However, sympathetic activity after exercise, represented by the LF/HF ratio, showed a borderline significant increase compared to pre-exercise levels (MD = 1.06, 95% CI: −0.01 to 2.12, p = 0.052).

In the current study, we found that participants with chronic conditions showed an increasing trend in sympathetic activity, as indicated by the LF/HF ratio, while parasympathetic activity, measured by RMSSD, did not significantly decrease during or within one hour after exercise.
