- 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.
- Is the light at the end of the tunnel bright? Associations between preference and tolerance of the intensity, basic psychological needs and behaviour in exercise contextPublication . Viveiros, Bernardo; Antunes, Raul; Susano Jacinto, Miguel Ângelo; Matos, Rui; Amaro, Nuno; Cid, Luis; Couto, Nuno; Monteiro, DiogoIn recent years, sedentary behaviour and physical inactivity have seen an evident increase. Many individuals who embark on an exercise regimen end up leaving it within the first three to six months, often citing barriers such as a lack of time or motivation. Research shows that the pleasure and enjoyment derived from exercise play a crucial role in preventing people from giving up. This suggests that theories related to the emotional aspects of exercise, including an individual’s exercise intensity preference and tolerance, should be integrated into broader motivation theories such as Self-Determination Theory (SDT). This chapter aims to provide a theoretical framework for these theories, emphasised by empirical evidence and proposes potential avenues for future research.
