Kinematic analysis of aerobics using biomechanics: Comparisons between different complex movements in ten athletes
Abstract
Accurately executing high-difficulty aerobics movements is essential for improving competitive scores. This paper carried out a kinematic analysis of two complex movements, A104 and A136, ten aerobics athletes from three universities in Beijing. The results indicated minimal difference between the two movements during the plio push-up phase. However, in the airborne phase, A136 demonstrated a higher elevation and a larger angle of the elbow joints to facilitate subsequent landing. In the touchdown cushioning phase, A136 and A104 exhibited significant differences in the right hip joint angle and left shoulder joint angle. Amateur athletes had a higher degree of joint variation during airborne and touchdown buffer phases compared to professional athletes, making them more prone to joint injuries.
