Data presented here to evaluate the effects of CrossFit intervention on students’ health-related physical fitness during physical education process through a meta-analysis. The procedure started with systematic screening following PRISMA guidelines using databases: Web of Science, SCOPUS, ScienceDirect, PubMed. Searching strategy and eligibility criteria of the literatures used in the meta-analysis are described. In all, 60 literatures were identified through predefined database and 6 of which fit for eligibility criteria. Meta-analysis was conducted by using RevMan-5.4.1. The random effects model was used to evaluate the effects of CF intervention on students. The outcomes from comparison between experiment and control groups were descripted with studies’ 95% confidence intervals (CI). The heterogeneity within comparison groups was estimated based on p-value of chi-squared (Q) test. I2 value also used for quantifying heterogeneity. Publication bias was estimated by using Rosenthal’s fail-safe number test (Nfs-T). Nfs-T = 19S - N (S = number of studies, p < .05, N = number of studies, p > .05). Tolerance level (TL) = 5K + 10 (K = all included studies). Sensitivity and subgroup analysis were conducted to remove study (studies) with deficiency that might influence effect in pooled group. The procedure illustrated here allows scholars to conveniently access and expand the pooled literatures and to utilize these data in future meta-analyses.
