  • Examining exercise motives between gender, age and activity: a first-order scale analysis and measurement invariance
    Publication . Rodrigues, Filipe; MOUTÃO, JOÃO; Teixeira, Diogo; Cid, Luis; Monteiro, Diogo
    Conceptualizing an exercise program according to exercisers motives seems to be crucial. Thus, adequate and validated scale assessing motives for physical activity is necessary. This study aimed to translate and validate the Exercise Motives Inventory – 2 (EMI-2), a scale assessing fourteen motives for regular physical activity in Portuguese exercisers. In addition, comparison of motives between groups were made according to gender, age, and fitness activity. For scale validation, data from two independent samples were collected: calibration (n = 820; female = 499) and validation (n = 733; female = 451) participants. For scale reliability and mean difference analysis, data from a new sample was collected (n = 515; female = 342). Results showed that data did not fit the original 51-item model. After reviewing item loadings, two items were eliminated, since they presented factor loadings below acceptable. Hence, the revised model encompassing 49-item had an adequate fit. Convergent and discriminant validity was achieved in the revised model, displaying acceptable construct validity. In addition, invariance criteria were respected between female and male Portuguese exercisers. Regarding mean comparison analysis, differences were found between gender, and across age and fitness activities. Nevertheless, in overall the majority of exercisers indicated “general health” and “physiological” motives as the most valued. The EMI-2 is a reliable scale assessing motives in Portuguese exercisers. This study suggests that exercise programs should be conceptualized considering motives, but also gender, age, and fitness activity.
  • Behavioral Regulation Sport Questionnaire: Gender and Sport Invariance in Portuguese Athletes
    Publication . Monteiro, Diogo; Teixeira, Diogo; Vitorino, Anabela; Moutão, João; Rodrigues, Filipe; Machado, Sérgio; Cid, Luis
    This study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across the gender and four different sports. In addition, we examined nomological validity via basic psychological needs satisfaction. Participants totaled 1,812 Portuguese athletes (1,220 males and 592 females; aged 15–59 years, Mage ¼ 17.72, SD ¼ 5.51) from football (n ¼ 596), basketball (n ¼ 273), swimming (n ¼ 800), and parasport (n ¼ 143). The BRSQ measurement model was invariant across the gender and these four sports. The scale confirmed nomological validity in that satisfaction of the basic psychological needs positively predicted autonomous forms of motivation and negatively predicted more controlled motivation and amotivation as suggested by self-determination theory. In light of this evidence for BRSQ construct validity, composite reliability, nomological validity, and invariance across the gender and four different sports, this scale is a useful tool for the coaches of the aforementioned sports in their efforts to evaluate their athletes’ motivation.
  • Motivational patterns in persistent swimmers: a serial mediation analysis
    Publication . Teixeira, Diogo Santos; Pelletier, Luc; Monteiro, Diogo; Rodrigues, Filipe; MOUTÃO, João; Marinho, Daniel Almeida; Cid, Luis
    Objective: The main objective of the present study was to examine the associations between coach-created task-involving climate and athletes' intentions to continue practicing sport, through a serial mediation analysis that included basic psychological needs satisfaction (BPN), self-determined motivation (SDM) and enjoyment. Methods: 799 elite swimmers (450 males, 349 females; aged 12-22 years, M = 16.65, SD = 2.83) participated in the present study. Groups were created according to age, years of experience, and gender. Results: Serial Mediation Analysis provided support for the proposed model where BPŃs and enjoyment represent the most important mediators between task-involving climate and athletes' intentions to continue sport practice. Conclusion: Enjoyment stands out as the most relevant predictor of intention to persist and as a significant mediator in the relation between task-involvement climate, BPN, SDM, and long-term sports practice. The task-involving climate created by coaches appears to set in motion a sequence where the satisfaction of basic needs and SDM lead to more enjoyment and increased persistence among young athletes.
  • Physical exercise and sedentary lifestyle: health consequences.
    Publication . Monteiro, Diogo; Machado, Sérgio; Moutão, João; Bento, Teresa; Vitorino, Anabela; Alves, Susana; Rodrigues, Filipe; Lima, João Maciel; Teixeira, Diogo Santos; Murillo-Rodriguez, Eric; Cid, Luis
    Perhaps the greatest barriers for achieving major advances in public health in the twenty-first century result from the paralysis of the pandemic paradigm or from the widespread inability to envision alternative or new models of thought. Human movement represents a complex behavior that is influenced by personal motivation, health and mobility problems, genetic factors, and social and physical environments in which people live. These factors influence the propensity to engage in sedentary behaviors or in physical activity. However, the biological, social, and environmental pathways leading to sedentary behavior versus physical activity may be different. In addition, the health effects associated with sedentary behavior and physical activity may be the result of different biological mechanisms. Thus, our objective was to discuss the importance of physical exercise on health-related outcomes and the consequences of sedentary lifestyles. Research on sedentary behavior has been growing;however, the evidence for its determinants is relatively sparse. More studies are needed to obtain more conclusive results because it is fundamental to understand these complex relationships related to the practice and the acquisition of active and healthy lifestyles as opposed to a sedentary lifestyle.
  • Can Interpersonal Behavior Influence the Persistence and Adherence to Physical Exercise Practice in Adults? A Systematic Review
    Publication . Rodrigues, Filipe; Bento, Teresa; Cid, Luis; Neiva, Henrique Pereira; Teixeira, Diogo; Moutão, João; Marinho, Daniel; Monteiro, Diogo
    Objective: Motivation seems to be a fundamental indicator of long-term physical exercise adherence. Self-Determination Theory (SDT) argues that social environment plays a central role in the satisfaction of basic psychological needs, which might directly affect the quality of one’s motivation. Individuals who appear to be more self-determined tend to persist longer at certain behaviors. Therefore, this body of work intends to analyze the relationship between motivational variables and behavioral outcomes in the exercise context, having as theoretical background the Self-Determination Theory. Methods: This systematic review was conducted through an electronic search on Web of Science, PubMed, SPORTDiscus, and PsycINFO. Data such as instruments, main predictors and results were collected from studies published between 1985 and 2018. A total of 35 empirical studies were considered for a detailed analysis. Results: Results showed the relevance of autonomy support performed by exercise professionals, as well as the major contribution that these behaviors have toward the satisfaction of basic psychological needs, besides the inherent benefits of developing more autonomous regulations. According to the literature, few studies have analyzed interpersonal thwarting behavior and the way this relates to basic psychological needs’ frustration. Nether less, there seems to be a negative relationship between less self-determined regulations and exercise practice. Conclusion: Despite the existence of numerous cross-sectional studies that demonstrate positive correlations between SDT and behavioral outcomes in the exercise context, longitudinal research that analyzes all six dimensions of interpersonal behaviors and their relationship with persistence and adherence to exercise proves to be crucial. However, according to this review, interventions based on SDT appear to be fundamental when it comes to promote the maintenance of a long-term exercise practice.
