Factors influencing sport persistence still represent a knowledge gap - the experience of a systematic review.

Investigating sport persistence can make a significant contribution to a thorough examination and understanding of the factors underlying an athlete's activity, integrating physical activity, sports motivation and commitment. This systematic review aimed to detect the papers focusing on the factors influencing sport persistence following the levels of Bronfenbrenner's and Bauman's ecological models. Following the PRISMA guidelines, by the EBSCO Discovery Service Search Engine, 512 records were detected, of which 21 met the criteria. Factors influencing sport persistence show a huge variety. Individual factors and micro-system level were overrepresented. Meso- and macro-level factors are underrepresented and measured only with other (individual or micro-system level) factors. Most factors detected at the individual (e.g. gender, age, career-related variables and positive psychological factors), micro- (e.g. family, peers and coaches), meso- (e.g. climate), and macro-level (cultural, societal, and institutional influences) were positively correlated with sport persistence, i.e. supporting the persistent behaviour of the athletes regarding participating in one's sporting activity. In conclusion, there is still room for further research concerning sport persistence. Including variables belonging to the meso- and macro-system and conducting longitudinal research should be considered which would allow us to better understand the nature of sport persistence.
