Abstract： To reveal the different movement characteristics of Baduanjin before and after 14 weeks’trainingbetween beginners and professionals , the infrared capture test system , three-dimensional dynamometry , andsurface electromyography test system were used to collect Baduanjin movement data.AnyBody 7.0 Model-ing System was used to calculate the knee joint dynamics and muscle activation parameters of Baduanjinmovement. The results show that Baduanjin intervention can enhance the strength of knees and stability oflower limb joints , muscle fibers of different movements participate in different contractions ,and the muscleactivation degree is different. The muscle activation degree of tibialis anterior , rectus femoris , gastrocnemiusand biceps femoris is the highest in the second , third , fifth and seventh movements ,respectively. Beginnerscan adopt different actions to affect the stimulation of the muscles , and improve the scientificity of Baduan-jin exercise. The research results of this paper have verified the dynamic differences of knee joints of dif-ferent movements in Baduanjin , and calculated the characteristics of different muscle activation , which is of great significance in guiding beginners to practice Baduanjin.
