Changes in total creatine kinase (CK) activity for each recruit group before and up to five days after the military exercise (ME) (two tailed Wilcoxon signed rank test)

NBeforeAfterδp ValueSignificance
Values are median (range) total CK (U/l).
All of the recruits presented with raised CK values, which were reduced for the recruits sampled 12 hours, 48 hours, and five days after the ME. The recruits sampled after 24 hours and three days also showed some reduction in total CK but changes were not significant.
NS, not significant; S, significant.
