked, ran, and jumped over a force plate. When walking, the G-5 had GRF increments in the first (17.3%; p < 0.001) and second (15.4%; p < 0.001) peak magnitude, and in the total integral of the vertical force (20%; p < 0.001), compared to the control condition (i.e., no backpack), and the G-9 had increments of 10.4%, 9%, and 9% (p < 0.001), respectively. The G-9 did not prolong their total stance time (p > 0.05), unlike the G-5 (p = 0.001). When running, total stance time increased 15% (p < 0.001) and 8.5% (p < 0.001) proportionally to the relative load carried, in the G-5 and G-9, respectively. Peak GRF did not increase in any group when running or landing from a jump over an obstacle. It was found that GRF was affected by the backpack load when walking and running. However, when landing from a jump with the backpack, schoolchildren smoothed the landing by prolonging the reception time and thus avoiding GRF peak magnitudes.
- Physical activity level and perceptions about exercise in patients with OsteoporosisPublication . Esteves, Dulce; Pinheiro, Paulo; Brás, Rui; Gouveia Rodrigues, Ricardo; Gouveia, Ana; O'Hara, Kelly; Duarte, PauloOsteoporosis is a major health concern around the world. Physical activity (PA) is an essential preventive and therapeutic approaches for osteoporosis. This investigation aims to evaluate PA level and of perceptions about exercise of osteoporosis patients, regarding (1) importance of exercise on osteoporosis condition (IE); (2) balance between exercise benefits and risks (B/R); (3) importance of participation in exercise programs (IP); (4) major risks (R); (5) major benefits (B). PA level of 73 postmenopausal Portuguese women (mean=74.3, SD=8.7 years) with diagnosed osteoporosis (T-score < - 2.5 by DXA) was assessed by IPAQ. A complementary questionnaire was designed to evaluate perceptions about exercise. Descriptive statistics were used to analyse data. IPAQ analysis reported 21.9% high; 35.6% moderate and 42.5% low PA. 35.6% of patients consider that exercise has no impact in preventing osteoporosis evolution and 19.2% refers that it is only partially important. 63.0% considers that exercise has more disadvantages than benefits. About IP, 65.8% of women found daily activities more adequate then exercise programs. Main disadvantages reported (R) were risk of fall (87.7%) risk of bone injury (83.6%); risk of vertebral fractures (63.0%) and risk of increase pain (52.1%). Main benefits found were related to calcium fixation (83.6%); lower body weight (78.1%); increase bone density (69.9%); and increase muscular tonus (61.6%). Results suggest that the adherence to an active lifestyle is dependent on the capacity to change perceptions of osteoporosis patients about exercise. Exercise is medicine if patients acknowledge that exercise brings greater benefits than risks.
- Physical activity and supervised exercise among hypertensives and normotensives: status and barriersPublication . Esteves, Dulce; Duarte, Paulo; Pinheiro, Paulo; Brás, Rui; Rodrigues, Ricardo; Gouveia, Ana; O'Hara, KellyPurpose Physical activity (PA) is considered central to hypertension prevention and management. The main purpose of this article is to compare supervised exercise (SE) patterns among hypertensive and normotensive Portuguese adults. Methods A total of 966 participants aged between 15 and 90 years old (mean 41.9; SD 19.5) were surveyed face-to-face in public places across Portugal. Participants were considered hypertensives (n=144) if they have systolic and diastolic blood pressure higher than 160 and 90 mmHg or report taking antihypertensive medication. PA was assessed using the International Physical Activity Questionnaire (IPAQ). Descriptive statistics, Chi-square test for associations and t test for independent samples were used to analyze data. Results Hypertensive individuals show a higher prevalence of sedentary lifestyle than normotensive (31% vs 20%). About 40% of hypertensive patients have a high level of physical activity. Several signifcant diferences were found between hypertensives and normotensives regarding the causes for non-participation, information sources and motivation to participate. For infrastructures, only the quality of the equipment (p=0.032), innovative activities (p=0.027), and the opportunity to socialize (p=0.000) are capable of diferentiating the two groups. Conclusions This study shows the prevalence of sedentary behavior among the hypertensive population. Hypertensives and normotensive behavior reveal diferent patterns on the barriers, sources of information, and perception regarding the structures. Service providers seem incapable to make hypertensives aware of the risks associated with PA and the benefts associated with SE. More information is needed to make hypertensives aware of the benefts of SE programs.
- Evaluation of Risks and Benefits of Physical Activity: Fighting a Societal BurdenPublication . Brás, Rui; Esteves, Dulce; Rodrigues, Ricardo; Duarte, Paulo; Gouveia, Ana; O'Hara, Kelly; Pinheiro, PauloPhysical Activity (PA) is considered a coadjutant factor in the control of hypertension, helping to control this societal burden. This study investigates the factors that may influence the adoption of PA recommendations by hypertensive individuals by comparing physical activity patterns among hypertensives and normotensives and the importance placed on PA by both groups. Data from 966 Portuguese participants aged between 18 to 90 years old, representing hypertensives (n=144) and normotensives (n=822) were collected using a face-to-face questionnaire. The results show significant differences between the two groups in terms of causes of non-participation and dropping out, preferred PA activities, perceived knowledge, and information-seeking behaviour. The main barriers to exercise reported by hypertensives were the perception that PA is not adequate or even dangerous to their health. Doctors must be considered a key factor in promoting exercise. When compared to normotensives, hypertensives feel that PA information available is not appropriate (p=.0006). Hypertensives consider that existing programmes will not meet their needs and do not like traditional fitness classes, such as those in gyms. The fear of risks associated with exercise seems to be a significant barrier that impairs PA participation.
- Effect of the Internet and online social media on awareness of ACSM physical activity recommendationsPublication . Esteves, Dulce; Pinheiro, Paulo; Brás, Rui; Rodrigues, Ricardo Gouveia; Gouveia, Ana; O'Hara, Kelly; Duarte, PauloIntervention strategies to increase physical activity (PA) that can reach many people in a cost-effective manner are desired. Web-based interventions have shown promising results, but little investigation focus the effect of use Internet Sites and online social media as information sources on PA knowledge. This investigation aims to evaluate the effect of seeking for PA information on Internet Sites and online social media on awareness of ACSM PA recommendations for health promotion, among college students. The study included a randomly recruited sample of 658 college students (32.1% males; 67.9% females), aged 20.8, SD 2.9 years. A survey was designed to evaluate the use different PA information sources and the awareness of ACSM PA recommendations. 63.2% of respondents were not accurately knowledgeable of the ACSM PA recommendations. Interviewed use Internet Sites (55.8%) and online social media (29.1%) to seek for PA information. Looking for PA information online presents a negative influence on awareness of ACSM recommendations (P= .003 for Internet Sites and P= .022 for online social media).Despite efforts to promote PA and widespread knowledge on ACSM recommendations, about two thirds of interviewed students can not accurately identify adequate PA characteristics for health improvement. The use of new information technologies as PA information source seems to lead to lower level of knowledge, what could be related with poor quality of PA information on web.
