- Aptidão física e qualidade de vida em indivíduos com deficiência intelectual e de desenvolvimentoPublication . Jacinto, Miguel; Brito, João; Oliveira, Rafael; Martins, Alexandre; Francisco, Ruben; Vitorino, AnabelaA maioria dos indivíduos com Deficiência Intelectual e de Desenvolvimento (DID) adota um estilo de vida sedentária e inativa, tendo consequentemente fraca capacidade funcional e de composição corporal, apresentando uma relação com o seu estado de saúde. Avaliar a composição corporal e averiguar a sua influência com a capacidade funcional/aptidão física, numa população com DID. 16 indivíduos com DID avaliados na composição corporal por bio impedância multifrequência, capacidade funcional e força dos membros inferiores, com recurso a dinamómetro isocinético. Não se verificaram diferenças, na capacidade funcional e nas variáveis da composição corporal, entre grupos com diferentes gras de deficiência. Verificou-se correlações entre o género diferenças significativas, na capacidade funcional e nas variáveis da composição corporal, entre grupos com diferentes graus de deficiência. Verificaram-se correlações entre o género e as variáveis da composição corporal, apresentando o género masculino valores mais favoráveis nas variáveis percentagem de massa gorda (%MG) (r= -0,758; p=0,001), gordura visceral (GV) (r= -0,589; p=0,016), massa celular corporal (MCC) (r= 0,625; p=0,010), água extra celular (AEC) / água corporal total (ACT) (r= -0,607; p=0,013) e no ângulo de fase (AF) a 50khz (r= 0,529; p=0,035). O rácio ACT/massa isenta de gordura (MIG) e o rácio AEC/ACT apresentam valores de indivíduo saudável, respetivamente, 73,26±0,36% e 0.36-0.39%. O AF foi menor no género feminino e nas idades mais avançadas, bem como com o aumento da %MG. O grau de deficiência parece não influenciar a capacidade funcional e as variáveis da composição corporal, nesta amostra. De salientar, o AF que reflete a boa integridade celular relacionado à proporção de AEC e de água intracelular, apresenta valores dentro dos parâmetros normais, ainda que baixos.
- Effects of Exercise Programs on Anxiety in Individuals with Disabilities: A Systematic Review with a Meta-AnalysisPublication . Jacinto, Miguel; Frontini, R.; Matos, Rui; Antunes, RaulAnxiety symptoms are increasingly prevalent in individuals and may affect their quality of life. Physical exercise (PE) has been shown to be an effective method for reducing anxiety symptoms in the general population. The present study aimed to identify if PE programs can be a good method to reduce anxiety symptoms in individuals with disabilities, through the methodology of a systematic review with a meta-analysis. The PubMed, Web of Science, Scopus, and SPORTDiscus databases were used, considering the period from 2001 to 2021. The descriptors used were: "cerebral palsy", "motor disability", "physical disability", "vision impairment", "visual impairment", "vision disability", "intellectual disability", "mental retardation", "intellectual disabilities", "hearing impairment", "hearing disability", "multiple disabilities", "physical activity", "exercise", "sport", "training", and "anxiety", with the Boolean operator "AND" or "OR". The systematic review with a meta-analysis was carried out in the period between May and June 2021. The Z values (Z-values) obtained to test the null hypothesis, according to which the difference between means is zero, demonstrated a Z = 2.957, and a corresponding p-value of 0.003. Thus, we can reject the null hypothesis, and affirm that PE promotes positive effects and can be a good method or methodology for the reduction of anxiety symptoms of individuals with disabilities.
- How does the level of physical activity influence eating behavior? A self-determination theory approachPublication . Fernandes, Vanessa; Rodrigues, Filipe; Jacinto, Miguel; Teixeira, Diogo; Cid, Luis; Antunes, Raul; Matos, Rui; Reigal, Rafael; Hernández-Mendo, Antonio; Morales-Sánchez, Verónica; Monteiro, DiogoPhysical activity and diet are two predominant determinants of population health status that may influence each other. Physical activity has been identified as a behavior that may lead to a healthier diet and regulates eating behaviors. This research aimed to investigate how the level of physical activity is associated with the motivation related to eating behaviors and, consequently, the eating style individuals have on a daily basis. This was a cross-sectional study in which participants completed an online questionnaire that assessed the following variables: the level of physical activity, the motivation toward eating behavior, and the type of eating behavior. In total, 440 individuals (180 men and 260 women) who regularly exercised in gyms and fitness centers aged between 19 and 64 years (M = 33.84; SD = 10.09) took part in the study. The data were collected following the Declaration of Helsinki and with the approval of the Ethics Committee of the Polytechnic of Leiria. For the statistical analysis, mean and standard deviations were first calculated, as well as bivariate correlations between all the variables of interest. Then, structural equation model analyses were performed considering the levels of physical activity as the independent variable, motivations toward eating behavior as the mediators, and eating styles as the dependent variables. It was concluded that a greater level of physical activity leads to a more self-determined type of eating regulation, which in turn results in less constricted eating behaviors that are influenced by external factors and emotional factors.
- Influence of physical fitness on the perception of physical well-being and quality of life in individuals with intellectual and developmental difficultiesPublication . Jacinto, Miguel; Oliveira, Rafael; Brito, João; Vitorino, AnabelaPhysical capacities, health and quality of life (QOL) are improved through physical exercise (PE). Some studies corroborate these effects in individuals with Intellectual and Developmental Difficulty (IDD). In this sense, the objective of the study was to verify the association of physical fitness with the perception of physical well-being and quality of life (QOL) in individuals with IDD. Sixteen individuals with IDD (mean ± standard deviation, age, 34.2 ± 10.61 years; body mass, 72.42 ± 18.23 kg; height, 158.3 ± 9.17 cm) were assessed in body composition by bio impedance method, InBody S10 (Biospace Co, Ltd, Seoul, Korea), in the 30-second chair stand test, Timed Up And Go (TUG), 6-minute walking test (6-min) (Rikli & Jones, 1999), medicine ball throwing (3kg-ball) (Harris et al., 2011) and lower limb strength (LMS) using the HUMAC2015®/NORM™ (Tosca Drive, Stoughton, USA). “Physical Well-Being” and “Total QOL” were assessed using the Personal Outcomes Scale (Claes et al., 2010; Loon et al., 2010; Simões et al., 2016), through self-reported responses (individuals and technicians). Pearson and Spearman correlations were applied for p<0.05. In the female gender, there were associations between the tests for assessing muscle strength in the extension and flexion of LMS (angular velocity of 60º) and the responses of the technicians in the domains of “Physical Well-Being” (respectively, r=0.729 , p=0.026; r=0.802, p=0.009) and “Total QoL” (respectively, r = 0.706, p = 0.033; r = 0.767, p = 0.016). It was found that strength, endurance and aerobic capacity do not seem to be associated with physical well-being and QOL. According to the results, it is necessary to carry out studies with larger and more representative samples of each gender and degree of disability.
- Influence of physical fitness on the perception of physical well-being and quality of life in individuals with Intellectual DisabilityPublication . Jacinto, Miguel; Oliveira, Rafael; Brito, João; Simões, Cristina; Vitorino, AnabelaPhysical capacities, health and quality of life (QOL) are improved through physical exercise in individuals with Intellectual Disability (ID). The aim of the present study was to verify the association of physical fitness with the perception of physical well-being and QOL in individuals with ID. Sixteen individuals with ID were evaluated by bioimpedance, functional tests (“6-minute walk test” (6MIN), “Timed Up and Go” (TUG), “30-s Chair Stand” (L/S), and “medicine ball throw”) and isokinetic dynamometer (lower limbs [LL]). The Personal Outcomes Scale (POS) was used to measure “Physical Well-Being” and “Total QoL”. Pearson and Spearman correlations were applied (p< 0.05). Correlations were found only in the female gender between the muscular strength in the extension/flexion of the LL (60º/s) and the responses of the reference technicians in the domains of “Physical Well-Being” (respectively, r= 0.729, p= 0.026; r= 0.802, p= 0.009) and “Total QOL” (respectively, r= 0.706, p= 0.033; r= 0.767, p= 0.016). It was found that strength, endurance and aerobic capacity do not seem to be associated with the physical well-being and QOL of the sample.
- Passion for sport as a mediator between the basic psychological needs and life satisfaction of athletes with disabilitiesPublication . Rodrigues, Filipe; Vitorino, Anabela; Cid, Luis; Bento, Teresa; Jacinto, Miguel; Antunes, Raul; Teixeira, Diogo; Monteiro, DiogoThe present study examined the potential impact of basic psychological needs and passion for the practiced sport on the life satisfaction of athletes with disabilities. A mediation model was tested, hypothesizing that autonomy, competence, and relatedness are associated with athletes' life satisfaction through their passion (harmonious and obsessive) for the sport. One hundred thirty-one athletes participated in this study, ranging in age from 15 to 59 years (M = 27.78; SD = 9.31). Athletes completed questionnaires regarding their satisfaction of basic psychological needs in sports, their passion for the sport, and overall life satisfaction. Perceptions of competence and relatedness were associated with harmonious passion (β = 0.37, p < 0.01; β = 0.21, p < 0.05, respectively), while perceptions of autonomy were linked to obsessive passion (β = 0.39, p < 0.05). Furthermore, harmonious passion was linked to life satisfaction (β = 0.40, p < 0.01), and only the indirect effect of competence on life satisfaction through harmonious passion was significant. The results suggest that autonomy satisfaction does not necessarily translate into higher levels of harmonious passion. However, competence and relationships play a significant role in the life satisfaction of athletes who have a harmonious passion for their sport.
- Prescription and Effects of Cardiorespiratory Training in Individuals with Intellectual Disability: a Systematic ReviewPublication . Jacinto, Miguel; Oliveira, Rafael; Martins, Alexandre D.; Brito, João; Matos, Rui; Ferreira, José PedroThis study aims to systematize effects of cardiorespiratory training (CT) programs in individuals with intellectual disability (ID) and identifying the fundamental and structuring aspects for the prescription of CT. This systematic review was carried out through four databases (Pubmed, Web of Science, Scopus, and SPORTDiscus), considering data from the period between 2013 and 2022. From 257 studies, 12 studies were included in this systematic review. Three studies used interval CT, while seven used continuous CT. Seven were carried out in the population with Down syndrome, while only three were carried out with participants with ID. The CT programs had the following characteristics: duration of 8 to 12 weeks, weekly frequency of three sessions, for 20 to 60 min, the intensity of 50% to 80% of maximal heart rate or 70% to 80% of peak oxygen consumption, using an ergometer cycle or an outdoor walking. The studies reported improvements in cardiorespiratory function, lipid, hemodynamic and metabolic profile, body composition, and neuromuscular and cognitive capacity. This review presents characteristics and recommendations that technicians can follow when structuring, prescribing, and implementing CT programs to individuals with ID.
- Prescription and effects of strength training in individuals with intellectual disability—A systematic reviewPublication . Jacinto, Miguel; Oliveira, Rafael; Brito, João; Martins, Alexandre; Matos, Rui; Ferreira, JoséThe practice of physical exercise (PE), especially strength training (ST), has health benefits in the healthy population; however, the literature is scarce in the recommendations related to the population with intellectual disability (ID). This study represents the first analysis on the topic and aims to examine the structure and efficacy of ST experimental intervention programs in individuals with ID. This systematic review was carried out between January and April 2021, using the PubMed, Web of Science, Scopus, and SPORTDiscus databases, according to the PRISMA guidelines. From a total of 166 studies, eight were included in the present systematic review. The studies included a total of 280 individuals (18.23 2.86 years old). The main features of the exercise programs are: 12 weeks average duration, three weekly sessions of 45–60 min, six to seven exercises targeting the main muscle groups, two to three sets, 6–12 repetitions, and avoiding free weights for safety reasons. The main results showed increments in strength, balance and fat-free mass and decrements in fat mass and waist circumference. It is a useful guideline for PE technicians to prescribe and adjust correctly in order to not only promote physical fitness, but improve the quality of life of individuals with ID.
- Recomendações para a avaliação e prescrição de treino da força em Indivíduos com dificuldade Intelectual e desenvolvimental: revisão narrativaPublication . Jacinto, Miguel; Monteiro, Diogo; Oliveira, Rafael; Brito, João; Vitorino, AnabelaExistem diversos benefícios através da realização de programas de exercício físico (EF) em indivíduos com Dificuldade Intelectual e Desenvolvimental (DID), no entanto a literatura apresenta uma escassez na implementação e um reduzido número de estudos com metodologias e tipos de treino muito diversos. Intervenções de curto prazo, número reduzido de estudos longitudinais, lacunas metodológicas e métodos de treino inapropriados, dificultam conclusões mais explícitas e consensuais ao nível da prescrição e dos seus resultados. Contudo, os programas de EF, em particular, o treino da força (TF) que tem sido associado à diminuição do risco de aparecimento de doenças cardiovasculares e metabólicas, pode ser uma mais-valia para o indivíduo com DID, atendendo à prevalência de diversas comorbilidades, nomeadamente hipertensão, colesterol e diabetes tipo II. O presente estudo tem por objetivo identificar os aspetos fundamentais e estruturantes para a prescrição de TF, nomeadamente os métodos de avaliação, intensidade, duração, frequência, exercícios adequados e a sua relação com os resultados, através da metodologia com recurso à revisão narrativa, partindo da caracterização de vários programas de TF implementados em indivíduos com DID. Os resultados são apresentados sob a forma de recomendações para a avaliação e prescrição de programas de TF, na população com DID.
