The validity and reliability of visual estimates of the kinematics of the vertical jump as would be common in qualitative analysis of human movement was studied. Sagittal plane videotapes of 12 females performing vertical jumps were rated on two occasions by three samples of subjects: 6 basketball coaches, 10 kinesiology students, and 5 kinesiology professors. Visual ratings were compared to values quantified by biomechanical analysis using the Peak Performance Technologies system. Assistant collegiate basketball coaches were unable to rate discrete body angles in the vertical jump accurately or consistently. Six of 10 college student raters could accurately and consistently rate over-all range of motion. Since only one of the kinesiology professors could accurately and consistently rate range of motion compared to the majority of the students, professional experience did not affect the ability to rate range of motion in the vertical jump in these subjects.
对垂直纵跳运动学进行视觉评估的有效性和可靠性进行了研究,这种评估在人类运动定性分析中很常见。12名女性进行垂直纵跳的矢状面录像在两个时间点由三组受试者进行评分:6名篮球教练、10名运动机能学学生和5名运动机能学教授。将视觉评分与使用Peak Performance Technologies系统通过生物力学分析量化的值进行比较。大学助理篮球教练无法准确且一致地对垂直纵跳中离散的身体角度进行评分。10名大学生评分者中有6人能够准确且一致地对整体运动范围进行评分。由于与大多数学生相比,只有1名运动机能学教授能够准确且一致地对运动范围进行评分,所以专业经验并未影响这些受试者对垂直纵跳运动范围进行评分的能力。
