一九七四年,我注意到很多女子背越式跳高运动员大多数都是在起跳脚的后部存在问题。我决定抓紧研究这一现象。首先,我用了早先的慢动作电影,但结果很不好,因为以前的慢动作影片频率太慢。一九七六年德国锦标赛时,我用了专门的16毫米高速摄影机,发现了在背越式跳高起跳时,脚落地部位的主要负担量。 In 1974, I noticed that most of the women’s back-jumpers were mostly at the back of the starting leg. I decided to pay close attention to this phenomenon. First, I used earlier slow motion movies, but the result was very poor because previous slow motion videos were too slow. At the German Championship in 1976, I used a dedicated 16mm high-speed camera and found the main burden on the foot of the foot during the FIBB jump.
