Figure 2a Left Pectoralis Major, Deltoid, Biceps Brachii,LatissimusDorsi NSC-330507 and Triceps Brachii muscle forces in LifeMOD Integrated EMG. The right and left integrated EMG of the five tested muscles for the four movement phases are presented in Figure 3a and and3b3b. Figure 3a The iEMG values of the left -side muscles in forward double arm support (T1), left arm support (T2), backward double arm (T3), and right arm support (T4) Figure 3b The iEMG values of the right side muscles in anterior double arm support (T1), left arm support (T2), posterior double arm (T3), and right arm support (T4) Discussion It is very important to improve stability of the double-leg circles on pommel horse because of its movement characteristics. Due to the complexity of the movement, research on DLC is relatively sparse in the literature.

Grassi et al. (2005) examined the pelvis and ankle behaviors during the movement and showed that the foot and ankle moved in a near circular fashion while the hip was maintained at about 180��. In a study of the movement on the novice and elite groups, Baudry et al. (2008) found greater differences of the foot-ankle 3D movements than the hip and shoulder joints between the groups. Baudry et al. (2009) further showed that the elite group had greater foot-ankle displacement in the horizontal plane than the notice group. Fujihara also studied the velocity changes of the center of mass in the horizontal plane (Fujhara, 2006; Fujihara et al., 2009). Our study is a pilot study that employed a single-subject design focusing on one elite athlete.

We not only employed the traditional 3D kinematics approach to investigate the displacement characteristics of COM and foot, but also established the computer model developed in Lifemod, to examine its validity, and verify the simulation results with the experimental sEMG data. The results showed that the COG displacements during the movement cycle of the DLC in the Lifemod model were in generally agreement with the displacement outputs of the and the 3D motion analysis (Table 1). These results showed relatively accurate model formulation and validity. The results from the foot displacement (Table 1, Figures 11 and and222)) of the model and 3D kinematics were also very close and consistent, and provided further evidence of the model��s accuracy.

However, the COG displacement curves showed some minor differences in the displacement in the anterior, posterior, mediolateral Anacetrapib and vertical directions between the two methods (Figure1 a and andb),b), demonstrating the complexity of the human body and central nerve system, and the model did not account for some of the details of the system. It is important to enhance the model and examine its validity, in comparison with experimental data. Previous studies have shown that the movement trajectory of COG, shoulder, hip and foot-ankle are important variables that influence the stability of the DLC movement (Baudry et al.
