A total of 588 persons from Pelotas \/ RS \/ Brazil (405 gym users and 183 subjects following personal training) completed the Portuguese version of the three questionnaires, i.e. the Perceived Autonomy Support Climate Exercise Questionnaire, Basic Psychological Needs in the Exercise Scale and Behavioral Regulation in the Exercise Questionnaire \u22122. The results support the factorial structure of the questionnaires used in this sample. There was a significant multivariate effect of context on self-determination for physical exercise training [Wilks\u2019 \u03bb = 0.934, F (10, 576.000) = 4.03, p &lt; 0.001, \u03b7<jats:sup>2<\/jats:sup> = 0.01]. The hypothesized structural equation model, which considered the self-determination theory, showed a good fit to the data (S-B \u03c7<jats:sup>2<\/jats:sup> = 234.703; p= .001; df = 52; \u03c7<jats:sup>2<\/jats:sup>\/df = 4.514; SRMS = .049; NNFI = .906; CFI = .926; RMSEA = .077; RMSEA 90% CI = .067 \u2212 .088). However, in the comparative analysis, the perception of autonomy support, relatedness and competence were significantly higher in the context of personal training, while the amotivation and external regulation were significantly higher in the context of fitness academies.<\/jats:p>","DOI":"10.1515\/hukin-2015-0052","type":"journal-article","created":{"date-parts":[[2015,7,14]],"date-time":"2015-07-14T11:48:40Z","timestamp":1436874520000},"page":"241-249","source":"Crossref","is-referenced-by-count":19,"title":["Self-Determination and Physical Exercise Adherence in the Contexts of Fitness Academies and Personal Training"],"prefix":"10.1515","volume":"46","author":[{"given":"Ingi Petitemberte","family":"Klain","sequence":"first","affiliation":[{"name":"- University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), Research Centre in Sport, Health and Human Development (CIDESD), Vila Real, Portugal."}]},{"given":"Dihogo Gama","family":"de Matos","sequence":"additional","affiliation":[{"name":"- University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), Research Centre in Sport, Health and Human Development (CIDESD), Vila Real, Portugal."}]},{"given":"Jos\u00e9 Carlos","family":"Leit\u00e3o","sequence":"additional","affiliation":[{"name":"- University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), Research Centre in Sport, Health and Human Development (CIDESD), Vila Real, Portugal."}]},{"given":"Lu\u00eds","family":"Cid","sequence":"additional","affiliation":[{"name":"- Sport Sciences School of Rio Maior (ESDRM-IPS), Research Centre in Sport, Health and Human Development (CIDESD), Vila Real, Portugal."}]},{"given":"Jo\u00e3o","family":"Mout\u00e3o","sequence":"additional","affiliation":[{"name":"- Sport Sciences School of Rio Maior (ESDRM-IPS), Research Centre in Sport, Health and Human Development (CIDESD), Vila Real, Portugal."}]}],"member":"374","published-online":{"date-parts":[[2015,7,10]]},"container-title":["Journal of Human Kinetics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/content.sciendo.com\/view\/journals\/hukin\/46\/1\/article-p241.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.sciendo.com\/article\/10.1515\/hukin-2015-0052","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,4,10]],"date-time":"2021-04-10T00:34:35Z","timestamp":1618014875000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.sciendo.com\/article\/10.1515\/hukin-2015-0052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,6,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2015,7,10]]},"published-print":{"date-parts":[[2015,6,1]]}},"alternative-id":["10.1515\/hukin-2015-0052"],"URL":"https:\/\/doi.org\/10.1515\/hukin-2015-0052","relation":{},"ISSN":["1899-7562"],"issn-type":[{"value":"1899-7562","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,6,1]]}}}
