Initially the Shapiro-Wilk test was used to check the normality of data. To compare [lactate] in the different CrossFit WOD, two factor ANOVA tests were conducted: one with repeated measures, that is, an inter-subject factor, or group effect (3 levels G, M and W) and one with an intra-subject factor (2 levels pre- and postexercise). The effects of their interaction were also assessed.
To quantify muscular fatigue during the three CrossFit modalities, repeated measures ANOVA was performed for the factor time, contrasting it using the Mauchley sphericity test. When the hypothesis of sphericity was rejected, the univariate F statistic was used adjusting it with the correcting index Greenhouse-Geisser. When significant differences between measurements were detected, the post-hoc Bonferroni test was used.
All data were expressed as the M (mean) and SD (standard deviation). In all tests, effect size (ES) and the statistical power (SP) of the data were determined. Percentage gains were calculated using the formula ([post-pre]/pre X 100). Significance was set at P<0.05. All tests were performed using the SPSS package for Windows, version 18.0 (SPSS, Chicago, III).
