- Adapting the Short Grit Scale with Exploratory Structural Equation Modeling for Portuguese College StudentsPublication . Frontini, Roberta; Monteiro, Diogo; Rodrigues, Filipe; Matos, Rui; Antunes, RaulThe Short Grit Scale (Grit–S) is a self- and informant-report version of the longer Grit Scale, and it retains the 2-factor structure of the original scale. Our purpose in this research was to measure trait-level perseverance and passion for long-term goals by translating and validating the Grit-S for Portuguese respondents. Our participants were 572 college students (135 female, 437 male; age range 18–30 years, M age = 21.47, SD = 2.29 years) from twelve Portuguese universities. Our data confirmed the scale’s two-factor structure (“consistency of interests” and “perseverance of effort”) and demonstrated appropriate adjustment values (CFI = 0.999, TLI = 0.981, SRMR = 0.017, RMSEA = 0.001, CI90%= 0.000–0.041). We found the adapted scale to be invariant for sex. Use of the scale confirmed an association between grit and well-being. These results imply that other investigators and practitioners interested in this scale may now apply it with Portuguese young adults.

- Alterações no desempenho motor em 3 meses de confinamento devido à pandemia provocada pelo SARS-CoV-2 em crianças e jovens praticantes de atletismoPublication . Coelho, Luís; Rebelo-Goncalves, Ricardo; Antunes, Raul; Salvador, Rogério; Amaro, Nuno; Monteiro, Diogo; Lopes, Nataniel; Matos, RuiEste estudo analisou as alterações no desempenho de crianças e jovens praticantes de atletismo em 4 tarefas motoras: corrida de velocidade (CV), corrida de resistência (CR), salto horizontal (SH) e lançamento dorsal (LD), após o confinamento obrigatório e interrupção dos seus treinos em contexto normal, devido à pandemia SARS-Cov-2. Foram avaliados 46 praticantes de atletismo (23 raparigas; 23 rapazes), com idades compreendidas entre 9,3 e 13,2 anos de idade (M=11,5; DP=1,1) em dois momentos separados por cerca de 80 dias: antes e depois do 1.º confinamento. Os resultados demonstram uma diminuição dos valores médios de desempenho nas 4 tarefas motoras avaliadas, com diferenças estatisticamente significativas para 3 das 4 (p<,01), com exceção para a CV. Analisados os dados por grupos, nos atletas que mantiveram a prática de exercício físico regular durante o confinamento (43,5%), o decréscimo no desempenho apenas se revelou estatisticamente significativo para o SH e LD (p<.01), enquanto que para os atletas que não mantiveram a prática de exercício físico regular o decréscimo apenas se revelou estatisticamente significativo para a CR e LD (p<0,05). Comparados os grupos para as diferenças de desempenho entre os dois momentos, não foram constatadas diferenças estatisticamente significativas (p>0,05). Estes resultados corroboram os efeitos negativos do confinamento e das alterações no processo de treino nas camadas mais jovens, mesmo para os que mantiveram uma prática de exercício físico regular durante a interrupção dos seus treinos em contexto normal.
- 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 Exercise Intensity Preferences, Tolerance, Competence, and Their Implications for Behavioral Intentions in Fitness SettingsPublication . Rodrigues, Filipe; Jacinto, Miguel; Antunes, Raul; Amaro, Nuno; Matos, Rui; Monteiro, DiogoThis study aims to comprehensively investigate the interrelationships among exercise intensity preference, tolerance, competence satisfaction, competence frustration, and exercise intentions within the fitness domain. The research involved 114 participants aged 18 to 59 years (M = 33.23; SD = 10.542), with an average height of 166.02 cm (SD = 15.856) and weight of 68.02 kg (SD = 13.658). The path analysis revealed positive correlations among constructs, except for the link between exercise intensity tolerance and competence satisfaction. Notably, exercise intensity preference positively related to competence satisfaction (β = 0.20, CI90% = 0.12, 0.40), while both preference and tolerance were negatively linked to competence frustration (preference: β = −0.27, CI90% = −0.44, 0.03; tolerance: β = −0.17, CI90% = −0.03, 0.24). Competence satisfaction (β = 0.37, CI90% = 0.13, 0.34) and competence frustration (β = −0.29, CI90% = −0.48, −0.09) significantly influenced exercise intentions. An indirect effect existed between exercise intensity preference and intentions (β = 0.11, CI90% = 0.03, 0.21), contrasting with the lack of such effect for intensity tolerance (β = 0.05, CI90% = −0.01, 0.14). Intentions explained 16% of the variance. In conclusion, this study underscores the intricate connections between exercise intensity traits and intentions, shedding light on factors influencing individuals’ exercise persistence.
- Anthropometric Measures, Muscle Resistance, and Balance in Physically Active, Aged AdultsPublication . Rodrigues, Filipe; Antunes, Raul; Matos, Rui; Jacinto, Miguel; Monteiro, Diogo; Forte, Pedro; Monteiro, A. M.; Barbosa, Tiago M.Objectives: This study aimed to examine the relationship between age, body mass index, muscle strength, and balance in physically active, aged adults. Methods: Eighty-five participants were recruited for this study, having an average age of 70.31 years (SD = 9.90), ranging from 50 to 92 years. Twenty-six (30.6%) participants were male and fifty-nine (69.4%) were female. The participants had an average body mass index of 27.30 kg/m2 (SD = 3.62), ranging from 20.32 to 38.58 kg/m2. Participants undertook the Timed-Up and Go to test balance, and the chair-stand test to assess lower body strength. Hierarchical regression analyses were conducted. Three models (Model 1, 2, and 3) were tested to assess their relationships with balance: M1—Lower body muscle strength; M2—Lower body muscle strength and body mass index; M3—Lower body muscle strength, body mass index, and age. Results: All hierarchical models displayed significant variance. The third model explained 50.9% of the variance in dynamic balance, [F(3, 81) = 27.94, p < 0.001, R = 0.71, Ra2 = 0.51]. The difference in Ra2 between the first, second, and third models was statistically significant (p < 0.05). Age, body mass index, and lower body muscle strength had significant (p < 0.05) correlations with balance. In terms of the significant impact of each predictor, age had the strongest association with balance (p < 0.05). Conclusions: The results are useful to understand mechanisms or diagnose people at risk of fall.
