HRV indices in the sitting position.
Graphs show changes in CVRR (A), HF (B) and L/H (C) in the sitting position between before and after intervention among the four sessions. CVRR: Coefficient of Variation of R-R Interval; HF: High Frequency Power; L/H: Low Frequency Power/High Frequency Power. ** P < 0.01 vs the sedentary session; ‡ P < 0.05 vs the music session. Data are expressed as means and SEM.
