1、背景人们认为,北岛的技术动作,特别是蹬腿动作非常完美。笔者作为致力于改善技术提高成绩研究的运动生物力学研究员,感到北岛游进技术几乎没有改进的余地。但是出发技术却有很大的改进空间。这在后来的分析中得到证实。但在当时,要对世界纪录保持者北岛的技术提意见,不仅需要勇气,还因北岛在出发技术有欠缺的情况下依然能取 1, the background People think, North Island’s technical action, especially leg movements very perfect. As a researcher in sports biomechanics working on improving technology to improve performance, I feel there is almost no room for improvement in the North Island touring technology. However, the starting technology has a lot of room for improvement. This was confirmed in later analysis. At the time, however, technical advice on world record holder Kitajima not only required courage, but also because of the North Island’s lack of starting skills
