Comparison of EPI Levels before and after Exercise in MICT, HIIT, and MICT+BFR Groups It was found that (1) there was no statistically significant difference in EPI levels among the groups before exercise ( p > 0.05); (2) compared with the pre-exercise EPI levels, the difference in blood EPI levels among the subjects in the MICT and MICT+BFR groups after exercise was significant ( p < 0.05), with increases of 8.3% and 18.1%, respectively; and (3) compared with the pre-exercise EPI levels, for the HIIT group, the difference in blood EPI levels in subjects after exercise was highly significant ( p < 0.01), with an increase of 30.4%, as shown in Table 1 .
