INTRODUCTION:
Analyse the biomechanical characteristics of patients with patellafemoral pain syndrome in Taiji practice.Through the biomechanical testing and inspection,to find out the connection about the pain with muscle strength?joint mobility and movement,prevetion the iujury about the taiji movement and adapt to the development about taiji.It will help athletes get great performance, promote the Taiji exercise routines and popularity for the public.
METHODS:
Selection of Beijing sports universitys school of martial arts 24 special athletes.Through the three-dimensional videography and force plate data to collect atheletes step action.And through the isokinetic test and joint angle ruler for taijiquan athletes to check for muscle strength and joint mobility.All of this for analysing lower limb mechanics characteristics about athletes.
RESULTS:
1.Biomechanical aspects: In the end of turn phase, the abduction angle of right hip between experimental group and control group have significant difference (P < 0.05). At the end of the feet support, the flexion angle of right knee and the extroversion angle of right knee between experimental group and control group have significant difference (P < 0.05).In turn phase, right ankle dorsiflexion have a significant difference (P < 0.05). The rest had no significant difference.At the step action,the knee stress of exernal rotation is greater at the angle of 30~35°and the knee stress of adduction is the second at the angle of 30~35°.2.Strength:the peak torque/weight in the experimental group has significant difference about knee extension(P < 0.05). And flexion/extension in the peak torque between experimental group and control group have significant difference (P < 0.05).At the experimental group,the best angle of power in the extension is 55~60°, the best angle of power in the flexion is 55~60°.The fagitue index is no different between experimental group and control group.
CONCLUSION:
1.The angle of knee extrovision about athletes with patellafemoral pain syndrome in the step action is a little big.2.Athletes should increase the angle flexion to decrease the stress.3.For taiji athletes with patellofemoral pain syndrome, the angle of hip adduction and ankle dorsiflexion is smaller.4.the quadriceps femoris both sides and the flexion/extension in the peak torque about athletes with patellafemoral pain syndrome is large gap.
