Fig. 5From: Compression on trigger points in the leg muscle increases parasympathetic nervous activity based on heart rate variabilityChanges in mean gain of the transfer function during random frequency breathing after the application of pressure over the TPs points in the lower-limb muscle. Changes in the mean transfer magnitude between ILV and HR after the application of pressure onto TPs is shown (n = 6). A significant increase in the mean transfer magnitude was observed after pressure application over TPs. Asterisk indicates significant difference from the control (preM) (P < 0.05)Back to article page
