“…As such, there has been a stern call for interventions and treatment protocols that counteract the negative effects of using antipsychotic medication in the treatment of psychotic illness, with increased physical activity being a top complementary choice (eg, International Physical Health in Youth (iphYs) Working Group, 2013).3.2 | Physical activity interventions have been successful with SMI, and, more specifically, FEP populationsNumerous studies have shown that for people with SMI, physical activity can improve cardiorespiratory fitness and/or lower BMI to protect against the deleterious health outcome and accompany the diagnoses (eg,Rosenbaum, Hobson-Powell, Davison, Elliot, & Ward, 2017;, alleviate symptoms of mental illness (eg,Bonsaksen & Lerdal, 2012;Schuch et al, 2016), improve cognitive functioning(eg, Firth et al, 2016), enhance social competence and self-reliance (eg,Soundy et al, 2014), and bolster markers of overall mental health and quality of life(eg, Firth et al, 2015;Rosenbaum et al, 2014;Soundy et al, 2014). Interventions that use sport as a mode of physical activity for people with SMI have reported functional recovery and quality of life benefits such as a sense of achievement, purpose and belonging; positive sense of identity and enhanced confidence; and positive social experiences (eg,Carless & Douglas, 2016;Soundy et al, 2015).In recent years, there has been a growing amount of promising research on exercise-based early interventions specifically for the treatment and recovery of psychosis. The early stages of psychosis, particularly the time following a FEP, are considered a critical time in which the detrimental trajectory of the psychological and physical…”
