- An overview of the effects of physical exercise programs on individuals with Intellectual and Developmental DisabilitiesPublication . Jacinto, Miguel; Ferreira, José Pedro; Monteiro, Diogo; Antunes, Raul; Campos, MJ; Matos, RuiBeing aware of the relevance of physical exercise in individuals with Intellectual and Developmental Disabilities (IDD), we intend to conduct a brief review on the importance of regular physical exercise for this population. An approach will be taken in order to acknowledge the barriers to the high rates of sedentary lifestyles in this population, the potential benefits of physical exercise, and the essential aspects for a correct assessment, prescription, and implementation of these programs in the population with IDD, through a reflection supported by scientific evidence. The current overview aims to provide relevant information regarding the health benefits of physical exercise in individuals with IDD, as the basis for QoL promoting more active and healthier lifestyles, namely through structured physical exercise. In addition, it is also a useful tool for consultation by exercise professionals since adjusted indoor and outdoor exercise programs are listed.
- Un análisis conductual de los predictores de la adherencia al ejercicio y su impacto económico en el contexto del fitnessPublication . Antunes, Raul; Susano Jacinto, Miguel Ângelo; Matos, Rui; Morquecho Sánchez, Raquel; Amaro, Nuno; Cid, Luis; Couto, Nuno; Santos Teixeira, Diogo; Monteiro, DiogoEste estudio pretendía examinar la relación entre las percepciones de los clientes sobre los comportamientos de los fisiólogos del ejercicio, los tipos de motivación y su influencia posterior en la adherencia al ejercicio durante un periodo de seis meses. Además, evaluamos el impacto financiero del abandono de los clientes en los ingresos de los gimnasios durante este periodo. Métodos: Una muestra de 1.803 individuos (edades 18-54; M = 26,61, SD = 5,48) inscritos en gimnasios de todo Portugal participaron en este estudio. Resultados: Durante el periodo de seis meses, el 42% de los clientes cancelaron sus abonos, lo que supuso una pérdida de ingresos mensual estimada de 28.659,60 euros al final del sexto mes. Acumulativamente, los gimnasios experimentaron una pérdida total de ingresos de 110.393,27 euros durante el periodo de estudio. Conclusiones: Los hallazgos sugieren que los comportamientos de apoyo a las necesidades por parte de los fisiólogos se asocian positivamente con la motivación autónoma, que a su vez promueve la adherencia al ejercicio a largo plazo. Por el contrario, los comportamientos que frustran las necesidades están relacionados con la motivación controlada, que afecta negativamente al mantenimiento del ejercicio. Estos datos ponen de relieve la importancia de las estrategias de motivación tanto para la retención de clientes como para la sostenibilidad financiera de los gimnasios.
- Analysis of Frailty Indices Based on Sociodemographic and Clinical Determinants in Older WomenPublication . Rodrigues, Filipe; Monteiro, Diogo; Susano Jacinto, Miguel Ângelo; Matos, Rui; Amaro, Nuno; Pocinho, Ricardo Filipe da Silva; Gordo, Sara; Dias Tavares da Silva, Sílvia Manuela; Antunes, RaulBackground: The aim of this study was to analyze levels of frailty, across physical, psychological, social, and overall dimensions, according to marital status, age, number of diagnosed illnesses, and number of medications taken in community-dwelling older women. Methods: The study included a total of 94 older women, aged between 60 and 89 years. All participants completed a sociodemographic and clinical questionnaire, as well as an instrument to measure physical, psychological, and social frailty, along with the total frailty score in the study participants. Group comparison test, such as the Kruskal–Wallis test, was applied. Results: Statistically significant differences (p < 0.05) in frailty were associated with marital status, clinical burden, and polypharmacy, with widowed/divorced individuals, those with more diagnosed diseases, and those taking more medications exhibiting higher physical and total frailty levels, while psychological frailty was notably higher in the oldest age group. Conclusions: The results indicate that physical and social interventions should be more relevant for older women with greater social isolation, as they may increase frailty indices and consequently the risk of hospitalization, institutionalization, and mortality.
- Application of the hierarchical model of intrinsic and extrinsic motivation in the context of exercise: a systematic reviewPublication . Viveiros, Bernardo; Jacinto, Miguel; Antunes, Raul; Matos, Rui; Amaro, Nuno; Cid, Luis; Couto, Nuno; Monteiro, DiogoGiven the increase in sedentary lifestyles and physical inactivity, various psychosocial approaches have been used to combat this epidemic. Several studies have used Self-Determination Theory (SDT) as a theoretical framework for studying behavioral change, as well as the Hierarchical Model of Intrinsic and Extrinsic Motivation (HMIEM) which, based on SDT, aims to explain how different levels of generality can be responsible for behavioral consequences. The aim was to investigate the associations between the variables that make up the HMIEM model applied to the context of physical exercise (gym exercisers). Following the PRISMA protocol and the PECOS strategy, the Web of Science, PubMed, Scopus, and SPORTDiscus atabases were used to search for experimental and non-experimental studies written in English. Seven studies were considered for analysis and subjected to a methodological quality assessment The results showed that the variables that make up the social factors (e.g., supportive/thwarting behaviors) tend to be associated with satisfaction of basic psychological needs (BPN) (r = 0.51, p < 0.01; r = −0.73, p < 0.01) and with frustration of BPN (r = −0.39, p < 0.01; r = 0.78, p < 0. 01), BPN satisfaction and frustration tend to be associated with autonomous forms of motivation (r = 0.57, p < 0.01; r = −0.63, p < 0.01) and controlled forms of motivation (r = −0.76, p < 0.01; r = 0.46, p < 0.01) and autonomous and controlled forms of motivation are associated with behavioral consequences (e.g., intention) (r = 0.19, p < 0.01; r = −0.17, p < 0.01). This systematic review covers interpersonal behaviors and the bright and dark sides of SDT, showing that the positive alignment between the psychosocial determinants that make up the horizontal axis of the HMIEM is fundamental for adherence to and maintenance of sustainable physical exercise practices, and future studies should now address these issues in a longitudinal manner and perhaps move on to study the vertical axis of the HMIEM.
- Aptidão física funcional e qualidade de vida em pessoas com dificuldade intelectual e desenvolvimental: estudo exploratórioPublication . Diz, Susana; Jacinto, Miguel; Monteiro, Diogo; Matos, Rui; Garrido, Nuno Domingos; Costa, Aldo M.; Antunes, RaulApesar do exercício físico ser um bom indicador para a promoção da saúde, a população com dificuldade intelectual e desenvolvimental tende a apresentar elevados níveis de inatividade física que influenciam a sua aptidão física, saúde e qualidade de vida. Neste sentido, o presente estudo teve como objetivo analisar a aptidão física funcional e a QdV, assim como as associações entre estas mesmas, de uma amostra de população com DID. Foram avaliados 37 indivíduos com DID (42,54± 11,12 anos), através dos testes levantar e sentar na cadeira, timed up and go, caminhar durante 6 minutos, com o propósito de averiguar a aptidão física e a Escala Pessoal de Resultados para mensurar o bem-estar físico. Foram aplicadas correlações de pearson e verificou-se a correlação entre o bem-estar físico e os testes de levantar e sentar e caminhar 6 minutos. Os resultados sugerem uma associação entre as capacidades funcionais medidas através dos testes e o bem-estar físico, sugerindo que a promoção destas competências pode influenciar positivamente o bem-estar físico da amostra utilizada.
- Assessment of Isokinetic Strength of Knee Extension/Flexion of Individuals With Intellectual Developmental Disabilities—Systematic Review With Protocol ProposalPublication . Jacinto, Miguel; Caseiro, André; Antunes, Raul; Monteiro, Diogo; Campos, MJ; Matos, Rui; Ferreira, José Pedro; Gomes, Beatriz BranquinhoMuscle performance is a crucial determinant of physical function in the daily lives of individuals with intellectual developmental disabilities (IDD), with lower strength levels often leading to loss of independence. The isokinetic dynamometer has been established as a reliable method for assessing muscle performance in this population. This article outlines the design of a protocol to be adopted to assess isokinetic knee strength in individuals with IDD. Using systematic review methodology, electronic searches were conducted in PubMed, Scopus, SPORTDiscus, and Web of Science databases, including articles published between January 1990 and September 2022. The key terms were combined with the Boolean operator “AND” or “OR”. After the methodological process, 23 studies were included for analysis. The protocol proposal consists of 8 phases, covering previous considerations: (a) warm-up, (b) familiarization; (c) equipment adjustment, choosing the limb to evaluate and in what type of action (concentric and/or eccentric); (d) number of repetitions and sets; (e) the rest duration; (f) angular velocity to be tested; and (g) parameters for analysis. It is intended that this article provide insights into the development of a useful tool for the various stakeholders interested in assessing the isokinetic knee strength of individuals with IDD.

- Behavioral regulation in sport questionnaire and sport motivation scale-II: a scale comparisonPublication . Bica, Joana; Susano Jacinto, Miguel Ângelo; Matos, Rui; Amaro, Nuno; Antunes, Raul; Couto, Nuno; Cid, Luis; Forte, Pedro; Monteiro, DiogoIntroduction: This study compared the psychometric properties of two primary instruments for assessing sport motivation based on Self-Determination Theory: the Sport Motivation Scale-II (SMS-II) and the Behavioral Regulation in Sport Questionnaire (BRSQ). Methods: A cross-sectional analysis evaluated the scales’ internal consistency, factor structure, convergent and discriminant validity, and model fit, which required post-hoc modifications. Measurement invariance and adherence to the theoretical simplex pattern were also tested. Results: The BRSQ demonstrated generally acceptable reliability, while the SMS-II showed deficiencies in its introjected, external, and amotivation subscales. Both scales faced validity challenges in distinguishing adjacent motivational constructs. Although measurement invariance was supported, correlations deviated from the theoretical quasi-simplex pattern. Discussion: The BRSQ appears more robust, but neither scale is flawless. Researchers must select instruments aligned with their specific objectives and interpret scores cautiously due to these psychometric limitations. This underscores the need for refined tools to better capture the dynamic complexity of motivation in sports.
- Calidad percibida, calidad global del servicio, satisfacción global del servicio, valor percibido del servicio e intenciones futuras de un evento deportivo: Percepciones de los triatletas portuguesesPublication . Jacinto, Miguel; Margarido, Cristóvão; Sousa, Marlene; Carlos Marques, José; Barroca de Sousa Varela, Jorge Alexandre; Amaro, Nuno; Morquecho Sánchez, Raquel; Matos, Rui; Monteiro, Diogo; Antunes, RaulEl objetivo de este estudio fue analizar la estructura factorial de un modelo para evaluar la percepción de satisfacción y calidad de un acontecimiento deportivo. Se desarrolló un análisis factorial confirmatorio para probar la estructura factorial. La presente muestra comprendió 208 participantes triatletas portugueses (hombres = 148; Edad media = 41.29 ± 11.28). De estos participantes, 169 declararon practicar ejercicio físico más de 4 veces por semana y 153 dijeron haber participado en 5 o más pruebas de triatlón. Los resultados actuales mostraron que el modelo de medición presentaba un ajuste adecuado (modelo muestral total: χ2/df = 2.748, B-S p < .001, TLI = .928, CFI = 0.940, SRMR = 0.075, RMSEA = 0.092 (CI = 1.068, 1.671). Estos resultados apoyan el uso de este modelo para evaluar todas las dimensiones asociadas a un acontecimiento deportivo, en particular el triatlón.
- The Combined Effect of the Mediterranean Diet and Physical Activity on the Components of Metabolic Syndrome in Adults: A Systematic Review of Randomised Controlled TrialsPublication . Teixeira, Luíza; Monteiro, Diogo; Matos, Rui; Antunes, Raul; Susano Jacinto, Miguel ÂngeloMetabolic syndrome (MetS) is a global public health challenge, characterized by the coexistence of cardiometabolic risk factors such as abdominal obesity, dyslipidaemia, hypertension, and insulin resistance. Non-pharmacological strategies, including the Mediterranean diet (MD) and physical activity (PA), have been widely studied for their potential to prevent and manage MetS. This systematic review aimed to synthesize the evidence on the combined effect of MD and PA on MetS components in adults, based on randomized controlled trials (RCTs). Twenty-two RCTs published between 2018 and 2024 were included, involving 11,478 participants. The interventions ranged from 8 weeks to 3 years and combined adapted or hypocaloric MDs with moderate-to-high-intensity PA, typically including walking, aerobic exercise, or high-intensity interval training (HIIT), performed 3 to 7 times per week. The combined interventions resulted in reductions in body weight (−2.5 to −7.2 kg), body mass index (−0.7 to −2.2 kg/m2), waist circumference (−5.1 to −7.8 cm), and blood pressure (up to −9.0 mmHg systolic and −6.7 mmHg diastolic). Improvements in HDL cholesterol, triglyceride levels, and insulin sensitivity were also observed. These findings suggest that integrated interventions based on the Mediterranean lifestyle are effective in reducing MetS components and may support future public health strategies.
