    An artificial neural network method for predicting lower limb joint moments from kinematics parameters during counter-movement jump
    (2010-07-23) 黃長福; C. Huang; S. Shih
    The purpose of this study was to develop an artificial neural network (ANN) model for predicting the joint moments of lower limbs using solely the kinematic parameters during counter-movement jump (CMJ). Nine female volleyball players performed CMJ. The joint moments were calculated from experimental data by inverse dynamics (called “measured joint moments” in this study). A “303-3-303 ANN model” was developed with 303 neurons in input layer, three neurons in hidden layer and 303 neurons in output layers. The input variables were the left lower limb extension / flexion joint angles, and the output variables were left lower limb extension / flexion joint moments. The results revealed that the ANN model fitted the experimental data well indicating that the model developed in this study was feasible in the assessment of joint moments for CMJ.

    Biomechanical Analysis of Standing Long Jump: A 3D Study
    (2009-08-21) 黃長福; C. Huang; R.H. Tang
    Many studies had investigated 2D standing long jump, and some indicated that when jump with optimal load, the jumping performance would be improved. But till now, no study reported the 3D kinetic and kinematic data in standing long jump. The purpose of the study was to compare the kinetic and kinematic difference between restricted arm jump, normal jump, and loaded standing long jump.

    Effects of eight weeks pilates training on jump performance and limits of stability in elementary dancers
    (2010-07-23) 黃長福; Y. Wang; C. Huang; A. Lee
    Dance is not only a performing art, but also a highly rigorous athletic sport that is one of the most physically and mentally demanding athletic sports in the world (Shah, 2008). Dancers are a unique group of athletes in that they execute physically challenging movements while making them look beautiful and artistic. This performance ability requires a high level of fine motor control, strength, flexibility, and core stability. Pilates is a kind of conditioning which was used to exercise the body flexibility, muscles strengthen, and body alignment. It is suggested that the Pilates is good for joint flexiblity and core strengthing, however, limited study was conducted to evaluate its benefits on jump and postural stability. Therefore, the purpose of this study was to evaluate the effects of eight weeks Pilates exercise training on jump performance and limits of stability (LOS) in elementary dancers.
