Effects of CrossFit intervention on students’ physical fitness in physical education: a systematic review and meta-analysis

Based on the process of study collection, the research team identified N = 60 records from databases. Among them, SCOPUS n = 22, Web of Science n = 9, PubMed n = 28, ScienceDirect n = 1. Consequently, N = 17 full-text articles were assessed for eligibility screening, and N = 9 were excluded. However, at the phase of manual reference lists searching, N = 6 articles were further included into this review. Finally, N = 6 for meta-analysis. (Fig. 1).
