highly significantP value = .004
As Kadi et al showed in their review, the effects of satellite cell activation take approximately 50-90 days to propagate fully, which corresponds to our 2-month follow-up observation, when the increase of muscle fibers was found to be highly significant when compared to the control group ( P value = .004). 35 Nonetheless, all markers increased gradually in the active group and no significant changes were observed in the control group, and we can attribute the results seen in the active group to the HIFES + RF sessions.
