1 问题的提出 铅球是以远度计量成绩的田径项目。教练员、运动员和科研人员潜心研究、千方百计,采用各种训练方法、手段,归根结底,为的是将铅球推得更远。“连续变量”是我们设计的一种新训练方法,可能会对从事铅球专项训练的人们有所启迪和帮助。 只要稍为留心观察,就会发现我们周围大多数人可以轻松地将重量很轻的铅球推到十几米远,而却很难将7.26公斤的铅球推到十米,显而易见,投掷的铅球重量不同。但是,如果将投掷重量有意组合为一定差额的“连续变量”,在较轻重量至7.26公斤
1 put forward the question put shot is a track record of track and field project. Coaches, athletes and researchers devote themselves to research, do everything possible to adopt a variety of training methods, means, in the final analysis, in order to push the shot further. “Continuous variables” is a new training method we designed that may inspire and help people engaged in shot put special training. With a little bit of observation, you will find that most people around us can easily push a light weight shot to a dozen meters away, but it’s hard to push a 7.26-kg lead shot to 10 meters. Clearly, shot shot weights are different. However, if the throwing weight is deliberately combined into a “continuous variable” of a certain margin, at a lighter weight of 7.26 kg
