Table 2. Comparison of SWV in different positions.

SWV	Relaxed position	Tensive position	Load (1 kg)	Load (2 kg)	All P values
Cmax (m/s)	2.61±0.36	3.67±0.50	4.28±0.68	4.85±0.76	<0.001
Cmin (m/s)	1.61±0.32	2.01±0.47	2.41±0.64	2.83±0.79	<0.001
Cmean (m/s)	2.08±0.33	2.78±0.40	3.32±0.63	3.81±0.76	<0.001

P<0.001 was found in comparisons between any two of the above four groups. SWV, shear wave velocity; Cmax, maximum velocities; Cmin, minimum velocities; Cmean, mean velocities.
