“…However, despite the growing popularity of HCFC worldwide, and in Brazil in particular, these spaces have not received a great deal of attention from researchers investigating adherence, retention and dropout rates in PA programs, with most efforts in this field being concentrated on supervised interventions, randomized controlled trials, and established group exercise programs outside HCFC settings (Berry et al 2018, Kuehl et al 2016, Lorenz et al 2015. Alternatively, some research has looked at these rates within HCFC settings but from a marketing perspective, establishing satisfaction levels and intention to repurchase as some of the main variables to understand PA adherence as consumer behavior (Cañamero et al 2019, Gonçalves et al 2016, Hurley 2004. While this body of work has provided invaluable insights into external and internal factors impacting on individual's initiation, adherence and long-term maintenance of PA practice, still very little is known about dropout, lapse and return patterns and its implications on adherence to exercise programs in the unsupervised setting of a HCFC (Clavel San Emeterio et al 2019, Costa et al 2009, Garay et al 2014.…”
