Surface Electromyography Analysis of the Lower Extremities of Subjects Participating in Baduanjin Exercises

Table 2

Root mean square (RMS), average electromyographic activity (AEMG), integrated electromyogram (IEMG), mean power frequency (MPF), and median frequency (MF) before and after sixteen weeks, for the SG and CG. Data are means ± SD.

		Study group; ( = 55)		Control group; ( = 55)
		Pre	Post	Pre	Post
RMS (uV)	Vastus lateralis
	Vastus medialis
AEMG (uV)	Vastus lateralis
	Vastus medialis
IEMG (uVs)	Vastus lateralis
	Vastus medialis
MPF (Hz)	Vastus lateralis
	Vastus medialis
MF (Hz)	Vastus lateralis
	Vastus medialis

after sixteen weeks of Baduanjin exercise is significantly larger than the value before training ( < 0.025).
