Background Exercise has been recognized as a promising and emerging treatment for individuals recovering from addiction. The purpose of this article was to systematically review scientific studies using exercise as a means to improve, sustain, or treat addictions, and to provide suggestions for the future use of exercise as a treatment method for addiction. Methods Using PRISMA guidelines, a database search was conducted for articles that tested the impact of exercise interventions on addiction-related outcomes. To be included, peer-reviewed experimental design studies had to use human subjects to investigate the relationship between exercise and the treatment of or recovery from addiction. Garrard’s Matrix Method was used to extract data from reviewed articles ( n = 53). Results Nearly three quarters of the studies reviewed documented a significant change in addiction-related outcomes (e.g., more days abstinent, reduced cravings) in response to exercise exposure, particularly while someone was receiving treatment at an in or outpatient clinic. Many studies investigated the effect of acute bouts of exercise on nicotine dependence, and many studies had small sample sizes, leaving room for future research on how exercise might benefit people recovering from substance and process addictions. Conclusion Results affirm that exercise can be a helpful aspect of addiction treatment. Future researchers should investigate different exercise settings (e.g., group-based exercise vs individual) and explore exercise maintenance and the long-term outcomes following discharge from treatment facilities.

Purpose The purpose of this study is to assess factors related to sorority women connecting with people who exacerbate feelings of exercise guilt and body dissatisfaction (BD), both of which preclude compulsive exercise. Design/methodology/approach In all, 207 sorority women (egos) completed online surveys measuring physical activity, BD, compulsive exercise and egocentric networks (n = 1,105 social ties/alters). Two random coefficient multilevel models assessed factors related to an ego connecting to someone who makes her feel: guilty about her exercise habits and good about her looks. Findings Exercise patterns within networks related to how often an alter made ego feel guilty about her exercise habits; alter gender and communication frequency related to how often an alter made ego feel good about her looks; and ego’s BD score was related to both feelings of guilt and body satisfaction. Originality/value The findings of this study support and extend literature highlighting the importance of someone’s immediate social network on their body image and related behaviors.

Purpose This paper aims to use social network analysis (SNA) to determine whether compulsive exercise (CE) was related to social connections and network position among participants of group-exercise programs. Design/methodology/approach Members from two group-exercise programs (Gym 1: n = 103; Gym 2: n = 56) completed an online survey measuring their social connections within the program, CE, depressive symptoms and sense of belonging. Network position was calculated for each person based on network centrality scores (i.e. closeness, eigenvector centrality). Linear network autocorrelation models determined whether respondents reported similar CE as their network ties (i.e., network effects) and whether network position was related to CE in these networks. Findings Eigenvector centrality (i.e., being connected to popular/important people within the network; Gym 1: parameter estimate [PE] = 0.51, p < 0.01, Gym 2: PE = 0.39, p = 0.02) and network effects (i.e. having similar CE scores as direct network ties; Gym 1: PE = 0.07, p < 0.01, Gym 2: PE = 0.19, p < 0.01) were related to CE among participants in these programs. Originality/value This study builds on existing SNA research suggesting the importance of social connections and network position on CE, and, to the best of the authors’ knowledge, is the first to explore these effects among group-exercise participants. This study describes how the social environment can impact, both positively and negatively, someone’s susceptibility for CE and supports fostering social connections within group-exercise programs as a way to potentially combat harmful CE among its participants.
